2、中、小批量零件加工我们选择机床经济型 数控改造。总体设计方案：在普通车床上采用适合现场实时控制的 80C51 单片机为控制器， 以运行特性好、可靠性高的步进电机为驱动执行元件进行数控改造。 关键词关键词：数控、车床、改造、80C51 单片机；步进电机； Abstract:Numerical Control (NC) is any machining process in which the operations are executed automaticallu in sequences as specified by the program that contains the inform

3、ation for the tool movement .When Numerical Control is performed under computer supervision, it is called Computer Numerical Control (CNC).CNC machines have many advantages over conventional machines. For example, there is a possibility lf performing operations on the same machine in one setup and p

4、roduction is significantly increased. One of its disadvantages is that they are quite expensive. In our country conventional machine is used widely. So if the machines are replaced, there is going to need a large money. In order to agree with the development of our economy, we can reform the conventional machines. The overall master design: The way to NC improvement of general machine tool was introduced that using single-chip computer 80C51 to realize the real-time control and driving by ste
