一台加工目的已定的专用机床,它的控制方式可以有多种多样的选择。哪一种在机能上和经济上最为合适,这是一个很值得考虑的问题。数控(NC)曾经普遍被认为是比较理想的,然而目前仍然有不用数控的高度自动化的工业。计算机作为最高级的机床控制方法吗?对一些工件来说,又仍然存在计算机的数据传递速度太慢的问题。在某些情况下,采用凸轮控制却是最好的方案。怎样作出最后的选择呢?最好是从分析工作的要求和各项控制系统的性能出发。
A processing machine has been set for the purpose of its control methods can have a wide range of options. Which is the most appropriate in terms of function and economy is a question worth considering. Numerical control (NC) was once generally considered to be ideal, but there is still a highly automated industry that does not require NC. Is the computer the most advanced machine control method? For some artifacts, there is still the problem of too slow computer data transfer. In some cases, the use of cam control is the best solution. How to make the final choice? It is best to analyze the work requirements and the performance of the control system.
