GEAR-SHAPING MACHINE Russian patent published in 2012 - IPC B23F5/16 

FIELD: process engineering.

SUBSTANCE: proposed machine comprises bed, post, slide with reciprocating tool spindle with shaping cutter secured therein, and table with workpiece spindle. Machine is furnished with radial feed slides, tool spindle main motion transducer, trigger, frequency divider and table drive stepped motor Note here that tool spindle performs continuous feed circular motion while workpiece spindle continuously revolves in synchronism therewith. Note also that, to cut teeth, table may penetrate-withdraw along the line connecting the centers of shaping tool and workpiece at the speed subject to tooth thickness variation along the length and preset frequency of pulses generated by control trigger depending upon aforesaid transducer signals to be fed to table drive stepped motor.
