前言随着国民经济和国防事业的发展,人们对机械传动付质量的要求愈来愈高,金属切削机床传动链精度问题亦就成了机床设计与研究的重要课题之一。不少人对这个问题进行了研究[5][6][7][8][9][10][11],然而,问题并没有根本解决。重要原因之一在于从各种传动误差测量仪的记录仪上只能看到机床传动链的周节累 Preface With the development of the national economy and national defense, the quality of the mechanical transmission is getting higher and higher. The precision of the transmission chain of the metal cutting machine has also become one of the important topics in machine tool design and research. Many people have studied this issue [5] [6] [7] [8] [9] [10] [11]. However, the problem has not been solved at all. One of the important reasons is that from the various transmission error measuring instrument recorder can only see the machine tool chain weeks tired
