Method for cutting complex tooth profiles in a cylindrical, single-screw gate-rotor

摘要

A method for manufacturing precision gate-rotors and gate-rotor supports for a single-screw mechanism by cutting the complex tooth profiles in a cylindrical gate-rotor blank. The cylindrical blank is rotated about its center axis as a cutting tool is translated in a fixed two-axis plane, one axis being the centerline of the cylindrical blank and the second axis being a line extending radially therefrom. This process may be carried out by a multi-axis, numerically controlled milling machine.
