以西门子840D sl SINUMERIK Operate为系统应用框架,基于Trace Service数据采集功能,开发了一种以空走S试件轨迹为对象的数控机床五轴联动精度评估模块。针对Trace Service数据采集机制进行核心原理分析,通过S试件轨迹运行过程的数据需求,梳理数据采集流程并设计坐标轴数据采集子模块,再将数据采集结果进行分析提取进行坐标轴向刀尖点的转换,结合图形数字化手段完成轮廓误差图形与指标展示,综合实现数控机床五轴联动精度的评估。该模块利用S试件优秀的联动精度评估性能,集成高效数据采集与轮廓评估展示,避免了传统模式下采集和评估过程的繁琐性,有效提升了评估过程的经济性与效率。

This paper targets the Siemens 840D sl SINUMERIK Operate as the system application framework,and based on the Trace Service data acquisition function,a five-axis linkage accuracy evaluation module for CNC machine tools is developed,which targets the trajectory of S part as the object.Based on data requirements of the trajectory of the S part during operation,this paper analyzes the core principle of the Trace Service data acquisition mechanism,sorts the data acquisition process and designs the sub-module of the coordinate axis data acquisition through the data requirements of the trajectory of the S part during operation,analyzes and extracts the results of the data acquisition to convert the axis coordinates to tool tip points,and completes the display of graph and index of the contour error with the graphical-digital method,so as to achieve the evaluation of the five-axis linkage accuracy of the CNC machine tool.This module uses the excellent linkage accuracy evaluation performance of S part,integrates efficient data acquisition and contour evaluation display,avoids the fussy process of traditional acquisition and evaluation,and effectively improves the economy and efficiency of the evaluation.
