Topic Method and the device in order to form the hole where it possesses the contour where, the wall of the hole and the like where it possesses the convex form wall or the concave form wall curves in the work piece are offered.SolutionsThe hole h of cone is perforated in work piece 18 by using the abbreviation cylindrical cutting tool 24 which possesses the cutting head diameter which is smaller than apex and bottom diameter of the hole which is formed basically. This method abbreviates corresponds on the inclination where the wall of the hole of the cone where tilt angle of skew of axis of longitudinal direction of the cutting tool is formed is desirable, from normal line of the work piece in plane surface arranges the axis 26 of longitudinal direction of the cutting tool in the specified angle which the offset is done, turns the cutting tool on the one hand, around the principal axis moves with circular route, includes the step which sends the tool to axial direction. In order to produce the hole which possesses curve wall section, tilt angle of skew of axis of longitudinal direction of the cutting tool, is modified during machining job. The device in order to produce that kind of hole in order to adjust the tilt angle of skew of axis of longitudinal direction of the cutting tool in regard to the principal axis, includes the mechanism which is formed.
