Abstract
Grinding performance of grinding wheel dressed with a diamond rotary dresser is experimentally investigated under various dressing conditions, analyzing size generation process, grinding force, surface finish, wheel wear and so on. Main results obtained in this paper are as follows: (1) Variation process of dressing force in rotary dressing is similar to that of grinding force in a plunge grinding cycle. (2) Wide variety of grinding performance can easily be obtained by changing dressing conditions such as infeed rate of dresser, speed ratio of dresser to wheel and relative dressing speed. (3) The integer revolution ratio of wheel to dresser should not be selected. (4) The grinding performance of wheel dressed with this technique can be kept constant longer than in any other methods, because of the remarkably less wear of rotary dresser.
