ABSTRACT:
A feed speed control system for use in numerical control systems or the like, in which a set feed speed can be adjusted through a simple structure. The control system includes a memory circuit for storing a plurality of numerical values corresponding to feed speeds, a command circuit for issuing a command indicative of a prescribed numerical value from among the plurality of numerical values, an arithmetic circuit for incrementing or decrementing a numerical value read from the memory circuit in response to an output pulse from manual operation device, and a pulse generating circuit for generating pulses of a frequency which is proportional to an incremented or decremented numerical value from the arithmetic circuit.
