Computer-Aided Design and Manufacturing: An Overview of Autocad and CAM, Cheat Sheet of Computer Aided Design (CAD)

University of NairobiComputer Aided Design (CAD)

An introduction to computer-aided design (cad) and computer-aided manufacturing (cam), focusing on autocad as a cad software example. Cad is used for creating and modifying designs, increasing productivity, improving quality, and facilitating communication. Cam is used for controlling machine tools in the manufacturing process, enhancing production speed and precision. Both cad and cam offer advantages and disadvantages, and are used by various professionals such as architects, engineers, and designers.

INTRODUCTION TO CAD SYSTEMS: AUTOCAD
What is CAD?
CAD is the acronym for Computer Aided Design or Computer Aided Drawing.
It is the use of computer systems to assist in the creation, modification, analysis, or optimization of a design.
CAD software is used to increase the productivity of the designer, improve the quality of design, improve
communications through documentation, and to create a database for manufacturing. CAD output is often in
the form of electronic design files for print or manufacturing operations.
Computer-Aided Design (CAD) is software is also used by architects, engineers, drafters, artists etc. to create
technical drawings and illustrations. CAD software can be used to create two-dimensional (2-D) drawings or
three-dimensional (3-D) models.
Examples of CAD Software
1. AutoCAD
2. CADopia
3. Harvard Graphics
4. AutoDesk
5. SolidWorks
6. MathCAD
7. QuickCAD
Who Uses Computer-Aided Design
Here is a short list of some people who would most likely use CAD in the job.
Architectures
Civil Engineers
Electrical Engineers
Facilities Manager
Interior Designers
Mechanical Engineers
Structural Engineers
Surveyors
Manufacturing Engineers
Acoustics Engineers
Fire Protection Engineer
Benefits/Advantages of the CAD Software
CAD software is being used on large scale basis by a number of engineering professionals and firms for various
applications. The most common application of CAD software is designing and drafting. Here are some of the
benefits of implementing CAD systems in the companies:
1) Increase in the productivity of the designer: CAD software helps designer in visualizing the final
product that is to be made, its sub-assemblies and the constituent parts. The product can also be given
animation and see how the actual product will work, thus helping the designer to immediately make
the modifications if required. CAD software helps designer in analyzing, and documenting the design.
All these factors help in drastically improving the productivity of the designer that translates into fast
designing, lower designing cost and shorter project completion times

Benefits/Advantages of the CAD Software

CAD software is being used on large scale basis by a number of engineering professionals and firms for various applications. The most common application of CAD software is designing and drafting. Here are some of the benefits of implementing CAD systems in the companies: 1) Increase in the productivity of the designer: CAD software helps designer in visualizing the final product that is to be made, its sub-assemblies and the constituent parts. The product can also be given animation and see how the actual product will work, thus helping the designer to immediately make the modifications if required. CAD software helps designer in analyzing, and documenting the design. All these factors help in drastically improving the productivity of the designer that translates into fast designing, lower designing cost and shorter project completion times

2) Improve the quality of the design: With the CAD software the designing professionals are offered large number of tools that help in carrying out thorough engineering analysis of the proposed design. The tools also help designers to consider large number of investigations. Since the CAD systems offer greater accuracy, the errors are reduced drastically in the designed product leading to better design. Eventually, better design helps carrying out manufacturing faster and reducing the wastages that could have occurred because of the faulty design. 3) Better communications: The next important part after designing is making the drawings. With CAD software better and standardized drawings can be made easily. The CAD software helps in better documentation of the design, fewer drawing errors, and greater legibility. 4) Creating documentation of the designing : Creating the documentation of designing is one of the most important parts of designing and this can be made very conveniently by the CAD software. The documentation of designing includes geometries and dimensions of the product, its sub-assemblies and its components, material specifications for the components, bill of materials for the components etc. 5) Creating the database for manufacturing: When the creating the data for the documentation of the designing most of the data for manufacturing is also created like products and component drawings, material required for the components, their dimensions, shape etc. 6) Saving of design data and drawings: All the data used for designing can easily be saved and used for the future reference, thus certain components don’t have to be designed again and again. Similarly, the drawings can also be saved and any number of copies can be printed whenever required. Some of the component drawings can be standardized and be used whenever required in any future drawings.

Advantages of CAD

  • Reduced storage space
  • Corrections can be made easily
  • Repetitive parts of the drawing can be saved and imported as part of a “CAD library”
  • CAD systems can be linked with CAM machines to produce objects straight from the drawings
  • 3D CAD designs can be made to look realistic by using the material library for clients to see
  • CAD designs can be easily shared between companies or department using email
  • CAD can be used to create simulated environments to show the client

Disadvantages of CAD

  • Work can be lost if the computer crashes
  • Work could be corrupted by viruses
  • Work could be stolen or “hacked”
  • Time taken to learn how to use the software
  • Initial costs of buying a computer system are high.
