Research Paper On Surface Roughness

Surface roughness of any solid material will have a significant influence on the macroscopic contact angle measurement on its flat surface, which plays a vital role in various processes such as moistening, spreading, and wetting (23).It is generally accepted that surface roughness parameter of a substrate has an influence on the hysteresis of the contact angle analysis.

Abstract: This paper presents a study on analysis of influences of the surface roughness in Electrical Discharge Machining 90CrSi tablet shape punches with the use of copper electrode. In this paper, 9 experimental runs were designed and conducted by using Taguchi method.

Research Paper On Surface Roughness

The roughness analysis indicates that he fiber surface roughness parameter Sa increases with the deepening of ageing degree. Special attention should be paid on the increase in the surface roughness of insulation paper, as it will aggravate the oil streaming electrification when the paper is applied to the power transformers.

Research Paper On Surface Roughness

It was shown in the paper the influence of finishing cutting regimes, for a given geometry of insert, on surface roughness of turned surfaces on CNC lathe, with higher cutting speeds than those used on conventional machine tools and with very small advances and cutting depths, thus explaining certain phenomena that occur in the cutting process.

Research Paper On Surface Roughness

For the quantification of the surface roughness we have chosen the root mean square roughness factor Sq and other parameters such as Max, Min, Sy, Sssk and Ska. Results are summarized in Tables 2 and 3. As we can see from the results presented in Table 2, the root mean square roughness of plain paper is higher than the one of the printed paper.

Research on Surface Roughness of Hardox Steels Parts Machined by Abrasive Waterjet %K abrasive waterjet machining; Hardox steels; surface roughness; regression model %X This paper presents an experimental investigation on the abrasive waterjet machining (AWJM) of Hardox steels.

This paper looks specifically at the effects of differing build parameters on the surface roughness of down-facing surfaces, in particular when the parameters only change within the plane of the.

This paper presents an experimental investigation focused on identifying the effects of cutting conditions and tool construction on the surface roughness and natural frequency in turning of AISI1045 steel. Machining experiments were carried out at the lathe using carbide cutting insert coated with TiC and two forms of cutting tools made of AISI 5140 steel.

Cut surface quality is a very important characteristic of laser cutting that ensures an advantage on other contour cutting processes. This paper gives results of the experimental research referring to the determination of surface indicators obtained by laser cutting.

Silver nanowire transparent electrodes are a promising alternative to transparent conductive oxides. However, their surface roughness presents a problem for their integration into devices with thin layers such as organic electronic devices. In this paper, hot rollers are used to soften plastic substrates with heat and mechanically press the nanowires into the substrate surface. By doing so.
