Abstract
A controller of a laser processing apparatus includes a processing trajectory storage section, a thickness storage section (TSS), a limit processing depth storage section (LPDSS), a pass number storage section (PNSS), a spot overlap rate storage section, and a selecting section. The controller calculates a processing width by multiplying, by a spot diameter, a value obtained by dividing a thickness stored in the TSS by a limit value stored in the LPDSS, and calculates the number of passes of a pulsed laser beam (LB) to be applied to a section width-wise by multiplying the value obtained by dividing the thickness stored in the TSS by the limit value stored in the LPDSS by the number of passes stored in the PNSS, and multiplying a result by a number of spots determined from the spot diameter of the LB, the overlap rate of the spots, and the processing width.
