By using this system, detail drawings of these tools and NC program for wire cutting can be directly generated, and the outline shape of designed tool and processing codes can also simulated.

Moreover, the system could quickly, directly and accurately generate not only the detailed drawing of high precision form tools, but also the NC program.

By the integration of numerical result and CNC programming, a new method which advances the efficiency at the CNC machining of arced lath tool is provided.
