1.研究目的在机械加工中,总是不断的碰到新的加工任务,车削产生长切屑的材料时,为了能断屑或控制切屑,有时需采取投资费用较大的技术措施。在自动机床和数控机床上加工时,为了保障操作人员的安全,防止工件和刀具受损以及避免由于切屑阻塞而使切削中断,需要采取一种简单而有效的方法控制切屑。因此,作为一种新的加工方法,它应该具 1. Research purposes In machining, always meet new processing tasks, turning the production of long chips, in order to chip or control chip, and sometimes need to take greater investment costs of technical measures. When machining on automatic machines and numerically controlled machine tools, it is necessary to take a simple and effective method of controlling the chips in order to protect the safety of the operator, to prevent damage to the work piece and the tool, and to avoid cutting interruption due to chip blocking. Therefore, as a new processing method, it should have
