Abstract
The effect of cutting speed, tool rake angle, and wearland length on the nature of the surface generated in machining annealed red brass under unlubricated and lubricated conditions is studied. The machined surfaces are examined using optical and scanning electron microscopy. The machined surfaces were observed to have defects such as microcracks and macrocracks perpendicular to the direction of relative work-tool motion, cavities and plastically deformed regions. The surface damage decreases with an increase in the cutting speed and/or the positive tool rake angle. The presence of lubricant in the cutting region results in a surface of high quality.
