A Method to Calculate Tool Accessible Domain Based on the Point Model for the Multi-axis CNC Machining

摘要：

　　This paper puts forward a kind of method which can calculate tool accessible domain for tool axis optimization in the complex curved surface multi-axis machining.At first,the point model has been construced on the base of constrained surface.The second,based on any possible direction of tool axis vector of a given cutting contact point,the distance between a point and a line is used to decide whether occurs collision and interfence.The third,two angles related with cutter-axes vector is definied.The regulation of tool accessible domain can be implemented by getting the boundary of the discrete points in the coordinate planes.Finally,a tool has been developed to calculate tool accessible domain,and an example is given to verify the effectiveness of the method.
