Process

The SysMillThread cycle can be used to mill inner and outer threads. The path for thread milling is based on a helical interpolation. The centre point of the thread is the starting point. This is where the tool must be positioned when the cycle is called. At the end of the cycle, the cycle retracts to the starting point.

There are three tool types available:

• Tool type 1: The thread is milled once to final depth by the full profile thread milling cutter.
• Tool type 2: The indexable insert thread milling cutter is offset by the cutting width of the indexable inserts until full depth is reached.
• Tool type 3: The single-flute thread milling cutter traverses the thread pitch from top to final depth in a continuous helical movement.
