CAD for tooling: which is a major benefit of using CAD specifically in tool and die design workflows?

Introduction / Context:
Computer-aided design (CAD) transforms tooling by enabling virtual checks before committing to fabrication. Collision detection and interference studies are key capabilities for jigs, fixtures, molds, and NC toolpaths.

Given Data / Assumptions:

• We are focused on tool design, not generic product styling.
• Interference checking reduces rework and scrap.
• CAM simulation often accompanies CAD models.

Concept / Approach:
With accurate assemblies and kinematic definitions, engineers simulate tool travel, clearances, and clamping. CAD/CAM systems flag collisions, gouges, and near-misses so designers can adjust tool geometry, fixtures, or operations. This saves time and cost compared to discovering issues during machining or try-out.

Step-by-Step Solution:
Model the tool, workpiece, and fixtures in CAD.Run motion/path simulations and collision checks.Revise design until no interference remains, then release to manufacturing.

Verification / Alternative check:
Common CAM workflows (toolpath verify, machine simulation) are built around preventing interference, underscoring this benefit.

Why Other Options Are Wrong:
(a) Cost fractions vary by industry; not a CAD benefit. (c) Materials handling coordination may improve, but it is not guaranteed. (d) CAD reduces trial-and-error but does not eliminate the need for validation.

Common Pitfalls:
Using incomplete models (missing fasteners/fixtures); ignoring machine kinematics that affect reach and collisions.

Final Answer:
Tool motions can be checked for interference between the tool and the workpiece before build
