Abstract:
The
research indicates it is impossible that cutting speed is improved
decuple in accordance with present cutting theory. A new theory on super
high-speed milling is put for-ward, in milling machining, the
temperature of cutting zone increases as a result of distortion and
friction, strength and hardness descend prominently. On the other hand,
the temperature of cutting tool is kept under 300℃ and the hardness is
invariable, so the ratio of cutting tool and workpiece hardness
increases and super high-speed (vc=8500m/min) milling is achieved. The
theory has already been proved reasonable.
Key words:
Super high-speed cutting Super high-speed milling
