Computer Aided Engineering

The computer-aided engineering (CAE) method mainly uses computers to analyse, design, and manufacture a product, project, and process. CAE relates to elements of CADD in industry. CAE often work as a recognised umbrella discipline that involves a lot of computer-aided technologies that are not limited to CAD, computer-aided industrial design (CAID), CNC, CAD/CAM, PDM and CIM, plus the Internet and other technologies that collaborate on various projects. Talking about CAE it often focuses on mechanical design and product development automation.

Its most familiar elements of CAE where simulation and solid modelling, analysis, optimisation and testing of mechanical structures. It adds a system that uses digital prototypes. FEA is a kind of process that is often associated with Computer-Aided engineering.

Design application

CAE sits alongside related disciplines — finite element analysis (FEA), computational fluid dynamics (CFD), multi-body dynamics, and design-validation simulation — within the broader product development workflow. While CAE focuses on simulating and analysing product behaviour, the supporting engineering design process feeds CAE with the geometric models it analyses. Below is a simplified example walking through a lifting hook design from concept to CAE-validated output.

The lifting hook is one best example, and the following information is an introduction to CADD in the engineering design process.

STEP – 1

Step 1 helps to identify the problem along with adding design constraints. It comes with a constraint and a condition adding a specific shape, size, or requirement. It defines a design that satisfies to achieve a successful design. The problem statement describes the requirements and constraints for a forged-steel lift hook that support a 3000-pound load.

STEP – 2

Step 2 offers a sketch of the initial design based on the solution to the problem. The sketch comes with hand-drawn that use CADD as a sketching tool. CADD systems require the creation of a digital sketch as an element of the CADD process. The hand-drawn sketches come with a common practice that especially comes during early design.

STEP – 3

Step 3 generates an initial three-dimensional solid model from the hand-drawn sketch — the geometry that CAE will analyse. Using finite element analysis (FEA) software, engineers then study how the model behaves under load. FEA applies the finite element method (FEM) to solve mathematical equations related to engineering design problems, including structural and thermal issues.

STEP – 4

Step 4 offers structural stress analysis applied to that lifting hook to simulate a real-world lift.

STEP – 5

Step 5 optimise the design to reduce material with improving shape while maintaining a sufficient working strength. Users can perform design optimisation, adding manual calculations and tests and repeated FEA simulations. It offers an optimised lift hook with CAD solid model.

STEP – 6

Step 6 can re-analyse the model that confirms a solution to the design problem.

STEP – 7

The last step 7 is to use the CAD solid model to prepare two-dimensional (2-D) detail drawings and a digital model format supported by computer-aided manufacturing (CAM) software. The manufacturer mainly uses the supplied data to create the forging equipment necessary to produce the lifting hook.

Professional approched

A wide variety of jobs are currently available for qualified CADD professionals. Note that the kinds of tasks they may allow is always traditional. In addition to this, they create drawings that are responsible for working in some of the following areas, including:

To prepare freehand sketches on the shop floor and convert the sketch with finished CADD drawing.

What is difference between CAD and CAE?

CAD (Computer-Aided Design) and CAE (Computer-Aided Engineering) are both integral parts of the product development process, but they serve different purposes.

CAD (Computer-Aided Design):
– CAD software is primarily used for creating 2D or 3D digital models of products or parts.
– CAD tools are focused on facilitating the design and drafting process, allowing engineers and designers to visualize and develop concepts.
– CAD software enables precise geometric modeling, drafting, and annotation of designs.
– It’s commonly used in industries like architecture, automotive, aerospace, and consumer goods for creating product designs, architectural plans, and engineering drawings.

CAE (Computer-Aided Engineering):
– CAE software is used to simulate and analyze how products will perform under different conditions.
– CAE tools allow engineers to perform virtual testing, optimization, and validation of designs before physical prototypes are built.
– CAE encompasses various types of analyses including structural analysis, thermal analysis, fluid dynamics (CFD), and electromagnetic simulation.
– It helps in understanding product behavior, identifying potential issues, and optimizing designs to meet performance criteria and regulatory standards.
– CAE is commonly used in industries such as automotive, aerospace, energy, and manufacturing for design validation and optimization.

