Requesting Post Processors

A post processor is needed to translate toolpath information from Mastercam into a NC format the machine tool can interpret. Each Mastercam post processor is unique due to factors including specific machine and control makes and models, as well as customer preferences. To get the best results, you will need to download the post request form. You can find the forms at the links below.

Note: Due to differences in machine controls, parameters, and model, please attach some sample code that will better determine the best post for your machine.

All post request and sample code can be sent to mastercamsupport@mlc-cad.com.
