    1 1. Overview For the machine having a rotary axis or a tilting axis, if there is a difference between the rotation/tilting center and programming zero, the programming zero position varies with the angle of rotation or tilting. The fixture offset function compensates this variation by rewriti...

    4 6. Method of Determining Pivot Distance through Actual Machining (Example) The procedure below shows the method of determining the pivot distance. (Read the following steps while referring to Fig. 1.) Here, the tilting angle is set to 0° (A0) when the rotary table disk plate is facing up. 1)...
