机床数控改造_Machine tool numerical control reforms
First, CNC systems and the development trend of history
一、数控系统发展简史及趋势
1946 birth of the world's first puter, which shows that human beings created to enhance and replace some of the mental work tools. It and human agriculture, industrial society in the creation of those who merely pared to manual tools, from a qualitative leap for mankind's entry into the information society laid the foundation. Six years later, in 1952, computer technology applied to the machine in the United States was born C machine tools. Since then, the traditional machine produced a qualitative change. Nearly half a century since C system has experienced two phases and six generations of development.
1946年诞生了世界上第一台电子计算机,这表明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,起了质的飞跃,为人类进入信息社会奠定了基础。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。
, Numerical Control (NC) phase (1952 to 1970)
、数控(NC)阶段(1952~1970年)
puter'putational speed low and the prevailing puting and data processing is not affected, but can not meet the requirements of real-time control machine. People have to use digital logic circuit "tied" into a single machine as a puter numerical control system, known as the hardware connection NC (HARD-WIRED NC), called the Numerical Control (NC). With the development ponents of this phase after three generations, that is, in 1952 the first generation - tube; 1959 of the second generation - transistor; 1965 of the third generation - small-scale integrated circuits.
早期计算机的运算速度低,对当时的科学计算和数据处理影响还不大,但不能适应机床实时控制的要求。人们不得不采用数字逻辑电路"搭"成一台机床专用计算机作为数控系统,被称为硬件连接数控(HARD-WIRED NC),简称为数控(NC)。随着元器件的发展,这个阶段历经了三代,即1952年的第一代--电子管;1959年的第二代--晶体管;1965年的第三代--小规模集成电路。

、C)阶段(1970年~现在)
To 1970, GM has been a puter and mass-produced. So it transplant system as the ponent of NC
