Patent ID: 7370796

Claim:
A laser processing system comprising: a laser processing machine for operating along an inherent control axis; an axis driving section driving said control axis of said laser processing machine; a laser oscillator supplying a laser beam to said laser processing machine; a control unit controlling said axis driving section and said laser oscillator; and a transfer line connecting said axis driving section and said laser oscillator to said control unit in a daisy-chain mode; said control unit comprising: a data preparing section preparing, from a given laser processing program, motion data commanded to said axis driving section and laser output-condition data commanded to said laser oscillator; a data converting section converting said motion data and said laser output-condition data, prepared by said data preparing section, into serial data including said motion data and said laser output-condition data described in a time-series fashion, based on a communication data format common to said axis driving section and said laser oscillator; and a data transmitting section transmitting said serial data, obtained by said data converting section, to said transfer line at a predetermined command cycle common to said motion data and said laser output-condition data included in said serial data.
