Error standard of laser cutting machine in work
Inlaser cuttingIn the process of mechanism construction, there are many factors that will cause the relative position of the focus and the surface of the processed object to change, including the unevenness of the surface of the processed workpiece, the clamping method of the workpiece, the geometric error of the machine tool, and the deformation of the workpiece. The thermal deformation of the workpiece during processing will cause the laser focus position to deviate from the ideal given position. Some errors are regular and can be compensated by quantitative compensation, but some errors are random and can only be eliminated by online detection and control. These errors are:
1. Laser cutting machine workpiece geometric error
The object of laser cutting is a plate or cover part. Due to various reasons, the surface of the workpiece has undulations, and the influence of thermal effects during the cutting process will also cause the surface of the thin plate parts to deform. For laser processing, the surface of the part will appear uneven when it is covered during the stamping process, which will cause random changes in the position and ideal position of the laser focus and the surface of the processed object.
2. Error caused by laser cutting machine workpiece clamping device
The workpiece processed by the laser cutting machine is placed on the needle table. Due to processing errors, long-term wear of the workpiece, laser burns and other reasons, the needle bed will appear uneven. This non-uniformity can also produce differences between the steel sheet and the laser focus, and random errors between positions.
3. Errors caused by laser cutting machine programming
In the process of laser cutting, the processing trajectory on complex curved surfaces can be fitted with straight lines, arcs, etc. There is a certain error between these fitted curves and the actual curve, which makes the relative position of the actual focus and the target point and the ideal position possible. There is some error in the programmed position of the object surface. Some instructional programming systems also introduce some bias.
The detection and control of laser focus position is one of the key technologies of laser cutting. For fast cutting, the detection accuracy and speed of the focus position will directly affect the control accuracy and processing quality of the focus position. The capacitive sensor has high detection sensitivity and fast response speed. The advantage of a computer system is that it can be linearized to overcome its nonlinearity. The special sensor structure eliminates the influence of plasma cloud and slag spray generated during processing on the detection results, thereby improving its application effect in the laser cutting machine processing system.
