Laser machine and controlling method of laser machine

摘要

A laser machine includes a laser oscillator, a cooler for cooling the laser oscillator, and a control unit for controlling the laser oscillator and the cooler. The control unit includes a controller that stops base discharge of the laser oscillator at a time when a specified time has elapsed from a stop of laser light emission by the laser oscillator. According to the laser machine, since base discharge of the laser oscillator is stopped after the specified time has elapsed from the stop of laser light emission, wasteful energy (power) consumption of the laser oscillator in a standby state can be restricted.

主权项

1. A laser machine that operates in one of a standby state of a normal mode, a first energy-saving mode and a second energy-saving mode, in which energy consumption in the first energy-saving mode is lower than energy consumption in the standby state of the normal mode, and energy consumption in the second energy-saving mode is lower than the energy consumption in the first energy-saving mode, the laser machine comprising:
a laser oscillator; a cooler that cools the laser oscillator; a controller that controls the laser oscillator and the cooler, to transfer the laser machine among the standby state of the normal mode, the first energy-saving mode and the second energy-saving mode, wherein the controller transfers the laser machine from the standby state of the normal mode to the first energy-saving mode, by stopping a base discharge of the laser oscillator, when a first specified time has elapsed from a stop of laser light emission by the laser oscillator, and wherein the controller transfers from the first energy-saving mode to the second energy-saving mode, by reducing, without eliminating, an amount of laser gas supplied to the laser oscillator, after a second specified time has elapsed from the time when the base discharge of the laser oscillator stops.
