在设计机床电气控制线路时,如果仅凭直觉经验,凭记住几个典型环节的控制线路,对于控制动作简单的机床是比较容易对付的。但是,当遇到控制动作复杂的机床,这种直觉经验设计法会给电气控制线路的设计工作带来很大的困难,尤其是对于设计工作的初学者,更容易造成各个环节顾此失彼的局面。为了克服这种盲目的设计方法,我们经反复摸索,发觉如运用逻辑代数方法于机床继电控制线路的设计工作,能实现多、快、好、省的目的。我们设计双面六工位转塔式组合机床的电气控制线路时,原来按直觉经验设计,不仅费力,而且要用八十多只继电器才能完成控制动作的要求。后来运用了逻辑代数设计方法,线路结构得到很大的简化,仅用三十多只继电器就能满足控制动作的要求,而且线路的逻辑性
In the design of machine electrical control circuit, if only intuitive experience, relying on several typical links of the control circuit, the control of simple machine tool is relatively easy to deal with. However, in the case of machine tools with complicated control actions, this intuitionistic experience design method will bring great difficulties to the design of electrical control circuits. Especially for beginners who design, it is more likely to result in the loss of all aspects. In order to overcome this blind design method, after repeated exploration, we found that if we use the logic algebra method to design the relay control circuit of the machine tool, we can realize the purpose of more, faster, better and more economical. When we designed the electrical control circuit of the double-sided six-station turret combined machine tool, it was not only laborious but also more than 80 relays to complete the control action when originally designed according to intuition. Later, the use of logical algebra design method, the circuit structure is greatly simplified, only with more than thirty relays to meet the requirements of the control action, and the logic of the circuit
