Research and Analysis Based on Three-dimensional Precision Inspection Process Planning Technology

Abstract Three-dimensional precision inspection has the characteristics of digitization, completeness, and timeliness. The manufacturing industry needs to research and improve the existing inspection process planning technology. Carried out research on the key technology of three-dimensional inspection process planning, including inspection information extraction, inspection point planning, path planning, etc., compared and analyzed the offline inspection technology represented by the coordinate measuring machine and the online inspection technology represented by the machining center. Studied and analyzed the system architecture, main functional modules of process planning software tools for these two types of inspections; finally, it looks forward to the future development trend.
