把普通车床采用左右切削蜗杆的方法运用在数控车床上加工蜗杆,工序复杂而且加工效率不高,而采用循环指令编写数控加工程序,要每次对变化的参数、数据进行重新计算,工作量较大。介绍在GSK980TD数控系统采用宏指令程序来分层斜进法加工不同参数蜗杆。此方法的特点是当蜗杆模数、切削层数、刀头宽度、每刀切削用量等参数改变时只要修改其自身参数,而不需进行其他辅助计算,便可进行加工,以提高加工效率。
The use of ordinary lathe cutting worm about the use of CNC lathe machining worm, the process is complex and the processing efficiency is not high, and the use of cyclic instructions to write NC machining procedures, to change the parameters of each time, the data recalculated, the workload is more Big. Introduction GSK980TD CNC system uses a macro program to stratify oblique processing of different parameters of the worm. The characteristic of this method is that when the parameters such as the worm’s modulus, the number of cutting layers, the width of the cutter, the cutting amount of each knife are changed, as long as the parameters of the worm are changed, no other auxiliary calculation is needed, so as to improve the processing efficiency.
