1.10 Mechanical Engineering Applications of CAD
Following is a brief description of the applications of CAD in mechanical engineering.
Two Dimensional Drafting: This is the most common use of a CAD package. 2-D drawings are used for manufacturing a product.
Report Generating: To generate reports and bill of materials. Spreadsheets and word-processors can be linked to provide a report writing facility.
3-D Modeling: To create the wireframe, surface and solid models. The 3-D models are for concept verification, manufacturing, FEA, etc.
Finite Element Analysis: FEA package is used for pre-processing, analysis, and post-analysis of structures. For this application, a CAD package contains both the modeling and analysis modules.
Manufacturing: manufacturing software is usually called CAM, and contains CAD software as one of the components. CAM software provides capabilities of carrying out 2 and 3-axes machining.
