Method For Improving Cutting Error Of Plate And Tube Integrated Laser Cutting Machine

The plate and tube integrated laser cutting machine is an intelligent cutting equipment for round tubes, square tubes, special-shaped tubes and planes. It has an automatic control system and can achieve high flexibility, high precision, and multi-directional cutting effects. The individualization of modern industrial manufacturing The traditional pipe cutting machine can no longer meet these standards, and this equipment, as a new generation of pipe and flat cutting equipment, has improved in technology and performance.

If there is a deviation in the processing process, the product may be scrapped, resulting in different degrees of loss, so how to improve this cutting error?

1 Workpiece geometric error

Due to various reasons, the surface of the workpiece is uneven, and heat is generated during the cutting process. At this time, the surface of the thin plate part is easily deformed. Because the surface of the workpiece is not flat, the position of the workpiece surface and the laser focus will occur. random changes in position.

2 The thickness of the cutting material exceeds the standard

If the plate of the workpiece is too thick, the equipment will be more laborious during the cutting process. Under the condition that the workpiece is guaranteed to be cut off, there will be errors in the accuracy of cutting. Taking 3000w as an example, the equipment can cut plates with a thickness of less than 20. The easier it is to cut the sheet, so be sure to determine the thickness of the sheet when cutting.

3 An error occurs during programming

In the process of machining the workpiece, because the machining trajectory is fitted by straight lines, arcs, etc., there is an error between these fitted curves and the actual curve, because these errors lead to the relative position of the actual focus and the workpiece surface and the ideal programmed position An error occurred.

In the process of use, there are many reasons for the change of the focus and the corresponding position of the workpiece surface, which is also related to the smoothness of the workpiece surface. The thermal deformation during the cutting process causes the laser focus and position to deteriorate. These random errors are unavoidable, and the error can only be reduced through control, thereby improving the working accuracy of the laser cutting machine.
