摘要
阐述了基于结合面特性的机床整机精度设计系统结构以及4大关键模块,并利用VB开发工具实现了基于结合面特性的机床整机精度设计系统。利用该系统实现了机床结合面特性参数的分析与管理,并基于多体系统理论建立了三轴数控机床静态几何精度模型,可对机床在整个加工空间的几何误差进行预估并对误差源进行敏感性分析;同时集成ANSYS软件,基于结合面特性可对机床整机动态性能进行分析。另外,通过有效管理机床设计过程中的设计经验以及动静态精度分析的知识,将有效地支持机床设计。
The structure of machine tool accuracy design system based on joints characteristics and its four key modules were introduced. Machine tool accuracy design system based on joints characteristics was realized with Visual Basic as development tool. The analysis and management of characteristic parameters of joints were realized and the static geometry error model for three-axis CNC machine tool was set up by using the multi-body theory. With the system, it was accessible to estimate the geometrical errors over the whole processing space and to analyze the sensitivity errors and dynamic characteristics of machine tool based on the joints characteristic by integrating with Software ANSYS. By effectively managing all the knowledge including design experience, accuracy design and dynamic characteristics analyses knowledge during the process of machine tool design, the design can be supported effectively.
