STUDY OF MACHINING OF THERMAL RECTIFICATED Corymbia citriodora AND Pinus elliottii
MetadataShow full item record
This study evaluated the influence of thermal rectification in machining Corymbia citriodora and Pinus elliottii. The heat treatment was carried out for 6 hours at temperatures of 100 degrees C, 140 degrees C, 160 degrees C, 180 degrees C and 200 degrees C and evaluated the performance of machining in three different material cutting tools, polished and hard metal carbide with TiB2 coating. The cutting power and roughness R-a and R-t of the machined surfaces with three different tools were evaluated. The power has proven lower for Pinus elliottii species. The roughness was lower for Corymbia citriodora wood. The roughness R-a and R-t were lower for heat treatment temperature of 180 degrees C.
