Embodiment Construction
[0021] The present invention will be further described below in conjunction with embodiment.
[0022] The MTX system used in the embodiment of the present invention was purchased from Bosch Rexroth, and its full name is IndraMotionMTX system, which can be obtained through conventional commercial channels.
[0023] refer to figure 1 and figure 2 , a cutting head height control method for a laser cutting machine, the laser cutting machine is provided with an MTX system, specifically comprising the following steps:
[0024] Step 1. The MTX system controls the cutting head of the laser cutting machine to drop rapidly;
[0025] Step 2. The cutting head descends to the detection height area of the height sensor. The MTX system receives the signal value fed back by the height sensor and the Z-axis encoder and processes it quickly, and then outputs the command value to control the cutting head to decelerate;
[0026] Step 3. Repeat step 2 until the cutting head reaches the set h...

The invention relates to the field of laser processing, in particular to a method for controlling the height of a cutting head and a laser cutting machine, comprising the following steps: the MTX system controls the rapid descent of the cutting head of the laser cutting machine; the cutting head descends to the detection height area of the height sensor, and the MTX system Receive the signal value fed back by the height sensor and the Z-axis encoder and process it quickly, and then output the command value to control the deceleration of the cutting head; repeat the above steps until the cutting head reaches the set height and stops accurately. After the cutting head descends, the MTX system controls its rapid descent, greatly reducing the travel time; when the cutting head enters the detection height area, the MTX system quickly processes the feedback signal value, and then feeds back the signal to control the cutting head to decelerate Compared with the traditional CNC system, the processing efficiency and control precision of the MTX system are higher. Its precise and stable control avoids the problem of the cutting head moving and hitting the board, thus achieving a fast and stable cutting head from falling to stopping. Effect.
Description
technical field [0001] The invention relates to the field of laser processing, in particular to a method for controlling the height of a cutting head and a laser cutting machine. Background technique [0002] At present, many domestic and foreign laser flat cutting machines have corresponding height control schemes according to the feedback value of their height sensors and different numerical control systems, to control the cutting head to descend steadily from a high place to a position at a specified height from the board surface. However, many control schemes currently on the market have the defect that the cutting head's descending speed is slow or the descending speed is fast but the control is unstable, so it is urgent to improve. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a cutting head height control method and a laser cutting machine with fast descending speed and stable control in view of the abov...
