Roughing of a screw | GO2cam Help Center

Roughing of an endless screw on a lathe with the management of stock.

Key Points

This cycle works as the grooving cycles, with stock management.

The pitch of the screw is constant.

Settings: only one section of the groove has to be drawn and the cycle will duplicate it along the profile according to the pitch defined and the ending Z of the screw.

Those parameters are defined in the strategy page.

▶️ You can watch a video to set up and define the machining of the screw:
