Abstract
Abstract A three-dimensional shape machining laser device for performing three-dimensional machining. The device comprises a teaching box (20) for teaching NC commands, a sensor (43) for detecting the distance between the distal end of a nozzle and a work, a control apparatus (10) which includes command storage apparatus for storing the NC commands, NC command execution apparatus for executing the NC commands, tracing apparatus for controlling the gap between the nozzle and the work to a predetermined value, interrupt control apparatus for interrupting the execution of an NC command program, correction value calculation apparatus for calculating correction command values used for correcting coordinate values, and correction apparatus for correcting command values in accordance with the correction command values, etc. Tracer control is performed during execution of the NC commands, and when an amount of deviation from a path according to the NC commands exceeds a predetermined value, correction values are inserted to correct the path. Alternatively, the NC commands are executed without performing the tracer control. When an amount of deviation of the gap exceeds a predetermined value, correction values are inserted to correct the path. Teaching data can therefore be easily checked for accuracy and corrected, whereby reliable teaching data can be obtained.
