Characterization of Topography of Cut Surface Based on Theoretical Roughness Indexes

Abstract

The microgeometry of cut surfaces is one important characteristic of surface quality, since it has significant influence on the tribological properties of working surfaces. In addition to the ability to plan the economical effectiveness of cutting and the accuracy of workpieces the ability to plan the quality of machined surfaces has also emphasized importance. This is why the predictability of surface roughness in planning of technological processes is more and more important. More and more opportunities presenting themselves and one of these is the estimation of the expected value of roughness of the machined surface on the basis of the theoretical value of roughness. The paper focuses on the introduction of a method to describe a mathematical relation between the theoretical and the measured roughness indexes in cutting with tools having defined edge geometry, thus the planning may be more accurate.

Minimization Method for 3D Surface Roughness Evaluation Area

“…In cutting, the final surface topography depends on the tool and workpiece material pair, the tool geometry and the kinematic characteristics of the machining procedure. This effect can clearly be observed by studying theoretical roughness parameter values in machining by fixed [3] or rotational tools [4,5]. Therefore, planning the machining conditions and data requires special attention, particularly in finishing operations.…”

Effect of abandonment of cooling and lubrication on surface roughness and cylindricity in turning of steel

“…This includes surface roughness and shape errors and among them, cylindricity deviations. Therefore, not only the effect of cutting data (Kundrak and Felho, 2016;Felho and Kundrak, 2012;Masoudi et al, 2019) but the effect of cooling-lubrication (Masoudi et al, 2019) can be evaluated on such bases as well.…”

Analysis of shape correctness of surfaces of diamond burnished components

“…In the last decade, the researches dealing with the shape correctness [4] and surface roughness of the machined surface [5][6][7], become quicker. More and more papers deal with the examination of residual stresses [8] and changes on the texture [9] taking part on the surface.…”
