Laser cutting machine

摘要

A laser cutting machine cancels an alarm which is produced by a remote sensor during a penetration action, or cancels the alarm during a first movement after a penetration action until a movement takes place over a predetermined distance, or cancels the alarm in a block which has no movement, or keeps the alarm inoperative from the start of a penetration action until a movement takes place over a predetermined distance after the penetration action, or cancels the alarm from a point which lies at a predetermined distance in front of a cutting-action completion point up to the cutting-action completion point, or leaves the alarm inoperative from a point which lies at a predetermined distance from the cutting-action completion point until a movement takes place over a predetermined distance after arrival at the cutting-action completion point, or cancels the alarm over a predetermined travel distance in a predetermined motion command block of the NC program, as a result of which the laser cutting machine can prevent the cutting action from being stopped by an unnecessary alarm which is caused by the alarm signal of the sensor as a result of scattered or collected spatter, the effect of a plasma, inclination of a workpiece or contact with a portion of the workpiece which has been blown away at the cutting-action completion point, ...
