平面槽铣削加工中环切方法

A New Method for Helical Cutting of Planar Pocket

内槽的数控铣削加工常采用环切或行切方式,计算环切走刀时铣刀中心轨迹的方法有循环法和区域法。本文在这两种方法的基础上介绍了一种改进的方法,即按区域法的原理求出最内点,再按循环法计算刀具中心轨迹。同时还介绍了凹多边形槽的处理方法。

There are two methods to calculate the tool path for helical cutting of pocket.Based on this two method,we design a new method which is easy to be completed on micio-computer.
