铝合金高速加工中产生的残余应力和温度与刀具参数的关系

The need throughout the machining industry for cost reduction and increases
in productivity have contributed to new interest in high-speed machining. Even
though, many model for machining exist, most of them are for low-speed machining,
where momentum is negligible and material behavior is well approximated by
the quasi-static laws. In machining at high speeds momentum could be large and the
strain rate can be exceedingly high. For these reasons a
uid mechanics approach
to understanding high-speed, very high-speed and ultra-high-speed machining is attempted
