Abstract
Generating cutting processes for producing bevel gears and employing a single rotary disc cutter (36) wherein a portion of the generating cutting process effectively includes a reduction (38) of the workpiece roll angle (40) during generating thereby reducing or eliminating cutting action on the clearance side (42) of the rotary disc cutter.
Claims13
A method of rough manufacturing a gear tooth on a workpiece, said manufacturing being carried out by a cutting tool having a plurality of cutting blades with each of said cutting blades having a cutting edge and a clearance edge, said method comprising:
- rotating said cutting tool,
- bringing the rotating cutting tool and said workpiece into contact with one another,
- rotating said workpiece,
- moving said cutting tool relative to said workpiece to define a generating roll for generating said gear tooth,
- wherein said rotating of said workpiece comprises rotating the workpiece in a first direction from a start roll position to an end roll position, and wherein said workpiece is rotated at a first rate of rotation less than a theoretical rate of rotation beginning at said start roll position and ending prior to said end roll position,
- or,
- wherein said moving of said cutting tool comprises moving the cutting tool in a first direction from a start roll position to an end roll position, and wherein said cutting tool is moved at a first rate of movement greater than a theoretical rate of movement beginning at said start roll position and ending prior to said end roll position.
