Abstract

A diagnostic result display method in a diagnostic device calculates a diagnostic result by a determination of a predetermined state and a certainty factor of the determination. The diagnostic result display method includes setting preset predetermined colors to predetermined states, setting a preset area of a geometric shape according to certainty factors, and displaying the area of the geometric shape in at least one of the predetermined colors.

Claims

1. A diagnostic result display method in a diagnostic device disposed in a machine tool that calculates a diagnostic result by a determination of a predetermined state, and a certainty factor of the diagnostic result, the diagnostic result display method comprising:

analyzing information obtained from at least a sensor disposed in the machine tool and a numerical control device with an analyzer;

sensing a vibration of a main spindle of the machine tool with a vibration sensor disposed in the machine tool;

analyzing the sensed vibration of the main spindle of the machine tool with an analyzer disposed in the machine tool;

analyzing torque information of at least one of x, y, and z feed axes with the analyzer;

utilizing the torque information to control a servo motor obtained from the numerical control device;

calculating with a determining unit, the determining unit including at least a neural network, one of a normal state or an abnormal state of at least one of the main spindle or at least one of the x, y, and z feed axes, and a certainty factor thereof;

setting predetermined colors to predetermined states;

setting a preset area of a geometric shape according to certainty factors; and

displaying the area of the geometric shape in at least one of the predetermined colors.

2. A diagnostic result display method in a diagnostic device disposed in a machine tool that calculates a diagnostic result by a determination of a predetermined state, a certainty factor of the diagnostic result, and a degree of the state, the diagnostic result display method comprising:

analyzing information obtained from at least a sensor disposed in the machine tool and a numerical control device with an analyzer disposed in the machine tool;

sensing a vibration of a main spindle of the machine tool with a vibration sensor disposed in the machine tool;

analyzing the sensed vibration of the main spindle of the machine tool with the analyzer disposed in the machine tool;

analyzing torque information of at least one of x, y, and z feed axes with the analyzer;

utilizing the torque information to control a servo motor obtained from the numerical control device;

calculating with a determining unit, the determining unit including at least a neural network, one of a normal state or an abnormal state of at least one of the main spindle or at least one of the x, y, and z feed axes, and a certainty factor thereof;

setting predetermined colors to predetermined states;

setting a preset area of a geometric shape according to at least one of degrees of states or at least one of the certainty factors; and

displaying the area of the geometric shape in at least one of the predetermined colors.
