LASER BEAM MACHINING APPARATUS WITH HIGH-SPEED POSITIONING FUNCTION |
摘要 |
When an operation is performed in a direction (Z-axis direction) in which a machining head is brought closer to workpiece, a numerical controller that controls a laser beam machine avoids a collision of the machining head with the workpiece by switching to gap control when a gap sensor detects a gap amount between the machining head and the workpiece. At this point, whether to perform the operation to bring the machining head closer to the workpiece by gap control using a detection value of the gap sensor or by moving the machining head to a position determined by parameters can be selected using a mode switching unit. |

1. A laser beam machine comprising:
a gap sensor that detects a gap amount between a machining head and workpiece; a gap control axis controlled such that the gap amount during machining is maintained constant based on the gap amount detected by the gap sensor; and a machining feed axis that moves the machining head relative to the workpiece such that the machining head moves along a machining shape, the laser beam machine, further including: a workpiece detection unit that moves, when the machining head is moved from a machining end point to a next machining start point, the gap control axis by a predetermined amount in a direction in which the machining head moves away from the workpiece, at the machining end point, and then detects presence of the workpiece based on a signal from the gap sensor when an operation to bring the machining head closer to the workpiece is performed; and a gap control unit that controls the gap control axis using gap control when the workpiece is detected by the workpiece detection unit. |
