Recent - Latest Trends in Machining and Machine Tools




April 2016
Entry from a textbook

High Speed machining or cutting is defined as the cutting speed above which shear localization develops completely in the primary shear zone.

600 to 1,800 metres/minute is termed HSM.
1,800 to 18,000 metres/minute is termed Very high speed machining
Above 18,000 metres/minute it is termed ultra HSM

In the case of difficult to machine materials, High throughput machining is used.

Grinding
Generally, the wheel velocity between 30 and 35 m/s is defined as conventional grinding;
The wheel speed exceeding 45 to 50 m/s is defined as high speed grinding;
The wheel speed between 150 and 180 m/s or higher is defined as Super-high Speed Grinding.

Volkswagen Group China applied the high speed grinding technique to grind engine camshafts. The wheel rotation-velocity is 4300 r/min, and 3000 workpieces can be ground each wheel dressing.
