In the process of mould processing, cutting tool, the electrode loss after grinding and polishing surface caused by the error precision, often is the most not easy to see, at present, the mold testing equipment is mainly three coordinate measuring machine, three coordinates measuring machine price is quite expensive, need to do precise positioning fixture to be measured objects, the process cumbersome and time-consuming, laborious, and the use efficiency is low.
Today, with the color error analysis diagram to present full size precision of computer aided testing specification PolyWorks of CAV spread quickly all over the world, widely used in automobile, 3 c mobile phone producers, and quickly popularized to supply chain upstream and downstream, it changes the traditional method of product quality inspection, rapid scanning, the reverse scan measurement object into dense point cloud data, to operate and convenient detection PolyWorks software for automatic registration, comparative analysis, and then use different colors to show the whole workpiece error values, let a person be clear at a glance to master in time the product quality status, and automatically generate reports, to achieve the effect of full product testing.
Figure 1 is PolyWorks CAV application process, we have two ways to test the mold process, one is direct detection of mould, the other is by testing the finished product to achieve the objective of the test mould, its process is: in the reverse scan way to finished product or mould kernel, cavity, the slider scanned into point of key parts such as data, into the PolyWorks in counterpoint to compare with standard CAD file detection, through the color error analysis diagram, you can be clear at a glance to master the whole domain size, fast accurate demonstrate the quality of the mould.
