Background

With the existing method of directing machining in the processing program (NC program), it is not possible to realize intelligence of the machine tool. Therefore, on this theme we are developing innovative intelligent technology of machine tools that converts from machining by NC program to a method that calculates the tool position and tool posture during machining and sequentially directs it(Figure 1).

This makes it unnecessary for a lot of labor required to create NC program and it will be able to machining with ease as with 3D printers. In addition, it is possible to reduce production lead time and realize an autonomous decentralized factory.

Goals

1. To prototype an innovative intelligent NC machine tool unprecedented in the world capable of machining from three dimensional CAD models of materials and products without creating an NC program.
2. Implement adaptive control of cutting force to realize improvement in machining efficiency and avoidance of machining troubles.
3. Improve machining accuracy by correction machining based on machine tool measurement.

Implementation contents
