我国的线切割是七十年代迅速发展起来的一种新工艺。它也象车、铣、刨、磨和热处理等一样有它自己独特的工艺规律。但由于它的历史较短、因素多、原因复杂等,虽然有许多从事电加工研究和工作的同志作了大量艰苦细致的工作,但许多东西至今还没有认识清楚,更没掌握它的规律,仍处于必然王国阶段。例如:线切割加工在控制、机械都正常,程序无误的情况下,切出的工件却不符合图纸要求,这就是大家通常所说的材料变形。变 China’s wire cutting is the rapid development of the seventies a new technology. It also has its own unique process laws like cars, mills, planing, grinding and heat treatment. However, due to its short history, many factors and complex causes, although many comrades engaged in electrical processing research and work have done a great deal of arduous and meticulous work, many things have not yet been clearly understood and even mastered its laws. Still in the inevitable stage of the kingdom. For example: wire cutting in the control, machinery are normal, correct procedures, the cut out of the workpiece does not meet the requirements of the drawings, which is commonly referred to as the material deformation. change
