Inventor: KAWAGUCHI KEIJI
IPC: B24B49/00
Filed: 1985-10-31
Abstract: PURPOSE:To prevent production of a taper through compensation for lowering of the cutting quality, by a method wherein a margin under skip is calculated, and when an accumulating value is high, a machining speed is decreased. CONSTITUTION:An initial gauge change rate Gco is previously set. Meanwhile, a margin accumulating computing circuit 18 accumulates a margin DELTAD(j), inputted from a marging computing circuit 15, at each machining completion signal, and an accumulating value IR is outputted to a change rate computing circuit 22. A gauge change rate computing circuit 22 computes a gauge change rate Gco from the initial gauge change rate Gco and the accumulating value IR. According to the set gauge change rate Gc, cutting control is executed. Thus, since, even if under skip, a machining speed is controlled in consideration of the cutting quality of a grindstone 4, an unreasonable force is not exerted on a grindstone shaft 5, correct grinding is executed, and taper is prevented from occurring.
