METHOD OF CONTROLLING PROCESS OF CIRCULAR FEED-IN GRINDING AT CYCLIC OPERATIONS Russian patent published in 1995 - IPC

FIELD: machine engineering. SUBSTANCE: method is being performed with use of allowance taking off rate as a value to be controlled and a feed-in rate as a controlling value. The method comprises steps of grinding at a stage of feed-in with a constant rate of feed-in, whose value is being determined according to conditions of achieving at a time moment of termination of the feed-in process a maximum rate of the allowance taking off, at which in a surface layer of a blank to be ground a burning layer of metal is being formed and propagated on a part of the allowance; at a stage of main taking off the allowance decreasing the rate of the feed-in according to a linear law on a base of conditions, providing a burning-free rate value of metal taking off at a time moment of operation cycle termination, at which a depth of burning layer propagation achieves a limit boundary of the predetermined allowance and the whole allowance has been ground. EFFECT: enhanced accuracy of controlling. 1 cl, 3 dwg
