Abstract

The invention discloses a multi-mirror laser precision splicing calibration method, which is specifically implemented according to the following steps: Step 1, building a multi-mirror laser precision splicing calibration table; Step 2, making a standard calibration plate and adjusting the standard calibration plate; Step 3, Scan the galvanometer to eliminate the standard deviation; step 4, extract the point deviation of the galvanometer, and generate the standard deviation matrix table of the equipment to complete the splicing correction of the multi-galvanometer precision. The invention solves the problems in the prior art that it is difficult to get in place at one time during the precision correction process of multi-vibrating mirror equipment, takes a long time and has poor splicing precision.

Description

technical field [0001] The invention belongs to the technical field of metal powder laser melting and additive manufacturing, and in particular relates to a multi-mirror laser precision splicing calibration method. Background technique [0002] Metal powder laser melting additive manufacturing technology can form metal parts with high complexity and precision. At this stage, metal powder laser melting additive manufacturing technology mostly uses galvanometers as optical path control equipment. It is difficult to correct the accuracy of multi-galvanometer equipment at one time, and multiple calibrations are required, which consumes a lot of time and energy, and there is also the problem of poor splicing accuracy. Contents of the invention [0003] The purpose of the present invention is to provide a multi-galvanometer laser precision splicing calibration method, which solves the problems in the prior art that it is difficult to complete the precision calibration of multi-...
