Abstract
A motion mechanism moves a workpiece relative to a cutting tool with a convex cutting edge. A controller controls the relative movement between the workpiece and the cutting tool by the motion mechanism and an orientation of the cutting tool. The controller intermittently or continuously changes the orientation of the cutting tool to cause a part of the cutting edge that has not been used for cutting to form a finished surface.
Claims6
A machining apparatus comprising:
- a motion mechanism structured to move a workpiece relative to a cutting tool with convex cutting edge;
- and
- a controller structured to control the relative movement between the workpiece and the cutting tool by the motion mechanism and an orientation of the cutting tool, wherein
- the controller changes the orientation of the cutting tool by a change amount based on a feed amount to cause a part of the cutting edge that has not been used for cutting to form a finished surface.
A cutting method comprising:
- moving a workpiece relative to a cutting tool with a convex cutting edge;
- and
- controlling an orientation of the cutting tool, wherein
- in the controlling an orientation, the orientation of the cutting tool is changed by a change amount based on a feed amount to cause a part of the cutting edge that has not been used for cutting to form a finished surface.
A recording medium storing a program executable by a computer, the program causing the computer to execute:
- moving a workpiece relative to a cutting tool with a convex cutting edge;
- and
- controlling an orientation of the cutting tool, wherein
- the controlling an orientation includes changing the orientation of the cutting tool by a change amount based on a feed amount to cause a part of the cutting edge that has not been used for cutting to form a finished surface.
