Command sequence-based method for displaying processing state information of digital control machine tool

Abstract

The invention discloses a command sequence-based method for displaying processing state information of a digital control machine tool, comprising the following steps of: firstly, acquiring various kinds of process state information of each interpolation period of a digital control system, with an executing program segment number as a group index, recording all acquired processing state information obtained in the process of executing a program segment to a processing state information storage area; and acquiring command sequence information and the processing state information necessary for displaying from the processing state information storage area, and displaying a processing state information curve chart based on a command sequence on a human-computer interface, wherein the processing state information curve chart is provided with two displaying modes of time uniformity and command uniformity and can be used for displaying any program segment dynamically. The method can ensure that information data are thoroughly acquired and have high real time, is beneficial to the analysis and diagnosis of processing conditions by a user and ensures that the user simultaneously observes the command sequence and the processing state information more simply, clearly and conveniently.

Description

technical field [0001] The invention relates to the technical field of numerical control, in particular to a method for displaying processing status information of a numerical control machine tool based on instruction sequences. Background technique [0002] CNC machine tool is an efficient automatic processing equipment. It strictly follows the processing program and automatically processes the workpiece. The program directly input from the CNC system for processing is called the CNC processing program. The CNC processing program represents All the actions to be completed by the CNC machine tool. A complete NC machining program consists of three parts: program name, program content and program end command. The program content is the core of the entire NC machining program. It consists of several program segments, and each program segment is a complete processing step unit. , which consists of several instruction words. The instruction word refers to a series of characters...

In this type of monitoring and diagnosis system, the information can be displayed in the form of a correlation graph, but these graphs are established based on the time domain or frequency domain, and the horizontal axis is either the running time or the frequency of information occurrence. If you want to find the execution state of the NC machining program in a certain processing state, that is, the relationship between the processing state and the command sequence, you cannot obtain

For example: NC machine tools process a NC machining program composed of countless small line segments. Usually, the NC machining program composed of small line segments is used to process complex curved surface parts. Computer-aided programming systems usually use several small line segments to fit the surface of the part. Contour, the generated small line segment is often about 1 mm, so it is difficult for the user to observe the program segment corresponding to each small line segment that constitutes the contour curve of the part through the eyes during processing. When the surface of the processed part does not meet the When there are small defects required, the program segment that causes the error cannot be located because of the small surface defect, and it is not convenient to make corresponding processing

[0005] The above method of obtaining and displaying the machining status information of CNC machine tools cannot establish the direct relationship between the CNC machining program and various machining states in the machining process, which brings difficulties to the analysis and diagnosis of the machining status for users.
