Vector analysis of the accuracy of the layout of automatically replaceable systems for delivering laser radiation to the processing zone

The paper discusses the methodology for calculating the errors in the layout of systems for delivering laser radiation to the processing zone on the example of laser modules of CNC machines. A vector analysis of the accuracy of individual blocks in the composition of such laser modules is performed. A technique is proposed for calculating the error in positioning a laser beam depending on the number and use cases of blocks and their noncollinear axes in the laser module. Errors associated with the laser module used for private technical design, a set of blocks and their kinematic relationships, are considered. The factors affecting the error in the arrangement of transmission devices in the laser radiation processing zone are established. The proposed methodology allows us to solve both the direct and inverse problems of calculating the errors arising during the arrangement of transmission devices in the laser radiation processing zone.
