Application of function of quality losses G. Taguchi for study of roller burnishing parameters

Abstract: The results of roller burnishing parameters analysis with selfacting feed are presented in this paper. Method of parameter process design based on the quality losses G. Taguchi function was applied. The following controlled parameters were assumed: Ra – roughness parameter before roller burnishing process, w interference between a roller and a burnished sample. k – multiplication factor of each sample point deformation, V – burnishing velocity. The following factors were assumed as process disturbances: treated material hardness and lubrication of burnished surface. Basing on experimental results it was found that strongest influence (in tested range of parameters variations) on roller burnished surface roughness has initial surface roughness and burnishing velocity. These factors also showed have the smallest resistance to process disturbances. 1 Theoretical introduction Basing on the achievements of mathematical statistics and classical methods of experimental design, Taguchi developer his own methods of experimental design and results analysis [1-4]. Taguchi created among the others theory of quality losses function based on experimental design. Decrease in the number of experiment with respect to traditional experiment is the fundamental advantage of Taguchi’s approach. However selection of suitable factors combination causes controversy. The roller burnishing is one of the most often used methods of burnishing of cylindrical outer surfaces. Usually it is used for cold hardening. Smoothness burnishing is the other application. This kind of burnishing is applied when required shape and dimensional accuracy was obtained in previous treatment and very good smoothness of burnished surface is required. Smoothness roller burnishing is used to finish machine parts in which grinding pollutions in surface layer are unacceptable or for elements which can’t be finished with too strong forces. For mentioned above elements ball burnishing or slide diamond burnishing are usually used. However these finishing methods are characterized by very small productivity and whenever possible the roller burnishing should be used because of its this higher productivity.

Investigation on the Effect of Roller Burnishing Process on the Surface Quality and Microhardness of Cu-Zn-Al Sma Alloys

Abstract: Burnishing is a plastic deformation process that can be used to finish surfaces by plastic deformation of surface irregularities. The burnishing is chipless machining which can be used to improve the surface roughness and surface hardness on any metal work piece. The purpose of the research was to demonstrate the roller burnishing process on Cu-Zn-AL to enhance the mechanical properties of Cu-Zn-Al shape memory alloy and improve surface quality and surface microhardness. The experiments were carried on Cn-Zn-Al SMA using CNC turning machine with various spindle rotations, feed rates and depth of penetration, where a roller burnishing tool was designed and manufactured to be used in this investigation. It was found that the surface roughness and microhardness on various Cu-Zn-Al SMA were improved by high spindle speed, The best results were attained at 212 N burnishing force, 50 mm/min feed rate and 1120 rpm.

Parametric optimization of roller burnishing process for surface roughness and surface hardness

Abstract: Now a days, manufacturing industry expected more service life of the components without increasing the production cost This led to development improvised and versatile manufacturing processes that address these expectations The service behavior and life of the components depend mostly on the surface properties For this reason, significant attention has been paid to the post-machining operations, because the conventional machining processes like turning, milling etc produce surfaces with inherent irregularities and imperfections So there is need for a surface finishing operation that nullifies these irregularities Burnishing is one of the surface finishing process, which does not involve material removal, but improves the surface properties by deforming the surface plastically Here SS410 steel is used for making shafts with good surface finish and hardness by the roller burnishing process The present study aims to achieve high performance of roller burnishing machine, experiments is carry out to find effect of input parameter on output performance parameter The experimental data will be optimizing by full factorial methodology, and conclude optimal set of parameter by Response surface methodology or Regression analysis
