摘要

摘要: 对用六轴四联动数控系统代替六轴联动数控系统的可行性进行研究。首先运用D-H法对各轴运动变量进行求解并探讨C轴运动变量求解方法。分别对机床各轴作为随动轴引起的误差进行计算,分析和评估。确定了随动轴和联动轴配合运动方案。对六轴四联动数控砂带抛磨机床产生的加工误差进行了处理。最后运用间接法比较加工效率在误差处理前后的变化程度。结论证实在加工效率允许范围内用六轴四联动数控系统代替六轴联动数控系统抛磨曲面是可行的。

Abstract: We use the D-H role to solve each axis motion variable and then discuss how to solve the C-axis motion variable. After this we calculate, analyze and evaluate the machining errors of each axis of the CNC grinding system, which are caused by follow-axis motions. The major work we have done is that we determine a follow-axis and joint-axis cooperated motion scheme. Then we process the machining errors of the six-axis and four-link CNC abra-sive belt grinding system. Finally we use the indirect method to compare the degrees of changes in the efficiency before and after the error-processing. The study results show that the use of the six-axis an processing d four-link CNC abrasive belt grinding system rather than the six-axis CNC abrasive belt grinding system for grinding a curved surface is feasible within the range in which its processing efficiency is allowed.
