Which of the following is an appropriate effect of CAD?
Explanation
Reusing design data to streamline the work — the effect of CAD (computer-aided design).
With CAD, drawings and 3D models are created and stored as data. Existing drawings and standard parts can be copied and modified instead of being redrawn, a change is made in one place, dimensions and interference are checked automatically, and the data can be passed on to CAM for manufacturing. Design work becomes faster and more reliable.
Answer (d)
Why not others:
- •(a) — calculating the required volume of material and ordering it is MRP (material requirements planning)
- •(b) — automating production processes so no human work is needed is factory automation (FA), with CAM and robots driving the machines; CAD supports design, not production
- •(c) — managing the whole series of production processes in an integrated way is CIM (computer-integrated manufacturing), which links design, manufacturing and management by computer
Key rule: CAD designs, CAM manufactures with computer control, MRP plans materials, and CIM integrates the whole production process.
