    Abstract
  • The wear condition of diamond tools determines its service life. The 6061-T6 magnesium-aluminum alloy workpiece was cutted with diamond PCD tool. Through the changes of cutting forces and cutting temperatures at different cutting speeds, cutting depths, vibration frequencies and tool back angles, the workpiece surface roughnesses and tool wear areas at different tool back and forth angles, feed values and speeds of revolution were studied. The results show that the cutting forces and the cutting temperatures increase with the increase of cutting speeds and cutting depths, and decrease with the increase of vibration frequencies. With the increase of the tool back angles, the cutting forces of diamond tool decrease first and then increase slowly, but it has little effect on the cutting temperatures. When the rake angle of the tool is 10°, the back angle of the tool is 8°, the cutting speed is 0.46 m/s, the cutting depth is 28 μm, the feed value is 0.10 mm/r, the speed of revolution is 4 100 r/min, the vibration frequency is 22 kHz and the cutting amplitude is 9 μm, the diamond tool has the smallest wear area, the lowest degree of wear and the longest service life, but the surface roughness of the workpiece is slightly higher.
