Abstract
This disclosure concerns a method for selecting a tool-path strategy in a material processing operation. The geometry of a work piece (34) and the contact patch (36) of a tool are determined and used to define a tool-path boundary (30,32). A number of different possible tool-paths (38,40,46) are then simulated within the tool-path boundary (30) and the most preferred tool-path (38,40,46) is selected based on predefined requirements.
Claims14
A method for selecting a tool-path strategy in a material processing operation, the method comprising:
- a) determining a geometry of a work piece to be processed and a contact patch of a tool on the work piece;
- b) defining a tool-path boundary based on the geometry of the work piece and the contact patch of the tool;
- c) simulating a number of different possible tool-paths within the tool-path boundary;
- d) calculating a material removal map for each simulated tool path;
- e) calculating a process time for at least a selection of the simulated tool paths;
- and
- f) selecting a preferred tool-path based on a predefined requirement for material removal and/or process time.
