Abstract
An apparatus for controlling operation of a lapping, honing or polishing machine comprising at least one working disk having an abrasive means for honing, lapping, or polishing the surface of a work-piece and adapted to be driven by a variable working disk drive, at least one planetary gear member for carrying said work-piece and having teeth at its outer periphery, and inner and outer gear members in driving engagement with said planetary gear member, at least said inner gear member being driven by a variable inner gear member drive, said apparatus including a control stage for providing a control signal to said working disk drive and said inner gear member drive for controlling desired drive speeds, the improvement of which includes a computer 44 connected to said control stage for generating input signals for said control stage, which computer is arranged to calculate the speed of said inner gear member drive and the speed of said working disk drive by the following formulas: EQU n.sub.L =K.sub.L .multidot.n.sub.M EQU n.sub..DELTA. =n.+-.K.sub.UL .multidot.n.sub.M' wherein K.sub.L and K.sub.UL are constants of the rolling geometry of said gear members and n.sub.L representing th…
