Surface Features in Honing Zirconia Ceramics Using Fine Grains with Ultrasonic Assistance

Abstract:

Experiments on surface features were carried out in honing zirconia engineering ceramics using fine grains. In ultrasonic honing, the surface fracture ratio increased quickly when the depth of cut is more than 3 μm, while in common honing it performed an ascending trend from depth of cut 1.5 μm. The value of surface roughness in ultrasonic honing increased along with the depth of cut; while it descends contrast to the depth of cut when the honing velocity is less than 0.58 m/s in traditional honing. As for honing velocity over 0.74 m/s, it deceased firstly to the minimal value for depth of cut 1μm, then began to ascend along with depth of cut. The value of surface roughness descended to minimum value for the range of honing velocity 0.41-0.58 m/s in traditional honing, while the optimized honing velocity ranged 0.58-0.75 m/s in ultrasonic machining. The surface roughness in ultrasonic honing was superior to that in traditional honing.
