Abstract
Coordinate Measuring Machine (CMM) inspection planning is an activity performed by well-trained operators, but different measurement techniques, using the same data analysis algorithms yield in different measurement results. This is a well-recognized source of uncertainty in coordinate measurement. A CMM, provided with an automatic inspection planning (CAIP) system, permits to implement more accurate and efficient operating procedures and to fit higher quality assurance standards and tighter production timings.In this paper we present a frame of a CAIP system, able to deal with almost all the decisional stages of CMM inspection. Moreover, original approaches have been developed and presented in inspection feature selection, part set-up, probe configuration, and path planning.
Highlights
The growing request from industry of both a concurrent-integrated manufacturing environment and a certified production causes inspection to have a key role to reach manufacturing reliability and safety

Summary
The growing request from industry of both a concurrent-integrated manufacturing environment and a certified production causes inspection to have a key role to reach manufacturing reliability and safety. A computer aided inspection planning system aims to reduce the measurement time and uncertainty It allows to automatically plan all the operations concerning with CMM inspection of mechanical parts by means of optimization techniques. It gets information from a geometric model representation of the part, enriched with tolerance specifications, and makes decision without human intervention, in order to generate a complete CMM part program. More recent works represent a first attempt to integrate computer aided inspection with CAPP/CAM for improving the machining process and controlling machining quality [11]-[12] They are developed for free form surfaces. The aim to overcome those limits is the basis to develop the present work
