METHOD AND APPARATUS FOR CONTROLLING IN-FEED GRINDING Russian patent published in 1999 - IPC

FIELD: machine engineering, machine tool manufacture, namely automatization of processes of in-feed grinding for high-run and gross production. SUBSTANCE: method comprises steps of dimensional intermediate dwelling after rough grinding stage; setting allowance value for final grinding depending upon distribution range of rate of removing allowance and fluctuation of part shape; setting final feed level according to dispersion of time constant of grinding process; setting allowance value for dwelling in proportion to mathematical expectation of time constant of grinding process. Apparatus for performing the method includes pickup of allowance value, amplifier-converter, microcomputer, null balance device, unit for controlling drive of cross feed, cross feed carriage, setter of allowance for final grinding and dwelling, setter of rough grinding speed, unit for determining rate of removing allowance, unit for determining initial dimension and fluctuation of part shape, two electronic switches, setter of allowance for intermediate dwelling, central processor unit, operational memory unit, read only memory, device for inlet-outlet of data, key board. EFFECT: enhanced efficiency of machine tool, high quality of ground parts. 2 cl, 2 dwg
