作者提出了一种新的—一相对零位校正法。这种方法是利用比较法测量工件相邻误差,然后加以修正的。尽管目前尚未付诸实践,但是,是一项很有希望和很有技术创新价值的方法。所阐述的原理,若能应用于螺纹磨床上修磨丝杠,可望达到一般校正加工方法所达不到的很高的精度——编者。 The authors propose a new - a relative zero correction method. This method is the use of comparative method to measure the workpiece adjacent to the error, and then be amended. Although not yet put into practice, but it is a promising and very innovative way of technological innovation. The principle described, if can be applied to the thread grinding grinder screw, is expected to reach the general correction machining method can not reach the high precision - Editor.
