Thin Walls and Part Rigidity

Thin walls can flex during machining. This creates vibration, poor surface finish, dimensional variation, and higher scrap risk.

Why rigidity matters

Cutting forces push on the part. If the wall is too thin, the tool may cut a moving target. Shops may need lighter passes, special fixtures, or alternate sequences.

Material behavior

Plastics, aluminum, stainless steel, and titanium all respond differently. Stress relief and heat can also change final dimensions.

Design choices

Use thicker walls where possible, add ribs, increase corner radii, and avoid unnecessary deep pockets. These changes can reduce both machining cost and quality risk.
