数控电火花线切割穿丝孔加工位置及精度影响

The Threading Hole Processing Position and Accuracy of Numerical Control Electrospark Wire-electrode Cutting

随着模具产业和其它加工制造业的飞速发展,对电火花线切割各项工艺指标如尺寸精度、表面粗糙度等都提出了越来越高的要求。在电火花线切割加工中打穿丝孔是一个经常遇到的基本问题,穿丝孔是钼丝相对于工件运动的起点,同时也是程序执行的起始位置。穿丝孔的位置对于加工精度及切割速度关系甚大,文中就打好穿丝孔位置及精度问题进行了论述。

With the mold industry and other manufacturing industry＇s rapid development, the electrospark wire-electrode cutting of various process parameters such as size precision, surface roughness and so put forward more and more requirements. In the electrospark wire-electrode cutting processing through the wire hole is a frequently encountered problems, threading hole is the starting point of molybdenum wire moving relative to a workpiece, but also the procedures for the implementation of the starting position. The threading hole location on machining accuracy and cutting speed are in a great relationship, this paper lay the threading hole position and accuracy are discussed.
