Design Guidelines For Machining - An Overview - Truventor Blog

Since plastics easily warp an increased minimum wall thickness is suggested during their machining. A rigid wall thickness would be 2.5 mm. The acceptable tolerance for CNC machining is 125 microns whereas the normal tolerance value can be 50 microns. The workable tolerances for machining purposes can be 20-50 microns.

Minimizing the cost of CNC parts (13 proven design tips) | Hubs

Other manufacturing costs: When you design parts with special requirements (for example, when you define tight tolerances or design thin walls), then special tooling, closer quality control, and more processing steps - at lower machining speeds - may be required. This, of course, has an impact on the total manufacturing time (and the price).

Machining Delrin: A Plastics Guide - AIP Precision Machining

Machining Delrin . Machining Delrin . It’s true that Delrin is an easy material to work with in terms of machining.
