本文在分析了现有CNC齿轮测量仪驱动系统的工作原理及其优缺点的基础上,提出了一种用测头控制进行跟踪驱动的方法.它可用于齿形测量及齿向测量,既适合台式测量仪的驱动系统,更适合于便携式就地测量系统。与现有的CNC展成驱动法相比,具有系统简单,控制速度快,应用范围广,工作稳定等优点,是一种很有前途的驱动控制方法. Based on the analysis of the working principle and the advantages and disadvantages of the existing CNC gear measuring instrument drive system, this paper presents a method of tracking drive with the probe control, which can be used for tooth profile measurement and tooth orientation measurement, The drive system of the desktop gauge is more suitable for portable in-situ measurement systems. Compared with the existing CNC display drive method, it has the advantages of simple system, fast control speed, wide application range and stable operation, and is a promising driving control method.
