Study on design of taper shaped skiving cutters for internal gears (Taper shaped cutter ground with trapezoidal wheels used for pinion cutter grinding)

Nihon Kikai Gakkai ronbunshu, 2017
Taper shaped skiving cutters are commonly used in gear skiving because they provide clearance angles under a simple gear arrangement and they could have lower cutting resistance than cylindrical skiving cutters. Their tooth flanks are generally ground by

Sensing creativity: the role of materials in shoe design [PDF]

, 2017
This essay is about designing and making shoes. Classical notions of design present it as a process whereby drawing is prefigured by a concept. This understanding overlooks the importance of materials, which through their particular technical, functional,

Study on the skiving process of an internal gear (Effects of axial feed rate on gear accuracy)

Nihon Kikai Gakkai ronbunshu, 2015
In this paper, study on the effects of axial feed rate on the gear accuracy is discussed. First, geometrical model of a skiving process was introduced. The model was assumed that the cutter was perfectly made and perfectly assembled to the skiving rig (i.

Calculation of skiving cutter blade [PDF]

AIP Conference Proceedings, 2018
The gear skiving method is a kind of gear machining technology with high efficiency and high precision. According to the method of gear machining, a method for calculating the blade of skiving cutter in machining an involute gear is proposed. Based on the principle of meshing gear and the kinematic relationship between the machined flank and the gear ...
