Influence of the turning process on the distortion of disks for gear manufacture

Abstract

This study presents investigations on the fundamental mechanisms of part distortion during the machining of disks (cylindrical gear base bodies). The work focuses on the effects of machining induced residual stresses and inhomogeneous material removal. In this context the workpiece clamping was investigated as a major impact factor on the distortion. In order to analyze and describe the complex shape deviations, an appropriate distortion characterization method was developed. Since the distortion of disks directly affects the gear wheel quality, the results will help to understand the formation of gear distortion as well as to reduce and compensate it.

Corrosion Behavior of an AISI/SAE Steel Cut by Electropulsing

“…For this purpose, a lot of research has focused on different methods to improve both conventional (CP) and non-conventional (NCP) manufacturing processes by using combinations of CP and NCP in what is referred to as hybrid manufacturing processes. Some examples of these methods are, the use of advanced materials in cutting tools and the use of different types of coated cutting tools [5,6], the effects on cutting parameters on tool life, surface roughness and cutting forces with Cubic Boron Nitride (CBN) tools [7], the application of green-lubrication fluids during metal-cutting processes [8,9], novel metal-cutting strategies that minimize the plastic deformation of the workpiece [10,11] as well as the energy consumption (electrically assisted manufacturing processes show lower consumptions [12,13,14]), different comparisons between exergy efficiency definitions for manufacturing processes [15], study of improvements of energy efficiency of manufacturing processes [16], the use of sustainability methods, predictive, and optimization models for sustainable manufacturing [17], examples for energy savings and resources efficiency in practical examples from metal cutting industry [18], and complex cutting tool geometries that improve the interaction between the cutting tool and the workpiece [19,20].…”
