数控机床的改造(中文5300字,英文4300字)
一、数控系统发展简史及趋势
     1946年产生了世界上第一台电子计算机,这表明了人类创造了可增强和部分代替脑力劳动的工具。它与人类在农业、工业社会中创造的那些只是增强体力劳动的工具相比起来,起了质的飞跃,为人类进入信息社会奠定了基础。
在6年后,即在1952年,计算机技术应用到了机床上,在美国诞生了第一台数控机床。从此,传统机床产生了质的变化。近半个世纪以来,数控系统经历了两个阶段和六代的发展。

First  numerical control system development summary brief history and tendency
In 1946 the first electronic accounting machine was born in the world, this indicated the humanity created has been possible to strengthen and partially to replace the mental labor the tool. It with the humanity these which in the agriculture, the industry society created only is strengthens the physical labor the tool to compare, got up the quantitive leap, entered the information society for the humanity to lay the foundation.
After 6 years, in 1952, computer technology applied to the engine bed , the first numerical control engine bed were born in US. From this time on, the traditional engine bed has had the archery target change. Since nearly half century, the numerical control system has experienced two stages and six generation of development.
1.1 Numerical control (NC) stage (1952 ~ 1970)
