Abstract:
A method for manufacturing a masking tool (60) for use in combination with a shaped-workpiece in the manufacture of a precision gear (10), comprising the steps of:a) forming an accurate representation of the shaped workpiece (30.sub.S) defining tooth space surfaces (68) between adjacent gear teeth (12);b) preparing a surface of a flexible back-plate (64) so as to promote adhesion;c) situating said flexible back-plate (64) proximal to the gear teeth (12); andd) forming a compliant material between said flexible back-plate (64) and the tooth space surfaces (68) so as to produce a plurality of compliant masking segments (62) each having a surface geometry complementary to the respective tooth space surface (68) and defining an open-ended channel (70) between adjacent masking segments (62).
