Abstract

The invention discloses a laser measurement compensation method for realizing a five-axis RTCP system. The method comprises the following steps: configuring a laser height acquisition system and a five-axis controller system to synchronously run an executable processing file; virtualizing a sixth axis and a signal thereof beyond five axes, wherein the signal value of the sixth axis is defined as an increment signal capable of describing the motion trail of the fifth axis; preprocessing the laser height data; calculating the offset of the delay between the signal of the sixth axis and the five-axis data; matching five-axis data with laser height data based on the calculated offset of the delay; and compensating and correcting a machining path based on a matching result. According to the laser measurement compensation method for achieving the five-axis RTCP system, accurate synchronization of the laser measurement system and the five-axis controller system can be achieved, compensation for an executed machining path is accurately calculated according to the accurate synchronization, and the efficiency, accuracy and reliability of automatic machining can be improved.

Description

technical field [0001] The present invention relates to the five-axis RTCP (Rotated Tool Center Point)-based laser measurement and compensation processing used in the field of numerical control, in particular to a method based on the analysis and extraction of laser data in three-dimensional space and the acquisition and matching of machine tool paths to form more accurate A new laser measurement compensation method for realizing five-axis RTCP system of machining path control. Background technique [0002] The existing laser data acquisition and five-axis RTCP compensation processing methods, the first is the free-form surface measurement method, which are the traditional contact measurement method, non-contact measurement method, and layer-by-layer scanning measurement method. Compared with the contact measurement method, the non-contact measurement method with laser ranging as an example has obvious advantages. The main disadvantage of contact measurement is that it may d...
