AI Technical Summary

Technical Problem

Existing numerical controllers lack the ability to predictively recognize the moving state and direction of machine tool axes during a fault, making it difficult to determine which axis to move in which direction to a safe place after a disturbance, and fail to display necessary operation information for fault identification.

Method used

A numerical controller with a function that changes the display attribute of axis information on a screen based on the operating state of the axis during predictive recognition of a fault, displaying axes moving in positive and negative directions with different attributes and providing operation information like speed and block numbers.

Benefits of technology

Facilitates easy identification of axes to move to a safe place and displays operation information, reducing the time required for fault correction by clearly indicating the moving state and direction of axes and operation details.

Abstract

A numerical controller (1) configured to control the driving of at least one axis (50, 51, 52) installed in a machine based on an instruction of a program such that, when predictive detection of an occurrence of interference between a movable part moved by the driving of the axis and another object occurs, the numerical controller decelerates and stops the movement of the movable part, the numerical controller comprising: an attribute change processing part (330) configured to change a display attribute for displaying a coordinate value of the axis based on an operating state of the axis being driven when predictive detection of an occurrence of interference occurs;andan axis information display processing part (310) configured to display the coordinate value of the axis according to the display attribute changed by the attribute change processing part,wherein the display attribute indicates a movement direction of the machine without regard to the axis information.;

Claims

[1] A numerical controller (1) configured to control the driving of at least one axis (50, 51, 52) installed in a machine based on an instruction of a program such that, when a predictive detection of an interference occurrence between a movable part moved by the driving of the axis and another object occurs, the numerical controller decelerates and stops the movement of the movable part, the numerical controller comprising: an attribute change processing part (330) configured to change a display attribute for displaying a coordinate value of the axis based on an operating state of the axis being driven when a predictive detection of a failure occurrence is performed; and an axis information display processing part (310) configured to display the coordinate value of the axis according to the display attribute changed by the attribute change processing part, where the display attribute specifies a direction of movement of the machine without regard to the axis information. [2] The numerical controller according to claim 1, wherein the display attribute is defined by a display color of the information, a background color of the information, adding a letter indicating the operating state of the axis, adding a mark indicating the operating state of the axis, flashing the information, or inverse displaying the information. [3] Numerical control according to claim 1 or 2, further comprising: an operation information collection processing part (340) arranged to collect the operation information of the axis when a predictive detection of a fault occurrence occurs; and an operation information display processing part (350) configured to display the operation information collected by the operation information collection processing part. [4] A numerical controller according to claim 3, wherein the operation information is defined by information regarding a speed of the axis or a block number of the program for which a predictive detection of a failure occurrence is made.
