Paper Abstract

Experiments have been performed to measure cutting forces for slow speed turning of aluminum 2024-T361 with diamond tools. A measurement apparatus. was designed and incorporated into an existing precision lathe. Both specimen preparation and cutting force measurements were performed with the lathe. Cuts of 12 mm (0.5 in) in length were made and average forces obtained for a variety of cutting depths, speeds, rake angles, and lubricants. The results of this work show that (a)cutting force and area are linearly proportional to each other, (b)cutting force increases but surface finish improves as the rake angle is varied from 5 to -15 degrees, and (c)cutting force decreases with improved surface finish at higher speeds if a lubricant is used. Finally, agreement between these results and those of a numerical analysis has been achieved.
