Gears

Gear hobbing, as any cutting process based on the rolling principle, is a signally multiparametric and complicated gear fabrication method. Although a variety of simulating methods has been proposed, each of them somehow reduces the actual three-dimensional (3D) process to planar models, primarily for simplification reasons.

Gear shaping is a multipoint machining process for generating teeth by a reciprocating cutter. Gear shaping is one of the most versatile of all gear cutting operations. This cutting process uses a gear-shaped cutter that is reciprocated and rotated, in relationship to a blank, to produce the gear teeth. Cutters rotate in timed relationship with the workpiece. Finally Gear Shaping produces internal gears, external gears, and integral gear-pinion arrangements.

The Power Skiving software simulates the gear manufacturing process of Power Skiving. The software is implemented in a commercial CAD environment which ensures increased accuracy of the simulation. The main functionality includes the calculation of a gear gap and the undeformed chip geometry as well as the cutting forces produced during the process.
