在现代化机械制造业中,虽然少无切削工艺发展很快,但机械加工的劳动量,仍在机械制造业中占有很大的比例。因此,如何提高生产率,保证零件加工精度、降低成本费用,就成为一个十分重要的问题。为了解决这一问题,国内外许多学者、工程技术人员通过研究切削加工的发展史证明,刀具材料和刀具结构的改变,是解决这一问题的关键之一。可转位车刀的出现,是代表刀具材料和刀具结构改进的产物。在
In the modern machinery manufacturing industry, though less and less non-cutting technology has developed rapidly, the amount of labor for machining still occupies a large proportion of the machinery manufacturing industry. Therefore, how to improve productivity, ensure the accuracy of parts processing, and reduce costs and expenses has become a very important issue. In order to solve this problem, many scholars at home and abroad, engineers and technicians through the study of the history of the development of cutting process proved that changes in tool material and tool structure is one of the keys to solve this problem. The emergence of turning turning tools, is representative of the tool material and tool structure to improve the product. in
