Abstract: In the electrical debugging of Siemens CNC system, the parameters of each machine tool need to be input manually by the debugger one by one. After rough statistics, the parameters of five-axis machine tools need to be set up to nearly 300, while the parameters of 10-axis machine tools need to be set up to more than 500. The process is tedious and error-prone. This paper briefly introduces how to implement the batch of parameters of CNC system by executing SPF files in Siemens subsystem. Volume settings.
