Numerical controller with function of selecting spindle according to program

Abstract

A numerical controller capable of easily selecting and designating a spindle to be controlled according to a command for the spindle. A spindle ID for designating a spindle to be controlled is given to be associated with a command for the spindle in a machining program. When an analysis/operation section reads the spindle ID, it transmits the commanded spindle ID to spindle selection processing. Then, the commanded spindle ID is collated with spindle ID parameter setting information to determine the spindle to be controlled and spindle control processing is connected to its corresponding one of the spindle control interfaces. Based on the command for the spindle, the spindle control processing is performed to control the selected spindle through the connected spindle interface. Feedback signals may be inputted and processed by spindle feedback signal processing in the same manner.
