Abstract
A cutting method in which a workpiece is cut on the basis of a plurality of tool paths parallel to one another into a shape having a corner that protrudes outward. A machining step for machining the workpiece on the basis of one tool path and a moving step for moving to the starting point of the next machining step after the completion of the one machining step are repeated. In the machining step, a cutting step for cutting the workpiece in the one tool path and a removing step for removing a burr by moving a tool relatively to the workpiece in the same tool path as that of the cutting step in a region forming the corner are successively performed.
Claims8
A cutting method with a machine tool for cutting a workpiece based on a plurality of tool paths parallel to one another to machine the workpiece into a shape which includes a corner projecting outward, the method comprising:
- a step of repeatedly performing a machining step of machining the workpiece based on one tool path, and a moving step of moving to a start point of a step of machining based on another tool path parallel to the one tool path after completion of the machining step based on the one tool path;
- wherein
- the machining step includes a cutting step of cutting a workpiece on the one tool path, and a removal step of removing a burr produced on the corner by making a relative movement of a tool with respect to the workpiece on the same tool path and in the same direction as the tool path and the direction for the cutting step in an area forming the corner, and the cutting step based on the one tool path and the removal step are performed in succession.
A tool path generation device generating tool paths for machining a workpiece into a shape with a corner projecting outward, the tool paths including a plurality of tool paths parallel to one another for cutting the workpiece, the tool path generation device comprising:
- a path generation part which generates a machining tool path for machining the workpiece based on one tool path, and a moving tool path for moving to a start point of a machining tool path based on another tool path parallel to the one tool path after completion of machining based on the one tool path;
- wherein
- the machining tool path includes a cutting tool path including the one tool path for cutting the workpiece, and a removal tool path for removing a burr produced on the corner by making a relative movement of a tool with respect to the workpiece on the same tool path and in the same direction as the tool path and the direction for the cutting tool path in an area where the corner is formed, and
- the path generation part generates the cutting tool path based on the one tool path and successively generates the removal tool path based on the one tool path.
