ITPEC IP October 2024 Question 88
Which of the following is an appropriate explanation of CAD, as used in the manufacturing industry?
Explanation
Using computers in product design to raise design productivity and reliability — CAD stands for computer-aided design.
CAD lets engineers create and edit 2D drawings and 3D models on a computer, reuse existing parts, check dimensions and interference automatically and output consistent design documents. That speeds up design work and makes the design specifications more reliable.
Answer (d)
Why not others:
- •(a) — calculating the materials a production plan needs and ordering them is MRP (material requirements planning)
- •(b) — managing the components, semi-finished products and quantities needed to build a product is a bill of materials (BOM)
- •(c) — unified management of blueprints and component tables from design to manufacturing is PDM (product data management)
Key rule: CAD designs, CAM manufactures with computer control, MRP plans materials, and PDM manages product data across the stages.
