一、引言　　机械制造工艺学是一门重要的老专业课程,并且一直沿用原苏联的教学体系,其实验也为成熟的传统实验。近几年来,随着计算机技术的迅猛发展,机械制造领域的软硬件不断地涌现和更新,特别在计算机辅助和机床数控方面进步更快。尽管新版的一些教材反映了这个变化,但在实 I. INTRODUCTION Machinery manufacturing technology is an important old professional course, and has been using the teaching system of the former Soviet Union, the experiment is also a mature traditional experiment. In recent years, with the rapid development of computer technology, hardware and software in the field of mechanical manufacturing are constantly emerging and updated, especially in computer aided and machine tool numerical control progress faster. Although some of the new textbooks reflect this change, it is in fact
