Abstract
A quality determination device includes an acquisition unit for acquiring a drive current during tapping, from a motor provided in a machine tool that performs tapping, and a determination unit for determining acceptance or rejection of a screw hole formed by the tapping, based on the drive current, an electric power of the motor obtained from the drive current, or a torque of the motor obtained from the drive current.
Claims10
A quality determination device, comprising:
- one or more processors that execute computer-executable instructions stored in a memory, wherein the one or more processors execute the computer-executable instructions to cause the quality determination device to:
- acquire a drive current during tapping, from a motor provided in a machine tool that forms a screw hole in a workpiece by the tapping;
- and
- determine acceptance or rejection of the screw hole formed by the tapping, based on the drive current, an electric power of the motor obtained from the drive current, or a torque of the motor obtained from the drive current during the formation of the screw hole.
1 more element
A quality determination method performed by executing, by one or more processors, computer-executable instructions stored in a memory, the method comprising:
- an acquisition step of acquiring, by the one or more processors, a drive current during tapping, from a motor of a machine tool that forms a screw hole in a workpiece by the tapping;
- and
- a determination step of determining, by the one or more processors, acceptance or rejection of the screw hole formed by the tapping, based on the drive current, an electric power of the motor obtained from the drive current, or a torque of the motor obtained from the drive current during the formation of the screw hole.
