What caused the error in the metal laser cutting machine?

There are many problems in the use of metal laser cutting machines, including errors in the process of laser cutting, poor laser cutting effects, etc. So how do these errors occur?The following editor will come to answer for you.

Cutting sample

　　1. Geometric error of workpiece

　　Due to various influences, the surface of the processing object is uneven, heat will be generated during the cutting process, so that the surface of the thin plate part is easily deformed, due to the uneven surface, the laser focus the surface of the object to be processed will also be generated. The ideal position changes randomly.

　　2. The cutting thickness of the material exceeds the standard

　　The thickness of the cutting material exceeds the standard.In an example 3000W: laser cutting machinecan cut the sheet thickness in a thickness of 20 less, the thinner the plate, the easier it cut,

　　The better the quality.If the plate is too thick, the laser cutting machine will be difficult to cut. Under the condition of ensuring the cutting, the processing accuracy will be error, so the thickness factor of the plate should be determined.

　　3. Errors caused by programming

　　Duringthe processing of the fiber laser cutting machine, the processing trajectories on complex curved surfaces are fitted by straight lines, arcs, etc. These fitting curves actual curves have errors. These errors make the relative positions of the actual focus the surface of the processing object The ideal programming position produces errors.Some teaching programming systems also introduce some deviations.

　　4. Generation of focus position error during laser cutting

　During the cutting process of the fiber laser cutting machine, there are many factors that change the relative position between the focus the surface of the object to be processed, which is also related to the surface smoothness of the processed product, the clamping method of the workpiece, the geometric error of the machine tool, the long time of the machine tool. The deformation of the load the thermal deformation of the workpiece during the machining process will cause the laser focus position the ideal given position (deviations occur).

　　For these random errors can be avoided, only through online detection control to reduce the generation of errors, thereby improving the working accuracy of the fiber laser cutting machine.