What does a CAE engineer do?

A CAE (Computer-Aided Engineering) engineer utilizes computer software and simulations to analyze, simulate, and optimize engineering designs and processes. Their responsibilities often include:

Simulation and Analysis: They use specialized software to simulate how products or systems will perform under different conditions. This could involve stress analysis, fluid dynamics, thermal analysis, or electromagnetics depending on the field.
Design Optimization: They work to optimize designs to meet specified criteria such as performance, efficiency, safety, or cost-effectiveness. This involves running simulations with different parameters to find the best design solution.
Product Development Support: CAE engineers often collaborate closely with design engineers to provide insights and feedback during the product development process. They may suggest design modifications based on simulation results to improve performance or reduce potential issues.

Prototyping

A prototype is a functional part model of design; it is used as the basis for continuing the production of the ﬁnal part or assembly. The terms prototype and model are often used interchangeably. Prototypes are used to determine if a new design works as intended. A prototype is commonly used as part of the product design process to enable engineers and designers to explore design alternatives, determine unknown characteristics in the design, ﬁnalize part tolerances, conﬁrm customer interest in the design, verify design performance, coordinate with marketing and sales, and test theories before starting full production of a new product. A variety of processes can be used to create a prototype. The processes range from creating a digital model to developing a solid physical model of a part directly from a 3-D CAD model data and to fabricating a model using standard manufacturing processes. A company generally contracts with another company that specialises in developing prototypes quickly and accurately. Some companies have their own prototype development departments. A prototype is generally different from the ﬁnal production part because special processes and materials are used to quickly create a part that can be used to simulate the actual part.

The development phase of the design process is when a fully functioning prototype model is made that operates at the desired quality level. A physical prototype can be machined, moulded, or created using rapid prototyping processes. Parts are assembled into the desired product and then tested to determine if the design meets speciﬁ c product requirements such as weight and performance. The design might have to return to the concept phase for reevaluation if some aspects of the design do not perform as intended or manufacturing process appears to be too costly. After the functioning prototype has been built and tested, drawings are created for continuing to full production of the product.

Digital prototyping

A digital prototype is a computer-generated model or original design that has not been released for production. The most common and useful digital prototype is a 3-D solid model. A solid model digital prototype functions much like a physical prototype, is often just as or even more accurate, and can be subjected to real-world analysis and simulation. Digital prototyping is the method of using CAD to help solve engineering design problems and provide digital models for project requirements. Successful digital prototyping offers several ben-eﬁ ts to the engineering design process. It provides companies with a deeper understanding of product function, enables the simulation of product performance as part of a complete system, offers interactive and automatic design optimisation based on requirements, and assists other areas of product development and coordination.

Digital prototyping can support all members of a product development team and help communication. Designers, engineers, and manufacturers use digital prototyping to explore ideas and optimise and validate designs quickly. Salespeople and marketers use digital prototyping to demonstrate and describe products. Depending on product requirements and company practices, digital prototyping can reduce or eliminate the need for physical prototypes, which are often expensive and time-consuming to create and test. The figure shows an example of digital prototyping to model, analyse, simulate, and visualise products in a virtual environment.

Rapid prototyping

Rapid prototyping is a manufacturing process by which a solid physical model of a part is made directly from 3-D CAD model data without any special tooling. An RP model is a physical 3-D model that can be created far more quickly than by using standard manufacturing processes. Examples of RP are stereolithography (SLA) and fused deposition modelling (FDM), or 3-D printing.

