Automatic Compensation Method of Numerical Control Equipment Probe Measured Value

Abstract

The invention discloses an automatic compensation method of a probe measuring value of numerical control equipment. The automatic compensation method of a probe measuring value of numerical control equipment includes the steps: by means of a planned path, utilizing a probe to measure the positional deviation of key points of a workpiece, and storing the deviation vector value of each key point to a specified position; adding a plurality of M57, M58 and M59 commands at the preset position on the planned path; analyzing and executing the planned path; entering a automatic deviation counting and compensation mode when the M57 command appears; when the M59 command appears, transmitting the corresponding deviation vector value and executing automatic compensation; and when the M58 command appears and the M57 command does not appear, directly executing the analyzed motion command without performing compensation. Being highly integrated with a core algorithm of a numerical control system and automatically applying the discrepancy measured by the probe to a cutter track of the program, the automatic compensation method of a probe measuring value of numerical control equipment enables the most tedious compensation process to be realized through automation, and has the advantages of being high in accuracy, being high in efficiency, being high in applicability, reducing the amount of labour of technologists in the site, and reducing the demand threshold.

Description

technical field [0001] The invention relates to a numerical control equipment solution. Background technique [0002] In today's increasingly pursuit of exquisite appearance, the proportion of "highlight" in the mobile phone casing is gradually expanding. Due to technological requirements, the "high-gloss" process is often a part of multiple processes. Due to the influence of multiple clamping and processing in the previous process, its overall or partial dimensions may have a certain slight change. If it is not corrected, high-tech After processing, it is easy to be sensitively observed, such as the problem of large and small edges. [0003] For this reason, it is necessary to add detection equipment such as probes to achieve one inspection for each workpiece, and automatically detect the position deviation of key points before processing, and then make appropriate corrections to the NC tool path program for these deviations to obtain a compensated tool. road track.

AI Technical Summary

Problems solved by technology

[0010] 1. The manual workload is heavy, because the NC tool path files are generally small line segments or small arcs, which need to be revised one by one;

[0011] 2. The accuracy is poor. For the arc, it must be broken into some small line segments and then corrected, losing the original accuracy;

[0012] 3. The tool path file expands greatly. For example, a circular arc must first be broken up into many tiny line segments to ensure the specified accuracy;

[0013] 4. The efficiency is low, because the macro program is generally written in an interpretive language, and the execution efficiency is relatively low;

[0014] 5. Poor versatility, different tool path programs need to be corrected by different manual coding;

[0015] 6. Debugging is difficult, and the first finished product cycle is long
