摘要
PROBLEM TO BE SOLVED: To solve various problematic points in the past and shorten a die machining time, by remarkably increasing a rotational speed and a feed speed of a cutting tool, also reciprocating a feed program of the tool. ;SOLUTION: A heat resistant tool, for instance, a single small diametric ball end mill 12 formed of cBN is rotated at a 5 to 200,000rpm high speed and reciprocated horizontally at a 10 to 100m/min high speed, the ball end mill is laterally moved in both end parts of reciprocating motion by a prescribed cutting amount in a horizontal surface to a direction orthogonal to a reciprocating direction, and cut by the same depth of cut, in the same surface and is vertically fed in a perpendicular direction by a prescribed depth of cut, so as to work a die shape by a high speed rotating/reciprocating motion of the single small diametric ball end mill.;COPYRIGHT: (C)1997,JPO
