Appearance of cutting tool geometry, the influence of appearance of spare parts geometry and process, decide the geometry of end item, safe geometrical tool, reduce the effect of any processes as far as possible, to a product be being rolled out smoothly is crucial. The capability of initiative tool is higher, call in cost will exceed the line on fast ground. A successful tool attestation process includes tool of CAD test and verify, check the repeatability of tool spare parts, check CAD of the spare parts inside the tool finally. The method of these effective will promote the product of top quality to the market ahead of schedule, be extensive investment plan as a result reclaim. Change direction as more and more tool suppliers lighter, agile robot assembles tool to make directive station, be not being stabilized however is a reality. Stride the coordinate system of Zhuo Nuo's unique float part, although they may be in not stable area, but also can measure, can move in measuring a process even. CNC Milling
