KG 252 Chapter 6 Universal Measuring Machine -for Checking Tooling In many machining circumstances the tool s profile becomes part of the contoured form for the final machined component. Therefore it is important after the milling cutter has been multi-axes ground to a desired profile that this form is rigorously inspected as the cutter s rotated-shape will become part of the final workpiece geometry. In order to establish this ground complex cutter profile special-purpose universal tool measuring machines have been developed - see Fig. 135. Such multi-axes machines have a range of functions from simply manually-checking elementary cutter forms to that of fully-automatic assessment of a multi-faceted form cutters. The machine illustrated in Fig. 135 is based upon sound kinematic principles equipped with three linear axes and two rotary axes Fig. 135c . The high-precision linear guidance motions are controlled by re-circulating ballscrews36 these being propelled by servo-motors. The incident light measuring technology associated with this type of machine is quite sophisticated Fig. 135b offering 3-D image processing to permit threedimensional geometrical cutter elements to be fully-automatically measured - using a proximity method of assessment. The camera lens and the LED incident light in combination with its automatically dimmable segments have been designed to operate with ground or eroded PCD cemented carbide and HSS tooling. Special-purpose ambient light filters and an automatic lighting calibration function ensure that .
