For example, once variable speed cutting (CSS) had been selected ({{mono|{{pslink|G96}}}}), it stays in effect until the end of the program. In operation, the spindle speed increases as the tool near the center of the work to maintain constant surface speed. Similarly, once rapid feed is selected ({{mono|{{pslink|G00}}}}), all tool movements are rapid until a feed rate code ({{mono|G01, G02, G03}}) is selected.
# It is common practice to use a load monitor with CNC machinery. The load monitor stops the machine if the spindle or feed loads exceed a preset value that is set during the set-up operation. The jobs of the load monitor are various:
