Aِ studing The Effect of Chemical Composition of Workpiece on Built Up Edge Formation And Surface Roughness
Engineering and Technology Journal,

Abstractthe phenomena built-up edge was the unwanted rough edge on cutting tool that is created by workpiece material welding onto the tool during cutting , occurs at the chip/tool interface when multiple materials are machined at low cutting speeds under high compressive stresses, this study involve relation between the chemical composition of workpiece and the built-up edge ( B.U.E ) formation which is generated on cutting tool during machining at dfferent types of low carbon steel
using turning machine , experments prove that increasing percentage of carbon on workpiece causes reduction in weight of cutting tool from ( 14.532g to 13.823g ) at cutting speed 40 m/min and 0.10% and 014% carbon also to 12.672g at 0.20% carbon because built – up edge was disappear and surface roughness was improving from the value ( 5.43μm ) at 0.10% carbon and to ( 3.362 μm ) at 0.14% carbon and to (3.543μm) at 0.20% carbon .
