摘要
PROBLEM TO BE SOLVED: To provide a long-lived sintered hard alloy-made end mill for cutting a workpiece stably, manufacturing a tool and regrinding the tool easily with a reduced manufacturing cost, dispersing cutting resistance to suppress the occurrence of chattering vibration, and setting the allowable rotational speed to a high speed in highly efficient machining such as mold machining and parts machining, and to provide a cutting method using the end mill.;SOLUTION: In the sintered hard alloy-made end mill, when a first gash angle is set at 15-35 degrees, a second gash angle is set at 40-60 degrees, and one corrugated outer peripheral blade is set as a reference shape outer peripheral blade, an amount of phase shifting of at least one corrugated outer peripheral blade among adjacent corrugated outer peripheral blades from phases of the reference shape outer peripheral blades arranged at an equal interval by a value obtained by dividing a wave pitch by the number of blades is zero, and amounts of phase shifting of other corrugated outer peripheral blades are uneven. In a cutting method, at least two types of cutting selected from vertical feed cutting, cross-feed cutting, and oblique cutting are continuously performed.;COPYRIGHT: (C)2011,JPO&INPIT
