PURPOSE:To make the machining time more stable while keeping the surface roughness of the inner surface of a machined hole appropriate in honing work. CONSTITUTION:When the machining time exceeds the target machining time, the machining pressure of a grinding wheel 11 to the inner surface of a machined hole 1 is heightened so as to shorten time to machine the inner surface of the machined hole 1 into the target surface roughness. When the machining time is less than an objective machining time, the machining pressure of the grinding wheel 11 to the inner surface of the machined hole 1 is lowered so as to prolong time to machine the inner surface of the machined hole 1 into the objective surface roughness. In either case, the machining time approaches the objective machining time. |
