固定循环是加工中心编程的一部分,每天都在使用而且起着很大作用。目前固定循环的使用较为广泛,但大多以机床已经定制好的循环为主。如钻孔循环,镗孔循环,攻丝循环等。有的机床也额外开发了一些宏循环,如排孔,矩形,跑道等,这些循环均以宏程序的形式存在,没有进一步定制G代码或M代码。自行开发的不足5%,基本属于空白,有待于我们探究、开发、应用。 Canned cycles are part of the machining center programming and are used daily and play a big role. The current use of fixed cycle is more extensive, but most of the machines have been customized to a good cycle. Such as drilling cycle, boring cycle, tapping cycle. Some machine tools have also developed some macro loops, such as row holes, rectangles, runways, etc. These loops exist in the form of macro programs without any further customization of G codes or M codes. Less than 5% of their own development, the basic is blank, we need to explore, development, application.
