This procedure determines the distance between the plane of the B-Axis platter and the A-Axis centerline on tilting rotary products. Some CAM software applications require this offset value.

A-Axis Center-of-Rotation Illustrated Procedure

  1. Jog the A Axis until the rotary platter is vertical. Attach a dial indicator to the machine spindle (or other surface independent of table motion) and indicate the platter face. Set the dial indicator to zero.
  2. Set the Y-Axis operator position to zero (select the position and press ORIGIN).
  3. Jog the A Axis 180°.
  4. Indicate the platter face from the same direction as the first indication: Hold a 1-2-3 block against the platter face. Indicate the face of the block that rests against the platter face. Jog the Y Axis to zero the indicator against the block.
  5. Read the new Y-Axis operator position. Divide this value by 2 to determine the A-Axis center-of-rotation offset value.
