Tobacco cutting machine knives (MK) are circular disk or conventional rectangular shape,MK & ancillaries are modular construction for ease of maintenance. Theabrasiveness/corrosiveness of tobacco decreases knife sharpness, causing irregularities inquality of cut tobacco & machine blockages. MK & ancillaries have to be regularly replacedwith reconditioned/new parts causing machine down times & fewer cigarettes being produced.Conventional tobacco cutting MK & wear parts are manufactured from tool steel, stainless &mild steel. The cutting knife & ancillary parts tool life are short, lasting from a little as 4 hrsto a maximum of 48 hrs depending on type of tobacco.The study involves exploration of the tobacco cutting machine market investigating themanufacture of MK & ancillaries. The company hope to develop a unique powder met basedmaterial, specifically formulated to resist corrosion/wear of cutting tobacco. This uniquepowder met material will be used in conjunction with a unique manufacturing method. Theproject aims to evaluate whether formulation of a new tobacco resistant powder met material& new proposed method of production would provide tooling with advanced wear propertieswhilst enabling reduced overall manufacturing costs.
