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, each spaced apart by a pick feed, to machine the workpiece into a shape which includes a corner projecting outward, the method comprising:
- a machining step of machining, using a tool, the workpiece based on one tool path, the machining step comprising,
- a cutting step of cutting the workpiece using the tool along the one tool path, and
- a removal step of removing a burr by making a relative movement of the tool with respect to the workpiece on the same tool path and in the same direction as the direction for the cutting step at least in an area forming the corner, the burr being produced in the cutting step by making the relative movement of the tool with respect to the workpiece along a shape of the corner projecting outward, and the cutting step based on the one tool path and the removal step being performed in succession;
- a moving step of moving the tool to a start point of another tool path parallel to the one tool path and spaced apart by the pick feed from the one tool path after completion of the machining step based on the one tool path;
- and
- a repeating step of repeating the machining step and the moving step.
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, each spaced apart by a pick feed, for cutting the workpiece, the tool path generation device comprising a non-transitory storage media storing thereon a program that, when executed by a computer, performs the steps of:
- generating a machining tool path for machining, using a tool, the workpiece based on one tool path, the generating comprising,
- generating a cutting tool path including the one tool path for cutting the workpiece using the tool, and
- generating a removal tool path for removing a burr by making a relative movement of the tool with respect to the workpiece on the same tool path and in the same direction as the direction for the cutting tool path at least in an area where the corner is formed, the burr being produced by making the relative movement of the tool with respect to the workpiece along a shape of the corner projecting outward based on the cutting tool path,
- moving the tool to a start point of another machining tool path parallel to the one tool path and spaced apart by the pick feed from the one tool path after completion of machining based on the one tool path;
- and
- repeating the generating of the machining tool path and the moving of the tool.
