چکیده مقاله
In this paper by measuring the cutting forces the effect of the tool shape and qualifications sharp and worn cutting tools of both vee and knife edge profile and cutting conditions depth of cut and cutting speed in the turning operation on the tool deflection and cutting force is investigated The workpiece material was mild steel and the cutting tool was made of high speed steel Cutting forces were measured by a dynamometer type P E I serial No 154 The dynamometer essentially consisted of acantilever structure which held the cutting tool Deflection of the cantilever was measured by an L V D T Mercer 122 deflection indicator No cutting fluid was used during the turning operations A modern CNC lathe machine Okuma LH35 N was used for the tests It was noted that worn vee profile tools tended to produce a greater increase in the vertical force component than the axial component, whereas knife tools tended to show a more pronounced increase in the axial component
