Process Design Technology” has a mechanism to make customer's standard such as various pallets and templates which contains customer's know-how. Easy to operate will enable beginner to create NC data quickly. Roughing consider the stock model cut by previous process. It enables to create more efficient cutting path to cut the rest of material. Create semi rough path applied to the rest of material after rough process. Previous tool can apply ball and radius type. Compare design model and cut model, and display color map depend on volume of rest material. Green : design and cut model is same Blue : Rest material Red : Gauge Cutting Simulation function can show the following result. -G00 interference -Interference of shank and holder -Check effective tool length -Specify rest material by comparison design model and cut mod
