CAD vs. CAM: what is the primary focus of computer-aided manufacturing (CAM) compared with computer-aided design (CAD)?

Introduction / Context:
CAD (computer-aided design) concentrates on modeling and documenting the product. CAM (computer-aided manufacturing) turns those designs into manufacturing instructions, toolpaths, and production plans. Distinguishing these roles helps teams choose the right software stage for design versus execution.

Given Data / Assumptions:

• CAD produces geometry, tolerances, assemblies, and drawings.
• CAM generates machine instructions, process plans, and tooling definitions.
• Both often share models and data for continuity.

Concept / Approach:
CAM is focused on manufacturing execution: post-processing NC code, simulating tool motion, selecting cutting parameters, and orchestrating fixtures and operations. It integrates with shop-floor resources and may feed data to CNC machines, robots, and inspection equipment. While CAM can influence tool design, the core emphasis is translating product geometry into controlled, efficient production steps.

Step-by-Step Solution:
Contrast CAD’s design tasks with CAM’s production tasks.Identify the option that emphasizes production/tool control.Select that option as the correct characterization of CAM.

Verification / Alternative check:
Typical workflows: CAD model → CAM toolpath programming → G-code/robot paths → machining/production. This pipeline reflects the stated focus.

Why Other Options Are Wrong:
Management programs and communications are ancillary IT functions, not CAM’s core. PC-board design is a specialized CAD/EDA domain, not the definition of CAM. “None” is invalid because a correct description is provided.

Common Pitfalls:
Assuming CAM equals only “G-code generation”; it also includes simulation, verification, and tooling setup that impact quality and throughput.

Final Answer:
concerned with production and control of tool design
