前言 骨架仿形铣床的稳定性得到了保证以后,随之紧要的是确保仿形铣削精度,具备了这两个条件机床就能正常工作。 液压仿形铣床的操作者都有这样的体会:本来仿形铣削的工件是合格的,过了一段时间会出现超差现象,有时调在某一挡仿形速度铣削工件是合格的,换了另一挡速度铣削时就超差了,其原因何在?回答是肯定的:调整不当。 本文通过对仿形原理的分析,推导出仿形加工误差的表达式,论述了仿形精度同系统各元部件性能及其有关参数的相互关系,并结合
Foreword After the stability of the skeleton copying milling machine has been guaranteed, it is more important to ensure the accuracy of the copying milling. With these two conditions, the machine tool can work normally. Operators of hydraulic profiling milling machines all have the following experience: the original workpiece of the profiling milling is qualified, and after a period of time there will be an over-tolerance phenomenon. In some cases, it is qualified to transfer the workpiece in a certain profiling speed and change Another block speed when the ultra-poor milling, the reason? The answer is yes: the adjustment is not appropriate. In this paper, through the analysis of the profiling principle, the expression of the profiling error is deduced. The relationship between the profiling accuracy and the performance of each component of the system and its related parameters is discussed.
