Abstract

Tool steels are widely used in the plastics transformation industry, mainly as raw material to produce molds and dies. In this work, the influence of feed and rounding of the cutting tool edge in the machining of VP20TS steel will be investigated. For this, the wear of the cutting tool will be analyzed with the aid of optical microscopy, scanning electron microscopy, and energy-dispersive x-ray spectroscopy, the roughness of the machined surface will be evaluated through the parameter Ra, and the electric current required by the machine tool will be monitored by means of Hall effect sensors attached to the main power cables. The results obtained showed that the cutting tool wear was attenuated with the use of rβ = 0.03 mm, with adhesion being the predominant wear mechanism. The increase in feed influenced the decrease in wear. The machined surface roughness decreased when the tool with the highest cutting-edge radius value was used. Low-cost system used to monitor the electrical current required by the machine was sensitive to changes in feed and cutting-edge preparation. For higher values of feed and cutting-edge radius, higher values of electric current were required, indicating that edges prepared with larger values of radius generate greater cutting forces.
