LASER MACHINING APPARATUS, LASER MACHINING METHOD, MACHINING CONTROL APPARATUS AND MACHINING CONTROL METHOD

摘要

A machining control apparatus (103) controls a machining table, which fixes the bottom surface of a work by suction by means of a suction hole, and a laser machining mechanism (101A) for making a hole on the work by irradiating the work with a laser beam. The machining control apparatus is provided with an extracting section (16) which extracts a machining hole which is to be positioned on an upper side of a suction area of the machining table; and a first time machining hole setting section (14), which sets, as holes to be machined for a first time, the machining holes other than the machining hole extracted by the extracting section (16) from among the machining holes to be machined. The machining controls apparatus controls the laser machining mechanism (101A) to perform the first time hole making machining.
