    Default How to Calculate pitch when tornado milling pockets with mazatrol

    Hello,
    Iím new to mazak and donít have any real experience. So any constructive criticism is appreciated.

    Iím using a mazak pallet tech system with a nexus controller.

    The idea is to spiral cut an internal pocket.

    I need to calculate the pitch. Itís explained to me as the corkscrew action of the mill as it spirals down cutting the round pocket or socket.

    How do I get numbers that make sense?

    I didnít add material or sizes because Iím trying to find out how to calculate the number.

    Thanks

    The pitch is the distance traveled in Z in one complete rotation. That value is whatever will give you the desired result.

    Using a downward path of 5 degrees would be figured by:
    P=0.137*(D-d) where D is the diameter of the hole and d is the diameter of the end mill. If this is too aggressive then use a smaller constant. A few trials with a scrap piece of material should yield a constant that works for your situation.
