Development of Gear Hobbing Fixture Design for Reduction in Machine Setting Time
نویسنده
چکیده
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. There by, reducing company’s cost & time. The design was checked and validated for safety under the action of cutting forces.

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 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 کاملReliability Allocation for CNC Machine Based on Improved Fuzzy Analytic Hierarchy Process
Abstract Reliability allocation is the key issue of reliability designing. CNC machine is a complex product. There are many influence factors of reliability allocation. A part of them cannot be accurately measured but be evaluated by the experts. Therefore it’s difficult for reliability allocation. In this paper, we consider a variety of criteria for conducting reliability allocation. A method ...
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...
