Abstract
An apparatus for detecting the status of a tool in a machine tool may include: a sensor unit configured to sense acceleration of a spindle of the machine tool in an x-axis direction and a y-axis direction during processing; and a processing device configured to convert the x-axis signal and the y-axis signal, sensed by the sensor unit, into signals capable of representing a cutting force by processing the x-axis and y-axis signals, detect a resultant force, and plot the detected resultant force on a polar coordinate system.
Claims10
An apparatus for detecting the status of a tool in a machine tool, comprising:
- a sensor unit configured to sense acceleration of a spindle of the machine tool in an x-axis direction and a y-axis direction during processing, wherein the sensor unit comprises:
- a first acceleration sensor configured to sense the acceleration of the spindle in the x-axis direction;
- a first amplifier configured to amplify an x-axis signal sensed by the first acceleration sensor;
- a second acceleration sensor configured to sense the acceleration of the spindle in the y-axis direction;
- and
- a second amplifier configured to amplify a y-axis signal sensed by the second acceleration sensor,
- wherein the first and second acceleration sensors are each disposed at a preset angle;
- and
- a processing device configured to convert the x-axis signal and the y-axis signal, sensed by the sensor unit, into signals capable of representing a cutting force by processing the x-axis and y-axis signals, detect a resultant force, and plot the detected resultant force on a polar coordinate system.
