摘要： The invention provides a machining method and a machining apparatus in which the machining productivity and the machining quality of the machining apparatus can be improved. Prior to machining, an NC control unit makes an X-axis drive unit move a table based on examination conditions specified in advance. Thus, the NC control unit obtains a stabilization time required from the command-reach time of a poisoning command and till the stabilization of position response of the table within a predetermined allowable range. Likewise, for means for moving a drill in a Y-axis direction, the NC control unit obtains a stabilization time required till the stabilization of position response within a predetermined allowable range. At the time of machining, the drill is moved in a Z-axis direction to cut into a printed wiring board as soon as the obtained stabilization time has passed.
