An Innovative Way of Designing Gear Hobbing Processes
In order to shorten production time, it is wise to use simulation tools at every step of product development. Simulation tools can help avoid iterative steps based on trials and minimize development time—as well as costs. Along with existing WZL software packages (Refs. 1–2), a software simulation tool for gear hobbing has been in development for several years—i.e., PARTApro. Gear hobbing is on...
متن کاملHob 3 D : A Novel Gear Hobbing Simulation Software
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...
متن کاملCAD-based simulation of the hobbing process for the manufacturing of spur and helical gears
Targeting an accurate and realistic simulation of the gear hobbing process, we present an effective and factual approximation based on three-dimensional computer-aided design. Hobbing kinematics is directly applied in one gear gap. Each generating position formulates a spatial surface path which bounds its penetrating volume into the workpiece. The three-dimensional surface paths generated from...
متن کاملDevelopment of Gear Hobbing Fixture Design for Reduction in Machine Setting Time
The design of a fixture depends a lot on the designer’s expertise and experience and hence no solution is optimal or near optimal for a given workpiece. For a Gear hobbing fixture also there are multiple designs possible. This paper is about redesigning of a hobbing fixture to make it common for the other gears’ manufacturing and reduce the no of settings of the fixture on the hobbing machine. ...
متن کاملNew ANSI/AGMA Accuracy Standards for Gears
Time for a Change For many years, the U.S. system of gear accuracy tolerances has been provided by AGMA 2000-A88, Gear Classification and Inspection Handbook. This document has been commonly used for gear accuracy specifications in contractual agreements for vendor-supplied gears. Also, it has often been used as the basis of internal company gear tolerance systems. The material within AGMA 2000...
