【摘要】：随着现代化科学、技术和生产的发展,许多高精度、低粗糙度、特硬和有色金属材料制成的小尺寸轴、盘类回转体零件,要求以车代磨一次加工成功,这就对数控车床的速度、精度和刚度提出了很高的要求,伺服特性是衡量数控车床加工质量高低的最重要的性能指标之一。因此,数控车床进给系统的研究已成为一个十分重要的课题。本文对FANUC系统数控车床的进给伺服系统进行了研究分析,根据伺服进给系统的结构关系和各组成部分之间的内在联系,通过理论推导的方法分别建立了数控车床伺服进给系统的机械传动部分模型,电气伺服驱动部分模型,并对伺服驱动部分中的电流环、速度环、位置环进行分别建模。最后推导总结各分体模型,建立了包含机械传动部分及电气伺服驱动部分在内的综合进给系统模型。结合实际机型,选取相关参数,对各模型进行仿真,并对仿真结果进行分析总结。在对数控车床进给伺服系统进行分析、建模、仿真后,本文着重介绍了如何利用FANUC数控系统Servo Guide软件进行伺服系统中伺服参数的调整,对Servo Guide软件测试出来的图形进行分析,验证了仿真结果的同时也总结了基于FANUC数控系统的数控车床进给伺服系统的电气调试及优化方法。其方法及结果可为工程设计及调试提供实际参考依据,具有一定的工程应用价值。
[Abstract]:With the development of modern science, technology and production, many parts with high precision, low roughness, special hard and nonferrous metal materials made of small size shafts and diskettes are required to be machined successfully by turning instead of grinding once, which is to the speed of numerical control lathe. High precision and rigidity are required. Servo characteristic is one of the most important performance indexes to measure the machining quality of NC lathe. Therefore, the research of CNC lathe feed system has become a very important subject. In this paper, the feed servo system of CNC lathe in FANUC system is studied and analyzed. According to the structure relation of servo feed system and the internal relation between each component, The mechanical drive model and electric servo drive part model of servo feed system of NC lathe are established by the method of theoretical derivation, and the current loop, velocity loop and position loop in servo drive part are modeled respectively. Finally, the model of the integrated feed system including the mechanical drive part and the electric servo drive part is established. Combined with the actual model, the relevant parameters are selected to simulate each model, and the simulation results are analyzed and summarized. After analyzing, modeling and simulating the feed servo system of NC lathe, this paper emphatically introduces how to adjust the servo parameters of servo system by using Servo Guide software of FANUC NC system, and analyze the graph tested by Servo Guide software. The simulation results are verified and the electrical debugging and optimization methods of feed servo system of NC lathe based on FANUC are also summarized. The method and results can provide practical reference for engineering design and commissioning, and have certain engineering application value.
