FORM ACCURACY AND CUTTING FORCES IN TURNING OF X5CRNI18-10 SHAFTS: A STUDY ON CYLINDRICITY, COAXIALITY, STRAIGHTNESS, AND WAVINESS AT SMALL FEEDS

This paper investigates how the cutting speed (vc), feed rate (f) and depth of cut affects the cutting forces and the quality of the surface during turning operations. For the study different experiments have been performed at two depths of cut (0.5 mm and 1.0 mm) to observe how they affect the cutting force, cylindricity, coaxiality (COAX DIN), straightness and waviness. From the results it can be said that the cutting forces and surface deviations increase with the increase in depth of cut. Cutting force normally brings down the forces and enhances surface quality but feed rate has exactly opposite impact. Thus, it is necessary to choose parameters wisely to keep machining efficiency and dimensional accuracy in balance.
