When Error Occurred in The Process of Pipe Cutting

There are many problems in the use of laser pipe cutting machine, including the error in the process of laser pipe cutting, laser pipe cutting effect is not good. So how do these mistakes happen? The following laser pipe cutting machine manufacturer will answer your questions.

The geometric error of the workpiece, due to various reasons, the surface of the processed object is not smooth, and heat will be generated during the cutting process. In this way, the surface of the metal plate is easy to deform, and due to the uneven surface, laser focusing and surface will also be generated. The position and ideal position of the surface of the object to be treated vary randomly.

Material cutting thickness exceeds the standard: material cutting thickness exceeds the standard. Take 3000W as an example: The thickness of the plate can be cut by the laser pipe cutting machine is less than 20. The thinner the sheet, the easier it is to cut, and the better the quality. If the sheet is too thick, the laser tube cutter will be more difficult to cut. In the case of guaranteed cutting, there will be errors in the processing accuracy, so the thickness factor of the plate must be determined.

Programming error: In the processing process of the laser tube cutting machine, the processing path on the complex surface is fitted by a straight line, an arc, etc. There are errors between these fitted curves and the actual curves.  These errors become the actual focus, and there is an error between the relative position of the machined target surface and the ideal programming position. Some instructional programming systems also introduce biases.

Focus position error when laser cutting pipe: In the cutting process of laser cutting machine, there are many factors that will change the relative position between the focus and the surface of the object to be processed, which is also related to the surface smoothness. The shape clamping method of the processed product, the geometric error of the machine tool and the long-term load of the machine tool will be deformed. Thermal deformation of the workpiece during machining will cause the laser focusing position to deviate from the desired given position (programmed position).
