Abstract

The invention comprises a computer aided program for milling machine to machine precise concave and convex surfaces within a metal block to form the base section of a turbine blade called the root section (1). The root section (1) of the turbine blade is designed to fit within precise tolerances upon a circular rotor.
Because of the curvatures of the mating surface of the root section and the mating section of the circular rotor, the machining of the root section of the turbine blade requires convex movements of the form cutter tool (9) and rotating of the rotary table (7) which holds the turbine blades. The invention teaches a method of determing machining instructions for machining of a workpiece using a machine having a cutter (9), the surfaces of the workpiece being defined by a plurality of programmed instructions obtained by trigonometric analysis of the required surface curvatures.
