    Hello guys

    A few weeks ago I change my firm and now have to write programs myself... (I worked on series before) under S840C. I have a few questions regarding the commands:

    1. what does the command G451 mean when SRK is switched on (turning)?

    2. What’s the purpose of the command precision stop(apart from creating sharp changeover)
    Is it useful to probe a fit with precision stop?

    3. How do you program with powered tools e.g. to create a pitch cycle holes?

    Would be nice if anybody could help me out!

    Kind regards

    Re: questions: G commands

    Friends, tell me how to properly rotate the spindle of the sinumerik 840C turning and milling machine in the milling mode by more than 450 degrees. And at the same time indicate to him the direction of rotation?
