State-of-art-review of electrochemical honing of internal cylinders and gears

Abstract: This paper is an attempt to present a state-of-the-art review of two major applications of electrochemical honing (ECH) for internal cylinders and gears, which are the most commonly used parts in numerous engineering applications. ECH is a hybrid process of electrochemical machining (ECM) and mechanical honing, combining the fast material removal capabilities of ECM and controlled functional surface generating capabilities of mechanical honing in a single operation. ECH is a precision micro-finishing process capable of producing excellent surface quality having a cross-hatch lay pattern required for lubricating oil retention, compressive residual stresses required for the components subjected to cyclic loading, and completely stress-free surfaces. Furthermore, it provides these benefits productively. It makes ECH an ideal choice for superfinishing, improving the surface integrity, and increasing the service life of the critical components such as internal cylinders, transmission gears, carbide bus...

Optimization of Gear Tooth Surfaces

Abstract: During the evolution of gearboxes, unwanted noise has been one of the most discussed subjects. Increasing demands on weight reduction and compactness of gearboxes, while preserving the same torque capacity, require optimal design of all parameters involved. Quiet running is especially desirable in a modern automotive gearbox. The very complicated geometry of helical gears, engenders the problem of a multi-variable optimization procedure. Errors of the microform as well as the macroform of the gears highly influence the sound activation. Effects of the macroform have been studied by many researchers and are widely known and predictable. Normally, finishing processes, such as grinding and honing, are used to achieve the predicted macroform of a gear tooth. As a consequence of applying these processes, the microform of the tooth is accomplished. This paper is concerned with the characterization of the gear tooth surfaces obtained with such processes. The characterization is performed with respect to the surface functional properties. These parameters which are interesting due to the noise activity, were identified when the literature available in the field of interest was reviewed. 3D measuring technique, form removal, functional filtering, and 2D spectral density analysis have been utilized in order to extract this information as surface functional parameters. Since the main aim of this paper is to discuss how to produce gears with optimal noise consequences, the principles of RZP-grinding, Fassler honing and Hurth green-shaving are discussed. During this work, the most significant process parameters have been identified utilizing two-level fractional factorial experiments, based on 3D evaluation of surfaces. The parameters identified together with the process principles were then used to predict the surface characteristics. Optimal strategies concerning all processes for production of low noise gears are suggested. The validity of arguments and results regarding the RZP-process was examined, while gears from a real manufacturing shop-floor were evaluated.

Life Cycle and Sustainability of Abrasive Tools

Abstract: This monograph focuses on abrasive tools for grinding, polishing, honing, and lapping operations. The book describes the life cycle of abrasive tools from raw material processing of abrasive grits and bonding, manufacturing of monolithic or multi-layered tools, tool use to tool end-of-life. Moreover, this work highlights sustainability challenges including economic, environmental, social and technological aspects. The target audience primarily comprises research and industry experts in the field of manufacturing, but the book may also be beneficial for graduate students
