Machining process modeling Coordinate systems

The scenario of the entire computer controlled machining system is shown by Figure 6-11. The machine tool and machining process are described in a model space with coordinates Ym, and Zm- For programming, a local coordinate system is applied with coordinates Xp, Yp, and Zp. The machine tool has five simultaneously controllable axes X, Y, Z, Q. Part coordinates are transformed into controlled coordinates automatically. The... 

Simulations for checking of the feasibility of a cycle process input information about the controllable axes, and the relationship between axial movements and volumes moving in the working space of the machine tool. For this purpose, a simplified model is appropriate. Figure 6-23 introduces such a model by the example of a typical milling machine. In this example, the directions of the model space coordinates and the controlled axes are the same. In the case of a flexible manufacturing system with several machine tools in the model space, the directions of the controlled axes are described by vectors. The simplified model describes the direction and extent of slide movements, the structure of the machine tool.
