EFFECT OF CUTTING SPEED ON GENERATION OF HEAT AT WORK-TOOL INTERFACE OF COPPER BASED SILVER AND BRASS ALLOYS

Copper and its alloys are extensively used in various electrical and other industrial applications, due to its high thermal and electrical conductivity. The machinability of copper depends on its alloying elements and its composition. The addition of alloying elements reduces machinability and hence the amounts of heat generated also variable which is dependent on the composition of the alloying element and the machining parameters. The current research is an attempt to study the amount of heat generated at the work tool interface for varying cutting speeds and varying compositions of brass and silver in copper. The research reveals that the number of heat generated decreases as the amount of silver content increases in the alloy indicating higher thermal conductivity.
