摘要

摘要: 研究了适合多种结构布局形式的统一坐标变换方法,开发出数控系统5坐标变换函数库,并作为坐标变换控制模块集成到数控系统中.分析了5坐标数控机床运动学模型,归纳出12种5坐标数控机床结构布局,并推导了对应的坐标变换数学算法.通过结构分析和数学变换将12种算法扩展归纳到3类基础算法,并基于3类基础算法开发出适合多种机床结构布局的5坐标变换库.利用机床三维仿真系统验证了5坐标变换库的可行性,并将该坐标变换库集成到北京航空航天大学开发的CH-2010开放式数控系统中.

Abstract: The uniform method of coordinate transformation was studied, which is suited for a variety of structures of 5-axis machine tool. CNC(computer numerical control) coordinate transformation library was developed, which could be integrated into CNC system as a coordinate transformation control module. The kinematics of 5-axis machine tool was analyzed, 12 types of 5-axis machine tool structure were listed, and the corresponding coordinate transformation algorithms were derived. 3 types of basic algorithms were obtained through mathematical transformation, and a 5-coordinate transformation library was developed based on the basic algorithms. The feasibility of 5-coordinate transformation library was verified by a 3D simulation system, and the library was integrated into CH-2010 open CNC system developed by Beijing University of Aeronautics and Astronautics.
