| Abstract |
Compared to other machining processes, conventional grinding has a low material
removal rate and involves high specific energy. A major part of the specific energy in grinding is
changed to heat which makes harmful effect on surface quality. A recent and promising method is
the use of ultrasonic assistance to increase the material removal rate along with decreasing the
thermal damage on the workpiece and reducing cutting forces. The advantages of Ultrasonic
Assisted Grinding (UAG) were proved mostly for the brittle material. Our investigations show the
improvement on the surface roughness, reduction of the grinding forces and thermal damage in case
of using UAG comparing to Conventional Grinding (CG) for a soft material of 100Cr6. The
designed and developed ultrasonically vibrated workpiece holder and the experimental investigation
show a decrease of up to 40% of normal grinding forces. |
