Fused Filament Fabrication (FFF) or Deposition Modelling (FDM) three-dimension (3D) printing are rapid prototyping processes for workpieces. There many factors which have a significant effect on surface quality, including bed temperature, speed, and layer thickness. This empirical study was conducted to determine the relationship between above-mentioned average roughness (Ra). Workpieces of cyl...

Surface roughness is a factor of great importance in the evaluation of cutting performance and it plays an important role in manufacturing processes. Performance parameters such as cutting force, cutting temperature, vibration etc. can be used to predict surface roughness. It is expected that more accurate prediction would be possible if these factors are considered collectively with cutting pa...

This paper presents a new approach for surface roughness (Ra) prediction during milling by using dynamometer to measure cutting forces signals and cutting conditions. End milling machining process of hardened die steel with carbide end mill, was modeled in this paper using the adaptive neuro fuzzy inference system (ANFIS) to predict the effect of machining variables (spindle speed, feed rate an...

Now a days a manufacturing system is oriented towards higher production rate, quality, and reduced cost. Surface roughness is an index for determining the quality of machined products and is influenced by the cutting parameters. In die manufacturing industries Surface roughness of dies are considered as a vital quality characteristic. For the complex shapes of a die, three dimensional machining...

Surface roughness has been considered as an important influencing factor for cell response. The aim of this study was to find out whether MC3T3-E1 cells, a mouse osteoblast-like cell line, can sense the amplitudes of surface topography of titanium alloy (Ti6Al4V), and if surface-dependent cell morphology would be presented on the substrata with varied roughness. A series of polished samples (Ra...

In this paper the authors describe the results of experiments for surface roughness image acquisition and processing in order to develop an automated roughness control system. This implies the finding of a characteristic roughness parameter (for example Ra) on the bases of information contained in the image of the surface. To achieve this goal we use quasi-fractal characteristics and fuzzy clus...

objective: increased enamel surface roughness following orthodontic bracket debonding leads to increased plaque accumulation and enamel decalcification. therefore, different methods are employed to achieve smoother enamel surfaces after bracket debonding. this study compared enamel surface roughness following orthodontic bracket debonding and composite resin removal using white stone and tungst...

In order to meet the clinical requirements of spine surgery, this paper proposes the fabrication of the customized template for spine surgery through computer-aided design. A 3D metal printing-selective laser melting (SLM) technique was employed to directly fabricate the 316L stainless steel template, and the metal template with tiny locating holes was used as an auxiliary tool to insert spinal...
