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.
Highlights
Basing on the achievements of mathematical statistics and classical methods of experimental design, Taguchi developer his own methods of experimental design and results analysis [1,2,3,4]
The information mentioned in the introduction and observed in last years technology the tendency to eliminate of abrasive machining methods for machine parts operating under sliding friction conditions caused that problems connected with design and manufacture of device for shaft roller burnishing are present-day problems in Department of Manufacturing Processes and Production Engineering in Rzeszow University of Technology
This paper presents attempt of determination of machining process selected parameters influence on achieved surface roughness of cylindrical outer elements after roller burnishing
Summary
Basing on the achievements of mathematical statistics and classical methods of experimental design, Taguchi developer his own methods of experimental design and results analysis [1,2,3,4]. The roller burnishing is one of the most often used methods of burnishing of cylindrical outer surfaces. 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. For mentioned above elements ball burnishing or slide diamond burnishing are usually used. These finishing methods are characterized by very small productivity and whenever possible the roller burnishing should be used because of its this higher productivity.
