In order to investigate the influence of cutting condition to the wall precision in finishing process of high hardened steel, we conducted some experiments changed cutting parameters(cutting speed Vc, feed rate fz, axial depth of cut ap ). The result is that the most impact factor is the axial depth of cut. It was few changed of the wall precision in changing Vc and fz. On the other hand, by decreasing ap, the cutting force is tend to be reduced dramatically. Therefore, we surmise that the tool deflection is suppressed, and the wall deflection is also improved. The result compared with cutting direction is that the wall precision machined by up cut milling is higher than down cut milling. In the case of small ap, when ap and flute length of the endmill is the same, it is possible to machine the higher wall precision than the machining by using the long flute length endmill, without contacting the cutting edge of the tool shank side with the wall surface.
