ITPEC FE Morning October 2023 Question 72
ITPEC FE Morning October 2023 — Question 72 of 80
CAD (Computer-Aided Design) means using a computer to create product design drawings from attribute data such as shape and composition. It is the digital drafting/design phase before manufacturing.
Why not others:
- (a) Describes CAE (Computer-Aided Engineering) — simulating product behavior without physical prototypes
- (b) Describes CAM (Computer-Aided Manufacturing) — converting design drawings into machine processing instructions
- (d) Describes MRP (Material Requirements Planning) — calculating material volumes and timing from production schedules and BOM
Key rule: CAD = Design (draw it), CAM = Manufacturing (make it), CAE = Engineering simulation (test it virtually), MRP = Material planning (order it).
