Abstract
A machine tool, which performs machining on a workpiece using a tool, is equipped with a servo motor configured to cause axial movement of the tool or the workpiece, an imaging device configured to capture an image of the tool or the workpiece at a specified imaging magnification, a display unit configured to display the image captured by the imaging device, a speed compensating unit configured to compensate a command speed of the tool or the workpiece on the basis of the imaging magnification and thereby generate a compensated command speed, and a motor control unit configured to control the servo motor in a manner so that the tool or the workpiece is axially moved at the compensated command speed.
Claims13
A machine tool configured to perform machining on a workpiece using a tool, comprising:
- a motor configured to cause axial movement of the tool or the workpiece;
- an imaging device configured to capture an image of the tool or the workpiece at a specified imaging magnification;
- a display unit configured to display the image captured by the imaging device;
- a speed compensating unit configured to compensate a command speed of the tool or the workpiece based on the imaging magnification, and to thereby generate a compensated command speed;
- and
- a motor control unit configured to control the motor in a manner so that the tool or the workpiece is axially moved at the compensated command speed.
A speed control method for controlling a speed of axial movement of a machine tool configured to perform machining on a workpiece using a tool, wherein:
- the machine tool comprises a motor configured to cause axial movement of the tool or the workpiece;
- and
- the speed control method comprises:
- an imaging step of capturing an image of the tool or the workpiece at a specified imaging magnification;
- a displaying step of displaying the captured image;
- a speed compensating step of compensating a command speed of the tool or the workpiece based on the imaging magnification, and thereby generating a compensated command speed;
- and
- a motor controlling step of controlling the motor in a manner so that the tool or the workpiece is axially moved at the compensated command speed.
