Summary: | PROBLEM TO BE SOLVED: To perform laser machining which generates neither vibration nor a machining shape error at the time of shaft movement by deciding a shaft movement feed kind when the shaft movement is performed and switching and using a feedfoward coefficient matching the decision result. SOLUTION: A program for automatic operation is read in from a program storage part 3 for automatic operation and analyzed by a program analyzing process part 2 to divide the program into execution blocks and a shaft movement feed deciding process part 4 decides which of machining feed movement and fast forwarding movement the shaft movement feed kind is. When the shaft movement feed kind is the machining feed movement, a plate thickness deciding process part 8 and a machining feed operation mode deciding process part 9 decide a plate thickness kind and a machining feed operation mode and a machining feed process part 7 reads in a feedforward coefficient for machining feed corresponding to those decision results. For fast-forward movement, the plate thickness deciding process part 8 decides the plate thickness kind and a fast-forward deciding process part 5 reads in the fast-forwarding feedforward coefficient corresponding to the decision result. |
