Abstract
A tool path generation device for machining a workpiece with a machine tool including a reading and interpreting portion which reads out a tool path from a machining program, a target coordinate value calculating portion which sets a plurality of target points at equal intervals on the read out tool path, and a curve approximation calculating portion which generates a tool path based on the plurality of target points, so as to obtain a smooth machined surface without formation of step differences between adjacent tool paths.
Claims6
A tool path generation method for machining a workpiece with a machine tool comprising:
- reading out a tool path for machining a workpiece from a machining program;
- setting a plurality of target points at equal intervals on the read out tool path;
- calculating an approximation curve based on the plurality of target points;
- and
- generating a tool path along the approximation curve.
A tool path generation method for machining a workpiece with a machine tool comprising:
- reading out a tool path for machining a workpiece from a machining program;
- setting a plurality of target points at equal intervals on the read out tool path;
- calculating average coordinates of adjacent target points, and generating a tool path by connecting the average coordinates.
