A turning machining experiment was performed at the UCSI University's Mechanical Engineering workshop using a lathe machine with palm oil as lubricant. It was observed that during the entire machining, the technician set cutting tool perpendicular to the direction of tool motion. A further investigation revealed that the tool rake angle was 25° while the dynamometer results' analysis showed that the frictional force and the normal force to the friction was 5 kN and 25 kN respectively. Analyze how the chip thickness will be affected if the machining is performed without any lubricant and the frictional force is increased by 100 %. Assume that, all other parameters were kept constant during the entire operation for both machining with lubricant and the dry machining process.
