引言
数控技术也叫计算机数控技术,目前它是采用计算机实现数字程序控制的技术。这种技术用计算机按事先存贮的控制程序来执行对设备的控制功能。由于采用计算机替代原先用硬件逻辑电路组成的数控装置,使输入数据的存贮、处理、运算、逻辑判断等各种控制机能的实现,均可以通过计算机软件来完成。
中核苏阀科技实业股份有限公司主要就是生产阀门的,生产阀门所用的机床也是很多的,有车床、镗床、钻床、数控车床、加工中心等。在生产阀体时,运用数控车床加工占的比例还是很大的,而本文主要阐述了在数控加工过程中解决的工艺问题及编程问题,能够结合本专业的知识,使自己的知识水平和技能水平得到提高。
(一)企业简介
公司于一九九七年创立,是在承袭了中国核工业集团公司苏州阀门厂的主营业务、品牌、质保、技术和管理诸优势的基础上创立的上市股份公司,目前注册资本20160万元,是中国阀行业和核工业系统的首家上市公司。
