    Abstract: Warqe processing is carried out dominantly by women using traditional tools such as a bamboo scraper and wooden plank. The processing practice of warqe into food remained traditional and inefficient. The decortication process through which the separation of fiber and core takes place has been time consuming, much energy demanding and cause drudgery... Show More

    Abstract: Surface quality represented in the primary surface texture is the main parameter when dealing with surfaces in relative rotary and sliding motions. In conventional machining processes, if further quality in surface roughness is required, finishing and superfinishing machining operations are available. In case of extremely high resistive, hard and h... Show More
