Prediction Of The Influence Of Cutting Conditions On Surface Morphology After Its Thermal Spraying With Stellite 6 Alloy

Abstract The presented paper is devoted to the basic influences of the cutting conditions on the basic parameters of the roughness of the surface machined by longitudinal turning; the investigated surface was before the machining modified by the technology of thermal spraying. High-speed Oxy-Fuel (HVOF) thermal sprays, in particular, Stellite 6 sprays based on Cobalt and Chromium alloy, are widely used in the industry thanks to their excellent mechanical properties, wear resistance, corrosion resistance and good temperature stability in comparison with steel for example. From experimental results in the specified range of cutting speeds, feeds and cutting depths, new predictive models of roughness parameters were compiled using mathematical and statistical methods, followed by application of neural networks in order to confirm the obtained conclusions. Research results have proved that feed turning technology is a suitable technology for machining coatings generated by Stellite 6 alloy thermal sprays in such user cases where additional surface treatment is required for specific reasons.