Three-dimensional CAD software such as AutoCAD, Autodesk Inventor, NX, Pro/Engineer, and SolidWorks allows you to export an RP ﬁ le from a solid model in the form of a .stl ﬁle. A computer using postprocessing software slices the 3-D CAD data into .005-.013 in. thick cross-sectional planes. Each slice or layer is composed of closely spaced lines resembling a honeycomb. The slice is shaped like the cross-section of the part. The cross-sections are sent from the computer to the rapid prototyping machine, which builds the part one layer at a time. The SLA and FDM processes are similar, using a machine with a vat that contains a photosensitive liquid epoxy plastic and a ﬂat platform or starting base resting just below the surface of the liquid as shown in Figure. A laser-controlled with bi-directional motors is positioned above the vat and perpendicular to the surface of the polymer. The ﬁrst layer is bonded to the platform by the heat of a thin laser beam that traces the lines of the layer onto the surface of the liquid polymer. When the ﬁrst layer is completed, the platform has lowered the thickness of one layer. Additional layers are bonded on top of the ﬁrst in the same manner, according to the shape of their respective cross-sections. This process is repeated until the prototype part is complete.

Another type of rapid prototyping called solid object 3-D printing uses an approach similar to inkjet printing. During the build process, a print head with a model and support print tip create the model by dispensing a thermoplastic material in layers. The printer can be networked to any CAD workstation and operates with the push of a few buttons as shown in Figure.

Rapid prototyping has revolutionized product design and manufacture. The development of physical models can be accomplished in significantly less time when compared to traditional machining processes. Changes to a part can be made on the 3-D CAD model and then sent to the RP equipment for quick reproduction. Engineers can use these models for design verification, sales presentations, investment casting, tooling, and other manufacturing functions. In addition, medical imaging, CAD, and RP have made it possible to quickly develop medical models such as replacement teeth and for medical research.

Rapid injection moulding prototyping

Rapid injection moulding is an automated process of designing and manufacturing moulds based on customer-supplied 3-D CAD part models. Because of this automation, lead time for the initial parts is cut to one-third of conventional methods. Cost-saving varies with the number of parts being produced, but rapid injection moulding can also have a substantial cost advantage in runs of up to thousands of parts. Rapid injection moulding produces quality moulds using advanced aluminium alloys and precise, high-speed CNC machining. Parts can be moulded in almost any engineering-grade resin. The figure shows the 3-D CAD part model, the injection moulded part in the mould, and the resulting rapid injection moulded part.

Subtractive rapid prototyping

CNC machining of parts has been around for decades, but the use has typically not been applied to short lead-time prototype development. Subtractive rapid prototyping uses proprietary software running on large-scale computers to translate a 3-D CAD design into instructions for high-speed CNC milling equipment. The result is the manufacturing of small quantities of functional parts very fast, typically within one to three business days. A variety of materials, including plastics and metal, can be used with sub-tractive rapid prototyping. The figure shows the 3-D CAD part model, the CNC machining process, and the machined part.

Conventional machining prototyping

Some companies have a machine shop combined with the research-and-development (R&D) department. The purpose of the machine shop is to create prototypes for engineering designs. Drafters generally work with engineers and highly skilled machinists to create design drawings that are provided to the machine shop for the prototype machining. This practice generally takes longer than the previously described practices, but the resulting parts can be used to assemble a working prototype of the product for testing.

What are the prototyping techniques in engineering?

Prototyping is a crucial phase in engineering where initial designs or concepts are transformed into physical models or working versions of a product. There are several prototyping techniques used in engineering, each with its own advantages and applications. Here are some common ones:
3D Printing/Additive Manufacturing: This technique builds objects layer by layer from digital models. It’s highly versatile and allows for complex geometries.
CNC Machining: Computer Numerical Control (CNC) machines use pre-programmed sequences to cut, drill, and shape materials with high precision. It’s suitable for producing functional prototypes from various materials like metal, plastic, or wood.
Injection Molding: Ideal for producing large quantities of prototypes, injection molding involves injecting molten material into a mold cavity. It’s commonly used for plastics.
Vacuum Casting: This technique involves making a silicone mold from a master model and then pouring a resin into the mold. It’s great for producing small batches of prototypes with properties similar to injection-molded parts.
Sheet Metal Prototyping: Sheet metal can be cut, bent, and formed to create prototypes of metal parts or enclosures.
Laser Cutting: Laser cutting uses a high-powered laser to cut through materials like acrylic, wood, or metal sheets. It’s useful for creating flat prototypes or intricate designs.
Foam Modeling: Foam blocks are carved or milled to create rough prototypes of products or parts.
Electronics Prototyping: Breadboarding and soldering components onto perfboards or custom PCBs are common techniques for prototyping electronic circuits.
Rapid Prototyping Techniques: These encompass various fast and low-cost methods like foam core modeling, cardboard modeling, or even LEGO prototyping for quick visualization and concept testing.
Soft Prototyping: Involves using flexible materials like fabrics or elastomers to create prototypes, commonly used in wearable technology or soft robotics.

