Problems solved by technology

[0002] When the CNC machine tool (Computer numerical control, CNC) processing machine is processing the product, due to the problem of processing the incoming material, the inconsistent thickness of the incoming material will lead to inconsistent processing in the Z direction. In addition, the CNC machining clamping fixture cannot guarantee the accuracy with the CNC machining spindle. The normal vector is absolutely vertical, which is easy to cause large processing errors, so that the thickness of the processed products is inconsistent

Abstract

In a method for compensating step value of a processing product placed on a machining device using a computing device, a machining tool of the machining device is controlled to be moved to each benchmark point in sequence. Actual coordinate values of each benchmark point is calculated by a laser detection device of the machining device. The acquired actual coordinate values are fitted to be a benchmark plane. New coordinate values of each machining point in a machining program is acquired by rotating each of the machining points to the benchmark plane. The machining tool is controlled to move to each machining point according to the calculated new coordinate values and an actual z coordinate value of each machining point is acquired using the laser detection device. The step compensation value in Z-axis of the each machining point is calculated and transmitted to the machining device.

Description

technical field [0001] The invention belongs to the field of gap compensation, in particular to an internal gap compensation system and method of a processing machine. Background technique [0002] When the CNC machine tool (Computer numerical control, CNC) processing machine is processing the product, due to the problem of processing the incoming material, the inconsistent thickness of the incoming material will lead to inconsistent processing in the Z direction. In addition, the CNC machining clamping fixture cannot guarantee the accuracy with the CNC machining spindle. The normal vector is absolutely vertical, which is easy to cause large processing errors, so that the thickness of the processed products is inconsistent. Contents of the invention [0003] In view of the above, it is necessary to propose a system and method for compensation of the gap in the processing machine, which can perform precision compensation for the gap of the product to be processed in the Z d...
