Computer-Aided Inspection Planning (CAIP) is an important module of modern dimensional measuring instruments, utilizing the CAIP for machined parts inspection is an important indication of the level of automation and intelligence. Aiming at the characteristic of visual inspection, it develops a CAIP system for vision-based On-Machine Measurement (OMM) based on a CAD development platform whose kernel is Open CASCADE. The working principle of vision-based OMM system is introduced, and the key technologies of CAIP include inspection information extraction, sampling strategy, inspection path planning, inspection codes generation, inspection procedure verification, data post-processor, comparison, and so on. The entire system was verified on a CNC milling machine, and relevant examples show that the system can accomplish automatic inspection planning task for common parts efficiently.