What is prototype model in engineering?

In engineering, a prototype model is a preliminary version or representation of a product, system, or component that is created to test and validate design concepts, functionality, and performance before full-scale production. Prototyping is an essential step in the product development process as it allows engineers and designers to identify and address potential issues early on, saving time and resources in the long run.
A prototype model can take various forms depending on the nature of the project and the specific requirements. It could be a physical model made from materials such as plastic, metal, or composites, or it could be a virtual model created using computer-aided design (CAD) software or simulation tools.

The primary purposes of creating prototype models in engineering include:
Concept Validation: Prototypes help validate design concepts and ideas to ensure they meet the intended requirements and objectives.
Functionality Testing: Engineers use prototypes to test the functionality and performance of a product or system under real-world conditions. This helps identify any flaws or limitations that need to be addressed.
Iterative Design: Prototyping allows for an iterative design process where changes and improvements can be made based on feedback from testing and evaluation.
User Feedback: Prototypes can be used to gather feedback from potential users or stakeholders, providing valuable insights for refining the design and enhancing user experience.
Cost Reduction: By identifying and addressing issues early in the development process, prototypes help minimize the risk of costly errors and redesigns during later stages of production.

Engineering drawing is a common language that describes the process of creating drawings for engineering and architectural application. The engineering drawings work the best and accept standards and format.

It offers an efficient way to communicate and use specific data with adding design intent. The Engineering drawings do not require work and interpret of others’ drawings. It comes with decorative drawings along with using artistic paintings. Using a successful engineering drawing, the user can describe a specific item that the drawing viewer understands without misinterpretation.

One can talk about the term engineering drawing, known for its Drafting, mechanical drawing, mechanical Drafting, engineering drafting, technical Drafting and technical drawing. The Drafting comes with a different graphic language that uses lines, symbols, and other notes to describe objects for an industry like manufacturing or construction. There are technical disciplines that use Drafting, covering civil, architecture, electrical engineering, electronics, piping, manufacturing, and structural engineering.

The term mechanical drafting comes with alternate meanings. The manufacturing industry comes with mechanical Drafting, where the name is derived from mechanisms. The construction industry uses mechanical Drafting in terms of drafting heating, ventilating, and air-conditioning (HVAC) systems. It comes with a mechanical portion of an architectural project.

Whereas if we talk about manual Drafting, it’s a term that describes traditional drafting practice, including pencil or ink onto a medium. It covers paper or polyester ﬁlm, which supports drafting instruments and equipment. Computer-aided Drafting (CAD) has taken the place of manual Drafting, where the CAD uses computers for drafting. CAD also refers to computer-aided design when computers are used to design.

Engineering drawing

Engineering drawings add various concepts that cover instructions, engineering requirements, and proposals. It comes with multiple people and includes different individuals involved with a project. An engineering drawing comes with a complete set of engineering designs that offer data needed to manufacture an item or product. It includes machine parts, consumer products and many more structures.

The drawing study covers medical instruments that completely describe all geometric features’ location and size. Later, it identifies the characteristics of the part. It mainly uses the material along with manufacturing precision. Also, the medical instrument company uses the drawing to share the document design, which intends to be a part of manufacturing. Let’s say how difficult it can be to understand the engineering drawing.

Actually, the engineering drawing comes with an architectural drawing that is mainly used for home re-modelling projects. The drawing uses one sheet in a set of communication with architectural style, size, and location with building features and taking care of the construction methods and materials.

