摘要： A laser unit capable of suitably updating a correction coefficient for correcting a laser output command for a laser oscillator. Validation of input of an update activation signal for the correction coefficient (F1=1) or waiting is carried out by operation of a display, a keyboard or a switch or by inputting an external signal. Flag F2 indicating automatic running, flag F3 indicating laser beam output and flag F4 indicating a shutter condition are checked. The correction coefficient is set to “1” only when flags F2, F3 and F4 are all equal to zero. Further, a laser output reference command value is outputted and the correction coefficient is updated after a predetermined time. Otherwise, a message indicating a reason for prohibition of update of the correction coefficient is displayed on an indicator, flag F1 is set to zero and the process is terminated.

摘要： A laser unit which has an improved reliability in a measured value of a power correction coefficient used to correct a laser output command. Immediately before the laser oscillator starts discharging after a power supply is turned on, the initial value of a number (or index) for carrying out a warm-up operation is set to zero. A temperature measuring device measures a temperature of a prescribed part of the laser oscillator, and it is decided whether the measured temperature has reached a predetermined temperature. When the measured temperature has reached the predetermined temperature, a normal laser oscillator start processing is executed, and a power correction coefficient is calculated/updated, thereby ending the process. When the measured temperature has not reached the predetermined temperature, the number of times of carrying out a warm-up operation is checked, and the oscillator executes the warm-up operation until the predetermined temperature is obtained within a given number of times. When the number of times of carrying out the warm-up operation exceeds the given number of times, an alarm is displayed to stop the operation of the laser oscillator. Also, an internal discharge carried out to obtain a power correction coefficient may be utilized for the warm-up operation.

A gap amount sensor (43) detects the gap amount between the workpiece and the nozzle. An approach unit (12, 41) causes the nozzle to approach the workpiece to a position suitable for the laser machining. The approach unit performs a first approach operation (12a) for making the nozzle approach the workpiece using the gap amount detected by the gap amount sensor until the gap amount comes to assume a predetermined value, and a second approach operation (12b), after the first approach operation, for causing the nozzle to approach the workpiece until the complete approach without using the gap amount detected by the gap amount sensor.
