Surface roughness measurement is an important one in any manufacturing next to dimensions. In this investigation, a vision system and image processing tools were used to develop reliable surface roughness characterization technique for Electrical Discharge Machined surfaces. A CMOS camera with red LED light source were used for capturing images of EDMed surfaces. A separate signal vector generated for all the images from its image pixel intensity matrices. The mean, skewness and kurtosis were obtained from the signal vector. The mean, skewness and kurtosis of the images signal vector correlates very well with the stylus measured hybrid roughness parameters Rda and Rdq. Hence the technique may be preferred for online surface roughness characterization of Electrical Discharge Machined (EDMed) surfaces.

In recent automotive era, natural fibre reinforced with thermoset polymer composites have been incorporated by automotive industries especially for interiors, car body panels, dashboards, headliners etc. Natural fibres offer many affirmative qualities such as less weight and cost, especially in reduction of carbon di-oxide which is a major threat to the planet from the automotive sectors. The current work deals with the study of the potential usage of mineral powder (industrial by-product) in polymer. In this paper, hybrid composites with natural fabrics reinforcements and mineral powder as filler to matrix material are developed. The mineral powder used as filler is silica fumes which is a by-product of industries. The hand lay-up methodology is employed to fabricate the composite. The composites with and without mineral filler material are developed. The mechanical properties of the composites are assessed. The mechanical properties of composites with and without mineral filler are compared and their result shows that with addition of filler material, the mechanical properties of the composites are affected. Results disclose that loading of silica fumes increases the…
