Modern measuring equipment integration (tactile probes and scanners) on CNC machining systems enables the measuring of machining parts directly on the machine, known as on-machine inspection. In on-machine inspection systems tactile and optical probes are used, however, primarily because of the data acquisition speed, it is expected that the non-contact devices (scanners) will take over the primacy. These measuring systems as a result of measuring include a point cloud that requires software processing and generating surfaces, then comparing it to a CAD model with the goal of obtaining measurements. The obtained inspection report should point out the following activities: finishing the part without taking it off the machine or taking a part off the machine and the next processing on other machines, or final control. This paper gives the description of contact and non-contact devices that are used in on-machine inspections, lists the principles and software tools that are used in the acquisition and data processing, and listing the basic advantages and disadvantages. In examples the inspection of prismatic part shoots obtained by milling on the CNC machining center is shown. [ABSTRACT FROM AUTHOR]
