In the article the possibilities of a modern system with numerical control FMS-3000(3200) compared to other common control racks. Given the specific production examples of the design of control programs for cases odnostoronnego and multilayer milling in power engineering. The analysis of the total length of programs and the complexity of their adjustments in the processing elements of the same type having different geometric dimensions. It is concluded that the use of specialized modal cycles in the control FMS-3000(3200) significantly increases the efficiency of program-controlled machining.
