abs accuracy value for plastic parts/mold design/machining

[al204]

Hello ProE users...

I have a question concerning the abs accuracy parameter that I should use to model plastic parts and the molds that will be designed after them.

What value are you currently using?

At the moment I´m using 0,0254 mm (0,001 inches). Is this tolerance too high??

So far I have had good results with this value, I just want to know what most of you out there are using and why.

thanks, best regards

Alvaro,

A guru once taught me to always try to model at an absolute accuracy of 0.0001" because most nc machines work to 4 decimal places. Ithas always worked good for me. Also when you are using Mold/Cast to build plastic molds, that accuracy will insure that you don't have trouble.