The drawing offers sheets that communicate architectural style, the size and location of building features, and construction methods. The drawings are set to obtain to pay for construction, make permits and legally begin construction. It offers accurate cost estimates that bring impossible and impractical construction without engineering drawings.

Computers In Design and Drafting

The computers offer revolutionised business along with adding industry process. It covers design and drafting practices with ease. Computer-aided design and drafting (CADD) is a process that uses a computer with CADD software for design and drafting applications. Also, the software is a program that enables a computer to perform speciﬁc functions and accomplish a task. Talking CAD is the acronym for computer-aided design, referred to as computer-aided Drafting.

Computer-aided design and computer-aided Drafting offer specific aspects of the CADD process. It mainly uses CADD for the design and drafting process to get accurate and faster CAD design. Several industries mostly use engineering and architecture to get a better outcome. Most engineering industries and educational institutions use manual drafting practices that evolved to CADD.

Whereas CADD allows drafters and designers to produce accurate drawings with neat and matched industry standards. CADD makes architectural drawings with artistic ﬂair lettering and line styles, including a matched appearance with the ﬁnest handwork available. In addition to this, CADD drawings come consistently from one person or company to the next. It supports enhancing the ability of designers and drafters, adding creativity to it. It uses new tools such as solid modelling, animation, and virtual reality.

What is basic engineering drawing?

Basic engineering drawing refers to the fundamental principles and techniques used to create clear, accurate, and standardized drawings that convey technical information effectively. These drawings serve as a visual representation of objects, components, or structures, and they are essential for communication, documentation, and manufacturing processes in engineering disciplines such as mechanical, civil, electrical, and architectural engineering.
Here are some key aspects of basic engineering drawing:
Orthographic Projection: This is the primary method used to represent objects in engineering drawings. It involves creating multiple 2D views of an object from different perspectives (front, top, side, etc.) to fully describe its shape and features.
Dimensioning: Dimensions are added to engineering drawings to specify the size and location of features accurately. This includes linear dimensions (length, width, height), angular dimensions (angles), and geometric dimensions (tolerances, concentricity, symmetry, etc.).
Drawing Standards: Basic engineering drawings adhere to standardized conventions and symbols to ensure consistency and clarity. Common standards include ASME Y14.5 for dimensioning and tolerancing, ISO 128 for technical drawings, and specific industry standards as needed.
Line Types and Weights: Different types of lines (e.g., continuous, dashed, hidden) and line weights are used to differentiate between different elements of the drawing, such as object lines, dimension lines, and centerlines.
Title Block: Each engineering drawing typically includes a title block containing essential information such as the drawing title, scale, revision history, author, and date.
Symbols and Notations: Symbols and abbreviations are used to represent specific features, materials, processes, and annotations on engineering drawings. These symbols help convey information concisely and universally.
Scale: Drawings may be drawn to scale to represent objects accurately relative to their actual size. Common scales include full scale (1:1), half scale (1:2), and so on.

What are engineering drawings used for?

Engineering drawings serve as the universal language of engineers, architects, and designers. They are used for several purposes:
Communication: Engineering drawings communicate the design intent and specifications to various stakeholders involved in the manufacturing or construction process. This includes engineers, fabricators, machinists, contractors, and inspectors.
Visualization: They provide a visual representation of the final product, enabling stakeholders to understand how the object or structure will look and function.
Documentation: Engineering drawings document the design, dimensions, materials, tolerances, and other critical information necessary for manufacturing or construction. They serve as a reference throughout the lifecycle of the product or project.
Quality Control: Manufacturers use engineering drawings to ensure that the final product meets the required standards and specifications. They serve as a basis for quality control checks and inspections.
Legal and Regulatory Compliance: In regulated industries such as aerospace, automotive, and construction, engineering drawings are essential for complying with legal and regulatory requirements. They demonstrate that the product or structure meets safety, environmental, and other regulatory standards.
Modification and Maintenance: Engineering drawings are used for maintenance, repair, and modification purposes. They provide guidance on how to disassemble, repair, or modify a product or structure without compromising its integrity.

