Expression system of machining information of numerical control machine tool

Abstract

The invention discloses an expression system of the machining information of a numerical control machine tool. The expression system comprises a sensing unit and a field bus and is characterized by further comprising a storage module, a calculating module, a selecting module, a coloring module, a control module, an overlapping module and an output module, wherein a value domain R of an error increment value deltaE is determined according to experience data, the domain R of the error increment value deltaE is marked through a color tape composed of a variety of colors, and different error increment values deltaE correspond to different colors S; the control module is used for determining three-dimensional coordinate positions (X, Y and Z) information and outputting the information to the overlapping module; the overlapping module is used for overlapping a color S corresponding to the error increment value deltaE on the three-dimensional coordinate positions (X, Y and Z) depicted by a time t movement track; and the output module is used for outputting a colored error coordinate (X, Y, Z and S) composed of the overlapping module to a numerically-controlled system man-machine interface. According to the expression system, the value results of various physical quantities are depicted through information such as graphs and colors, and the state change and machining effects that a workpiece is machined by the numerical control machine tool are reflected to an operator visually and vividly.

Description

technical field

[0001] The invention relates to an expression system of numerical control machine tool processing information. Background technique

[0002] During the machining process of CNC machine tools, physical quantities such as length, speed, angular velocity, current, voltage, power, heat, and frequency are changing all the time, and reflect the state changes in the process of machining workpieces by CNC machine tools from different aspects. Usually, when the numerical control system controls the machine tool components to complete the machining process, the parameters of various state changes are fed back to the numerical control system in the form of numerical values, and the operator is notified through the human-machine interface (HMI) of the numerical control system. The operator cannot visually and intuitively Viewing the trend or gradual process of state changes in the processing process is not conducive to the operator's analysis and judgment of state change...
