Abstract

The invention discloses a laser measurement and compensation method for realizing a five-axis RTCP system. The method includes: configuring a laser height acquisition system and a five-axis controller system to synchronously run an executable processing file; virtualizing a sixth axis other than the five axes And its signal, the signal value of the sixth axis is defined as an incremental signal that can describe the motion trajectory of the five-axis; preprocess the laser height data; calculate the offset of the delay between the signal of the sixth axis and the data of the five-axis; The offset based on the calculated delay matches the five-axis data and the laser height data; based on the matching result, the processing path is compensated and corrected. According to the laser measurement compensation method for realizing the five-axis RTCP system of the present invention, it is possible to realize the precise synchronization of the laser measurement system and the five-axis controller system, and accordingly accurately calculate the compensation for the executed processing path, which helps to improve automatic processing efficiency, precision and reliability.

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...
