摘要
高端数控机床的不同几何加工误差对于不同工件加工面影响程度是变化的,其高精度来自于大量不同因素之间的完美协调配合,所以有必要研究造成加工误差的几何误差元素和构建空间加工误差数学模型。本文以某数控精密外圆磨床为研究对象,以分析复杂系统的多体系统理论和低序体理论为基础,进行数控磨床的几何误差元素分析,依据几何误差元素构建空间加工误差数学模型。该研究对高档数控磨床在加工精度研究中有重要的支撑意义,并为机床设计研究人员的误差补偿和精度优化设计工作提供理论依据。
The influence of different geometric machining errors on different machining surfaces of high-end CNC machine tools is variable,and its high accuracy comes from the perfect coordination of many different factors.Therefore,it is necessary to study the geometric error elements causing machining errors and build the mathematical model of spatial machining errors.A CNC precision cylindrical grinder is taken as the research object,based on the analysis of complex system theory of multi-body system and low order body theory.The geometric error elements of CNC grinding machine are analyzed,and the mathematical model of spatial processing error is constructed according to the geometric error elements.The research has important support significance for the machining accuracy of high-grade CNC grinder,and provides theoretical basis for the error compensation and precision optimization design for machine tool design researchers.
