Critical dimensions are the measurements that directly affect fit, function, or assembly. Identifying them clearly helps manufacturers prioritize accuracy where it matters most and reduces the risk of costly rework.

Plastics machine very differently from metals—heat, tool geometry, and cutting strategy can quickly cause melting, chatter, or poor finish. Avoiding common mistakes improves part quality and reduces scrap.

Aluminum alloys vary in strength, machinability, corrosion resistance, and finish quality. Selecting the right grade helps meet performance requirements while keeping machining efficient and budget.
