现在应用的数控线切割机床人工输入程序部分,大都仍采用8421码直接输入,即利用右面的五个输入板键给出编码,再按一下最左面的同步键发一同步脉冲读入。虽然在加工时,都尽量采用自动输入程序,但生产中还是要经常采用人工输入方式,例 The present application of CNC wire cutting machine manual input part of the program, most still use 8421 yards directly input, that is, using the right of the five input board key to give the code, and then click the leftmost sync button to send a sync pulse read. Although the processing, are trying to use automatic input procedures, but the production or to often use manual input method, for example
