Coordinate measuring machine (CMM) dimensional inspection is an integral part of modern manufacturing processes, used to control the production quality of mechanical workpieces. An automatic planning system, linking CAD with CMM, can increase inspection efficiency and effectiveness, reducing or eliminating human influence. Developing a computer aided inspection planning (CAIP) system involves interpretation of part design (geometry and tolerance specifications), representation of inspection actions and their effects on the parts, reasoning about the effects of sequence of such actions, controlling the search and data manipulation, as well as determining details of inspection and programming code for CMMs. In this way it is possible to automatize the different steps involved in a dimensional inspection: determining the measuring points, selecting inspection devices and sensors, determining a detailed inspection sequence, etc. Touch probe selection is one critical step for inspection to be carried out on a coordinate measuring machine.

Abstract
Coordinate measuring machine (CMM) dimensional inspection is an integral part of modern manufacturing processes, used to control the production quality of mechanical workpieces. An automatic planning system, linking CAD with CMM, can increase inspection efficiency and effectiveness, reducing or eliminating human influence. Developing a computer aided inspection planning (CAIP) system involves interpretation of part design (geometry and tolerance specifications), representation of inspection actions and their effects on the parts, reasoning about the effects of sequence of such actions, controlling the search and data manipulation, as well as determining details of inspection and programming code for CMMs. In this way it is possible to automatize the different steps involved in a dimensional inspection: determining the measuring points, selecting inspection devices and sensors, determining a detailed inspection sequence, etc. Touch probe selection is one critical step for inspection to be carried out on a coordinate measuring machine. The present paper reports the preliminary study and the prototypical realisation of an expert system to generate touch probe configurations.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
