ABSTRACT:
A method for setting a working origin for a rotary tool in contact with a work piece to be machined, having: applying to a main spindle which holds the rotary tool, with a tip of a cutting edge of the rotary tool in contact with an outer surface of the work piece fixed to a work table, a load torque to such an extent that the rotary tool is not caused to be rotated; applying the load torque to the main spindle, and moving either the work table or the main spindle in a jog feed in a direction of any one of feed shafts such that the tip of the cutting edge is moved away from the outer surface along an axial direction of the rotary tool or in the direction orthogonal to the axial direction; and setting a coordinate at the moment when the main spindle starts rotation as a working origin of the jog feed in the direction of the any one of the feed shafts.
