NC DATA FORMING METHOD AND WORK MACHINE CONTROL DEVICE

PROBLEM TO BE SOLVED: To provide an NC data forming method and a work machine control device which can easily form an NC data to facilitate its change. SOLUTION: A work machine control device 41 comprises a pattern data memory 20 storing a pattern data, a work condition data memory 22 storing a work condition number in each work kind and storing a work condition control data corresponding to each work condition number, line length discriminating data memory 23 storing a threshold value for obtaining a work kind of a pattern data, and an NC data memory 24 storing an NC data obtained based on a data stored in these work condition data memory 22 and line length discriminating data memory 23 and the pattern data 24. Relating to a laser work machine 60, the NC data is output. In the laser work machine 60, a work kind input part is provided, and an input work kind data is fed as a data for selecting the pattern data and the work condition data memory to the work machine control device 41. In the laser work machine 60, based on a work condition control data contained in the NC data fed from the work machine control device 41, work control is performed.
