强冷散热对磨削表面残余应力的影响

Affection on Residual Stress in the Grinding Surface Obtained in Preemption Grinding

工件表面残余应力的性质和大小直接影响着工件的使用性能。对于大多数工件因热应力塑性变形而产生的残余拉应力采用强冷散热的方法 。

The usage properties of parts are affected directly by the properties of residual stresses. The extensive residual stresses of most parts are caused by plastic reformation from heat stress. We can partly control the property of residual stresses with compulsive cold.
