Abstract

PURPOSE:To eliminate the measuring action of a worker and to unman a laser beam machining by operating the plate thickness of a work by a work plate thickness detecting means from the torch position at the time when the work detecting means detects the work. CONSTITUTION:The arithmetic means of the present position of the torch 2 of a shaft driving control part 7, etc., is provided and the work detecting means of a profiling device 3, etc., is provided so as to interlock with the movement of the torch 2. The present position of the torch 2 is operated by said arithmetic means 7, based on the signal S1 outputted in case of detecting the work from the work detecting means 3. The plate thickness of the work is operated by the work plate thickness arithmetic means of a profiling control part 6, etc. from this current position of the torch 2. The prescribed laser beam machining is performed by projecting a laser beam with the control of the torch 2 by its driving based on this plate thickness.

Since the laser processing machine has the above configuration, during processing, when a workpiece 10 of a predetermined thickness is mounted on the table 11 as shown in FIG. 9 is driven to move 1 and 2 in the direction of the arrow, that is, in the Z-axis direction. When the torch 2 moves in the inward direction, the profiling device 3 also moves in the inward direction, and the stylus 3a of the profiling device 3 comes into abutting contact with the surface of the workpiece 10, as shown in FIG. Then, since the stylus 3a is pressed in the direction B by the workpiece 10, the profiling device 3 determines that the stylus 3a has come into contact with the surface of the workpiece 10, and outputs a signal S1 to the profiling control section 6. In response to this, the profiling control section 6 causes the shaft drive control section 7 to transmit the torch 2.
It instructs the torch 2 to stop moving in the incoming direction, and also instructs the calculation of the current position of the torch 2. Therefore, the shaft drive control unit 7 immediately stops driving the drive morph 9 and stops the movement of the torch 2 in the incoming direction, and the position output from the transducer 13 at every predetermined rotation angle of the drive motor 9. The amount of rotation angle of the drive motor 9 is determined from the pulse PS, and from this value, the current movement ratio IIIBI of the tip of the torch 2 in the Z-axis direction from the machine origin MZP is calculated and outputted to the profiling control section 6. The profiling control unit 6 moves the workpiece 1 according to the following formula from the calculated movement ratio 111BI.

In this way, when the plate thickness t of the workpiece 10 has been calculated from equation (1), the profiling control unit 6 outputs the calculated plate thickness t to the main control unit 15, and the main control unit 15 outputs the calculated plate thickness t. Based on this, the movement mode of the torch 2 in subsequent processing is determined, and the torch 2 is driven and controlled via the axis drive control section 7, and the laser beam 16 is emitted from the torch 2 to the workpiece 10. A predetermined process is performed on the workpiece 10.
