The effect of the material roughness on the detachment of the dried maltodextrin film was evaluated comparing glass plates with two different surfaces (smooth and sandblasted glass). Results indicate that the higher the surface roughness, the drier should the film be, in order to promote selfdetachment at the same temperature conditions.
The effect of machining debris settling on the workpiece surface is responsible for the poor surface roughness recorded during dry wire-EDM as shown in Fig. 2. CONCLUSION The surface integrity of SUS 304, austenitic stainless steel during dry and wet wire-EDM as well as the effect of pulse current and gap voltage were experimentally investigated and analyzed.
The surface roughness of wood products is depending on many factors related both towood properties and wood working operational parameters. Probably this is the reason why there areno generally
01-04-2020· The sample material used in the study is a Y-TZP bio-ceramic (Blue Whale Ceramic Technology Co., Ltd, China), the material properties of which are listed in Table 1.The size of the sample is 30 × 30 × 5 mm 3.Plane surface grinding and polishing were applied to the samples to prepare surfaces with different grades of surface roughness and surface texture.
THE EFFECTS OF MACHINING PARAMETERS ON SURFACE ROUGHNESS OF MATERIAL EN-31 IN EDM USING COPPER ELECTRODE Mr. Kurri Rohan Ramesh M.E. Scholar, Department of Mechanical Engg. BIGCE, Solapur University, Maharashtra, India Prof. Jagtap Satish Tukaram Associate Professor, Department of Mechanical Engg.
01-12-2010· Experimental results evidencing the impact of surface roughness on contact angle have been found in previous research . Fig. 8 is the schematic diagram of bubble coalescence on surface of different roughness. As can be seen, bubbles of bigger mean diameter are formed on tool electrode of greater surface roughness, thus forming a thicker gas film.
A procedure has been developed to predict the effects of roughness and Reynolds number on the change in efficiency from a model or baseline to a prototype pump (efficiency scaling). The analysis of individual losses takes into account different roughnesses of impeller, diffuser/volute, impeller side disks, and casing walls in the impeller side rooms.
Surface roughness varies greatly with an increasing number of laser pulses applied. Fig. 11 presents results of analysis of smooth samples (A) (initial roughness, before cleaning of 2.28-2.49 m). The relationship can be divided into two zones the higher rate of increase of surface roughness in Zone 1 was probably caused by the removal of paint, while the lower increment in Zone 2 could
01-10-2019· The effects of drying temperature on the films' structural, thermomechanical, mechanical and water barrier properties were investigated. Microstructural observations indicated that zein particles were homogeneously dispersed in KGM continuous matrix, and the blend film dried at 60 °C showed the most compact and smooth surface.
Surface roughness often shortened to roughness, is a component of surface texture.It is quantified by the deviations in the direction of the normal vector of a real surface from its ideal form. If these deviations are large, the surface is rough; if they are small, the surface is smooth.
The evaluation of surface roughness is increasingly valued in the manufacturing industry. To study the surface roughness, you need to use a special machine, named: surface roughness measuring instrument. Most of the correct and complete surface roughness measurement methods, although they use a dedicated measuring machine, but in some cases, for quick and low-cost operation, you can
The effect of machining time on the surface roughness of the machined specimens at different machining temperatures is shown in figure (5). Eng. &Tech.Journal, Vol.33,Part (A), No.6, 2015 Influence of Machining Parameters on Surface
Effects of surface inactivation, high temperature drying and preservative treatment on surface roughness and colour of alder and beech wood October 2005 Applied Surface Science 252(2):430-440
The permissible blade surface roughness for hydraulically smooth boundary layer conditions in modern high pressure ratio compression systems is derived from experimental data achieved with blades produced by grinding, electrochemical machining and forging. A correlation between the effect of technical roughness and sand type roughness is given.

The topography of the fibers surface was investigated by atomic force microscopy and tentatively related to the measured nucleation ability. While a general effect of surface roughness on lowering the heterogeneous nucleation energy barrier can be deduced, relevant deviations can be observed, in particular for carbon and SC PLA fibers.
