The principle of profile modified face-gear grinding based on disk wheel
Mechanism and Machine Theory, 2013Abstract In view of the disadvantages of the current grinding method for profile modified spur face-gear, a progressive grinding method is developed. The third action principle of modified spur face-gear driving and the mathematical model of parabolic rack cutter, spur gear cutter, disk wheel and modified spur face-gear are established, based on the ...

To reduce form grinding errors, this paper proposes a free-form flank topographic correction method based on a five-axis computer numerical control (CNC) gear profile grinding machine. This correction method is applied not only to the five-axis machine settings (during grinding) but also to the wheel profile (during wheel truing).

In the case of generation grinding of the higher order modification gear surface, there are main problems such as difficulty in solving the 3D meshing equations and complexity of expressing the profile of grinding worm. In this study, an indirect generating method is proposed to calculate the profile of grinding worm by applying a virtual rack-cutter ...

A flank correction methodology for a five-axis CNC gear profile grinding machine
Mechanism and Machine Theory, 2012Abstract Form grinding is the most popular finishing process for large-size gear because of its high accuracy, efficiency, and flexibility in tooth flank modification. Theoretically, this tooth flank topographical modification is calculated using loaded tooth contact analysis (LTCA), which takes into account the gear tooth, shaft, and housing ...

Gear profile grinding with metal bonded CBN tools
Production Engineering, 2014For a high durability of stressed gears profile accuracy, compressive residual stress and a high surface quality of the ground gear flanks is required. In this context the suitability of metal bonded cubic boron nitride (CBN) tools for discontinuous profile grinding of gears is examined.

A Mathematical Model for Grinding a Stick Blade Profile to Cut Hypoid Gears
Journal of Mechanical Design, 2019Abstract Cutter head with multiple stick blades is widely used in the mass production of hypoid and spiral bevel gears because they allow more blades per revolution of the head cutter. However, the stick blade geometry for a head cutter that is used in face-milling and face-hobbing methods to produce hypoid and spiral bevel gears is ...
