Machining quality has been improved with the development of cutting tools. However, it is difficult to obtain a high degree of quality in machining a deep pocket with a long end mill, since machining accuracy is mainly dependent on the stiffness of the cutting tool and tool holder. To improve machining quality in machining a deep pocket using an end mill, the performance by cutting condition compare with others. Owing to this problem, it is necessary to select suitable tool and holder in the deep pocket machining. In this study, the hydraulic holder for the high speed machining is introduced and the performance of that is compared with others according to cutting conditions. The cutting parameters involved were; slenderness ratio in the range of 3 to 6 (L/D), radial depth of cut from 0.01 to 0.05 ㎜. Cutting force and surface roughness, feature precision were observed during the experiment to investigate cutting state.

The appointed date of a delivery was shorten by high speed machining in shoe-mold. However, it is difficult to obtain a high degree of quality in machining shoe-mold with a great variety of free-surface. Also, it have needed a many process. To improve machining quality process in machining a shoe-mold ,the performance by a speed control. For the high speed machining of a woodcut, process was reduced. We'll be machining a spike model for master shoe-mold machining. Cutting speed control must be used in shoe-mold of a delivery shortening
