论积屑瘤对加工精度的影响

在精切削加工时,为什么采用极低或高速切削时工件表面粗糙度低？为什么采用润滑性能好的切削液、刀具前角大、进给量和刀具主偏角小工件表面粗糙度低？为什么工件材料硬度高、脆性大的材料,在切削时粗糙度低？等等。怎么保证加工质量,值得深思。本文论述了在切削塑性材料过程中一种常见的物理、力学作用下,积屑瘤的生长条件,消失、防止措施,及对精加工表面粗糙度产生的影响。

Concerning Bue to Machining Accuracy

In fine machining, with extremely low or high speed cutting surface rouglmess of workpiece when low？ Why good performance by lubrication coolant, cutting Angle, feeding and main landform small tool surface roughness of workplece low？ Why the workpiece materials, high hardness and brittleness of materials, cutting when lower roughness？ And so on. How to guarantee the quality and machining. This paper discusses the process of plastic material cutting a common physical and mechanical function, bue tumor growth condition, disappear, preventing measures, and the precision of the surface roughness.
