ABSTRACT:
A method of efficiently removing material from a workpiece of difficult-to-machine materials. The Z axis machining includes the steps of using a center cutting end mill and forming multiple cylindrical holes having tangent diameters and predetermined depths. Said holes, when formed, leave posts that, when viewed in plan, form stars and cusps. Said stars are then removed by reciprocal movement of said end mill along its Z axis and cusps removed by Z axis machining and/or conventional end milling.
