线切割加工中如何克服变形、裂纹的问题已逐步引起人们的关注。我们对这个问题也是通过反复实践才逐步认识的。起初有些工件切割后尺寸总是出现明显偏差,检查机床精度、数控柜和程序都正常,最后发现是 Wire cutting how to overcome the deformation, the problem of cracks has gradually attracted people’s attention. We have gradually realized this issue through repeated practice. At first some of the workpiece size is always obvious deviation after cutting, check the machine accuracy, CNC cabinet and the program are normal, and finally found to be