Engineering design and drawing offer a broad subject that includes many theories and practices. It has different forms of drawing at the lunch table as a basic sketch of a new product idea drawn on a napkin.

Additionally, the drawing comes in the form of a complex series of models for a new automotive design. It uses hundreds of formal drawings that require the construction of a skyscraper. One could learn the purpose and requirements and create meaningful engineering drawings by using this textbook to study engineering drawing and design. The engineering design applications offer an early explanation along with systematic problem-solving techniques.

What is the engineering design application

We use speciﬁc engineering projects or general design along with drafting concepts. The engineering design application mainly uses post guides through a basic example of an engineering design process. It begins with an idea and a basic sketch that ends with manufacturing an actual product.

From an Idea to a Product

The engineering projects and design ideas establish or occur along with an informal setting. For instance, a hand-tool manufacturing company engineer uses a typically adjustable wrench to complete a common home-repair task.

They used the wrench, where the engineers discovered that it was difﬁcult to access a conﬁned location and remove a nut on a piece of equipment. The engineer additionally imagined how the company could manufacture, design, and market a new wrench. We use features that help in making the tool usable in cramped locations. The other day, the engineer and a colleague used the drafting department. The engineer mainly sketches the idea for the new wrench on a napkin by communicating the design to the drafter.

THE ENGINEERING DESIGN APPLICATION fig1.1

The sketch mostly shows the idea of taking the existing tool design that creates a whole new handle adding an ogee or S-shaped curve design. Additionally, the sketch communicates the concept that takes a current tool with creating a fresh hold of an S-shaped curve design.

THE ENGINEERING DESIGN APPLICATION fig1.2a

Later the same day, the drafter would offer the three-dimensional (3-D) solid model ﬁles using existing wrench design based on the computer-aided design and drafting (CADD) system.

THE ENGINEERING DESIGN APPLICATION fig1.2b

The user mainly uses drafter copies that revise the existing design based on the engineer’s sketch. The drafter represents the engineer’s new model, who is pleased with the results and requests of a rapid prototype. Rapid prototyping (RP) is a process that creates a physical and functional model from a computer-generated 3-D model. It uses an RP machine, known as a 3-D printer. The RP machines are available that build prototypes from various materials like paper and liquid polymer. The hand-tool company do not have an RP machine. Therefore, the drafter sends ﬁles of the design to a company specialising in RP. The engineer and drafter receive a prototype two days later.

The figure shows the prototype of the new wrench design. The design team tests the prototype in an application similar to what the engineer experienced at home. The prototype worked as expected.

By the next afternoon, the drafter completes the set of working drawings shown in Figure and sends the drawings to the manufacturing department to manufacture and assemble the new product. The manufacturing department needs lead time to design and make the forging dies required to reproduce the parts. Lead time is the time interval between the initiation and the completion of a production process. Forging is the process of shaping malleable metals by hammering or pressing between dies that duplicate the desired shape. The hand-tool company is small, so the drafter is also responsible for creating catalogue art and copy for marketing the product.

Assembly Drawings and Parts List & Detail drawing of the new wrench body part

Detail drawing of the new wrench JAW part.

Detail drawing of the new wrench GEAR part.

Detail drawing of the new wrench PIN part.

Less than two months after the engineer had the initial idea, the first production run of new wrenches is ready to sell. The figure shows the finished product.

What is the engineering design application

We have the best design team that tests the prototype in an application. It works similar to what the engineer experienced at home. The prototype worked as expected. The drafter supports along with completing the set of working drawings by the next day and sends the drawings to the manufacturing department. It helps to manufacture and assemble the new product. The manufacturing department needs lead time to design and make the forging dies required to reproduce the parts. The Lead time is the time interval between the initiation and the completion of a production process. It helps in the process of shaping malleable metals that presses between dies and duplicate the desired shape. Additionally, the hand-tool company is relatively small. It helps to draft for creating catalogue art and add copy for the product marketing.
