Document Type and Number:
Japanese Patent JP4016426
Kind Code:
B2
Abstract:
A method and apparatus for producing conical holes in a workpiece by using a substantially cylindrical cutting tool having a cutting head diameter essentially smaller than the top and bottom diameter of the hole to be formed. The method comprises the steps of positioning the longitudinal center axis of the cutting tool at an angle, which is offset from a normal to a flat surface of the workpiece such that the inclination of the longitudinal axis of the cutting tool substantially corresponds to the desired inclination of the wall of the conical hole to be formed, rotating the cutting tool about its longitudinal center axis, moving the cutting tool in a circular path about a principal axis corresponding to the longitudinal center axis of the hole to be machined, and feeding the cutting tool in its longitudinal direction towards and into the workpiece.
