Gear hobbing is a common method of manufacturing high precision involute gears. The thorough knowledge of the developing cutting forces and the wear of the cutting tool are of great importance in order to produce helical and spur gears as they influence the cost of the manufacturing process and the quality of the produced gear. HOB3D is a simulation code that enables users to simulate the proce...

A planar spiral called Generalized Log Aesthetic Curve segment (GLAC) has been proposed using the curve synthesis process with two types of formulation; ρ-shift and κ-shift. Both methods were carried out by extending the formulation of Generalized Cornu Spiral (GCS) in a similar manner to the Log Aesthetic Curve (LAC). The family of GLAC comprises of planar curves of high quality such as GCS, L...

Elastohydrodynamic lubrication (EHL) modelling plays an important role in engineering design and analysis since a number of important mechanical components operate under EHL conditions. In this paper methods are presented for solving both line and point contact cases using multiphysics software. The advantages, and the overheads, of using such an approach over developing highly specialised, bes...

Robots are increasingly performing human work as manufacturing is automated. Accordingly, the use of precision speed reducers has become essential for achieving precise control of the robot arm position. Curved tooth profiles, such as cycloid or involute tooth profiles, are generally used in precision speed reducers. Speed reducers with cycloid tooth profiles, which enable high precision contro...
