Typical for this strategy is that ae is 1 times Dc and ap is 1 to 1½ times Dc depending the workpiece material.
With HPM (High Performance Machining) you achieve an extremely high metal removal rate by using a much higher chip load than in general machining.
Tool characeristics:
Specially developed chip formers in the flute of the tool, tip protection with a small 45o face or corner radius, special smooth formed chip space and coating, with or without Weldon shank.
Machine requirements:
High stability, high power requirements, CNC control, rigid clamping system.
The application area is: Operations in a mass production environment where production time/lead time is of great importance or on single products where a high metal removal rate Q (cm3/min.) is required.
