How does the G75 code work?

The G75 code is a canned cycle for external or internal diameter radial grooving operations [1]. This cycle allows the tool to advance along the X-axis, enabling stable chip evacuation and safe, multi-pass grooving operations [1].

The basic operation of the G75 cycle is as follows:

1. The tool advances in the X-axis (external or internal diameter) from a specified starting point [1].
2. At each feed step, it retracts slightly or applies a specified dwell to break the chip and evacuate it safely [1].
3. This cycle is repeated until the specified final depth is reached [1].

This cycle helps reduce scrap rates and extend tool life by ensuring chip control in deep grooving operations [1]. When programming the G75 cycle, incremental tool movement within the workpiece, retraction for chip management, and repeated plunging motions until the final depth is reached are observed [1].
