重复性误差
A method for accuracy determination and repeatability of positioning of medium-accuracy numerically controlled machine tools based on step gauge was proposed. In the system, an auto-deviation measurement and auto backlash error compensation were developed.
提出一种低成本基于步距规的误差补偿系统,该系统可以实现普通精度级数控机床位置精度评定,并通过软件自动修改误差补偿表,使机床精度得以强化。
The main error sources of pulse width measurement, including counter's repeatability, trigger level timing error, time base error, the amplifier hysteresis error, LSD displayed error, etc. are analyzed.
