多轴微细铣削机床的精度设计方法研究
Accuracy design method of multi-axis micro milling machines
摘要
Abstract
High precision machine tools are the fundamentals of micro machining. At present, in the design process of high precision machine tools, the accuracy of each axis is selected mainly based on designers' experience or intuitively from the accuracy requirements. It cannot satisfy the design requirements for multi-axis micro milling machine tools. Based on the accuracy design method comprising of accuracy analysis and accuracy allocation, kinematics errors including single-axis positioning accuracy was modelled aiming at a novel tabletop simultaneous 5-axis micro milling machine tool. The tendency and distribution of the effect of single-axis motion accuracy on the final motion accuracy were solved to accomplish the accuracy analysis. According to the final motion accuracy requirements and key design parameters, accuracy requests for linear axes and rotary axes were reasonably set. Accuracy was solved for B axis and C axis respectively in the workspace. Optimization and allocation of single-axis accuracy were realized. Components of each axis can be selected scientifically according to the research results in the design process. The introduced method also adapts to medium and large-sized simultaneously multi-axis machine tools.关键词
