A complete algorithm for designing planar fixtures using modular components
AbstructCommercially available modular fixturing systems typically include a lattice of holes with precise spacing and an assortment of precision locating and clamping modules that can be rigidly attached to the lattice. Currently, machinists manually design a suitable arrangement of these modules to hold a given part. This requires expertise and can delay production. Futhermore, a machinist ma...
متن کاملParallel Simulation of Bevel Gear Cutting Processes with OpenMP Tasks
Modeling of bevel gear cutting processes requires highly flexible data structures and algorithms. We compare OpenMP3.0 tasks with previously applied approaches like nesting parallel sections and stack based algorithms when parallelizing recursive procedures written in Fortran 95 working on binary tree structures.
متن کاملAn 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 کاملGear tooth designing with cubic Bézier transition curve
This paper describes the method of designing a Spur Gear Tooth using an S-shaped transition curve joining two tangent circles. For this purpose a single segment of cubic Bézier curve has been used as a transition between two tangent circles of same diameter. This transition curve not only maintains G Hermite like conditions but also guarantees not more than one inflection point in its curvature...
متن کاملFZG Gear Efficiency and Pin-on-Disc Frictional Study of Sintered and Wrought Steel Gear Materials
Load-dependent power loss is a major contributor to power loss in gear transmission systems. In this study, pin-on-disc frictional and FZG efficiency experiments were conducted with powder metallurgy (Distaloy AQ ? 0.2 %C) and wrought material (16MnCr5) combinations. The gear mesh torque loss from gear efficiency tests and the friction coefficient from the pin-on-disc tests were then compared. ...
