20世纪人类社会最伟大的科技成果是计算机的发明与应用,计算机及控制技术在机械制造设备中的应用是世纪内制造业发展的最重大的技术进步。自从1952年美国第1台数控铣床问世至今已经历了50个年头。数控设备包括:车、铣、加工中心、镗、磨、冲压、电加工以及各类专机,形成庞大的数控制造设备家族,每年全世界的产量有10~20万台,产值上百亿美元。世界制造业在20世纪末的十
The greatest scientific and technological achievements of human society in the 20th century were the invention and application of computers. The application of computer and control technology in machinery manufacturing equipment was the most significant technological progress in the development of manufacturing industry in the 21st century. It has been 50 years since the United States first CNC milling machine was introduced in 1952. CNC equipment include: car, milling, machining centers, boring, grinding, stamping, electrical processing and various types of special plane, forming a huge family of CNC manufacturing equipment, the world’s annual output of 10 to 200,000 units, the output value of billions of dollars. World manufacturing industry at the end of the 20th century
