Abstract

In this ihesis discusses about the comparative quality cutling tools and the workpiece surface roughness. The testing melhods which were applied in this sludy is Hardness testing performed on the workpiece of aluminum and low carbon Steel using a Vickers test equipment. Testing continued on the workpiece surface roughness after lurning with the same feed motion, and depth of cut and spindle rotation variations, which uses cutting tools HSS and cutting tools of leaf springs used car HINO FM260 which diheat treatment (spherodizing, lempering 300°C, lempering 550°C) and non- heat treatment. The testing melhods which were applied hardness testing and workpiece surface roughness testing. Hardness results obtained for low carbon Steel 152.661 VHN, aluminum B of99.442 VHN and aluminum A 81.441 for VHN. fVhile the surface roughness testing performed on the workpiece with the smallest surface roughness values are details as follows: Aluminum A, in rotation spindle 300 rpm with Ra 2.250 pm is cutting tool Temper 300 ° C, in rotation spindle 600 rpm with Ra 1.923 pm is cutting tool HSS, and the in rotation spindle 1100 rpm with Ra is 1,190 pm cutting tool HSS. Aluminum B, in rotation spindle 300 rpm with Ra 4,050 pm is cutting tool Temper 300 ° C, in rotation spindle 600 rpm with Ra 3,353 pm is cutting tool non heat treatment, and the in rotation spindle 1100 rpm with Ra is 2.697 pm cutling tool HSS. Low carbon Steel, in rotation spindle 300 rpm with Ra 5,833 pm is cutting tool Temper 550 ° C, in rotation spindle 600 rpm with Ra 5,570 pm is cutting tool non heat treatment, and the in rotation spindle 1100 rpm with Ra is 5.077 p m cutting tool non heat treatment.
