基于FANUC系统的模拟主轴速度误差控制方法

Spindle Speed Error Control Method Based on FANUC System

针对主轴实际速度与主轴指令速度S之间存在较大误差的问题,以FANUC Oi Mate-TC数控系统实验培训平台为例,当主轴转速在800 r/min时,误差控制在3%以内。根据模拟主轴速度误差调整方法,调整速度误差。实践验证:采用模拟主轴速度误差调整方法,有效解决了主轴实际速度与主轴指令速度S误差较大的问题。这对模拟主轴广泛应用于中、低档数控机床,主轴速度精度控制有较高的工程应用价值。

Aiming at the problems with large errors between the actualspindle speed and the spindle command speed S,take FANUC Oi Mate-TC CNC system experimental training platform as an example,when the spindle speed is 800r/min,the error is controlled within 3%.According to the method of adjusting the speed error of the simulated spindle,the speed error is adjusted.Practice shows that the method of adjusting the speed error of the simulated spindle effectively solves the problem that the actual speed of the spindle and the command speed of the spindle have large error S.It is widely used in moderate and low-grade NC machine tools for simulating spindle,and has high engineering application value for spindle speed precision control.
