FIELD: machine engineering, possibly in metal working plants for grinding blanks with use of automatic devices for controlling feed of grinding disc.
SUBSTANCE: method comprises steps of controlling in-feed and rough feed according to value of sound pressure of acoustic signal corresponding to maximally admissible (according to manufacturing condition) rate of removing allowance. Rate of removing allowance is sustained according to condition of equality of sound pressure value and setting value. When rate of removing allowance achieves predetermined value control process is realized according to rate of removing allowance depending upon allowance value.
EFFECT: enhanced efficiency and stability of grinding process.
