To perform higher accurate honing work by facilitating correction work relating to an objective internal diametric value, in the case that an internal diameter of a machining hole is deviated to exceed a permissible range relating to a value aimed at by an internal diameter of a machining hole.
In the case of performing honing work while measuring an internal diameter of a machining hole by an internal diameter detection means 27 provided in a honing head so as to obtain an objective value of the internal diameter of the machining hole, when honing work of a plurality of workpiece is continuously performed, an internal diameter mean value after ending machining in each specified number of workpieces in accordance with a machining order is successively calculated as a moving average by a moving average calculating means 31. In the case of calculating this moving average value, a required specified number of workpieces is a number making the moving average value equal to a rood temperature change detected by a temperature detection means 35, based on the moving average value calculated by this number of workpieces, the target value of the machining hole internal diameter is corrected by a correction means 37.
