Abstract
An NC machining system includes a chuck that clamps a workpiece; a first rotation axis, located opposite the chuck, that rotates as a main axis; a second rotation axis that rotates about its center on the first axis; a numerical control apparatus that outputs, according to on pre-programmed machining instructions, rotation commands for the first and the second rotation axes; and a tool, fixed on the second rotation axis, that moves along a circumference of the workpiece by a rotation of the first rotation axis, and whose machining radius is determined by a rotation of the second rotation axis.
Claims8
A numerical control machining system, comprising:
- a chuck that clamps a workpiece;
- a first rotation axis, located opposite the chuck, that rotates as a main axis;
- a second rotation axis that rotates about its center on the first rotation axis;
- a numerical control apparatus that outputs, according to pre-programmed machining instructions, rotation commands for the first and the second rotation axes;
- and
- a tool, fixed on the second rotation axis, that moves along a circumferential surface of the workpiece by a rotation of the first rotation axis, and whose machining radius is determined by a rotation of the second rotation axis.
A numerical control apparatus, the apparatus configured to output:
- a rotation command that instructs a first rotation axis to moves along a circumferential surface of a workpiece;
- and
- a rotation command that instructs a second rotation axis to determine a machining radius of a tool, according to pre-programmed machining instructions for the first rotation axis, located opposite a chuck for clamping the workpiece, that rotates as a main axis, and for the second rotation axis on which the tool is fixed and that rotates about its center on the first rotation axis.
