Abstract

This study examines how change in the direction of the crystal structure of lithium niobate and change in rake angle affects surface roughness. Since crystallographic orientation of anisotropic material differs according to cutting direction, the integrity of the finished surface will also differ. We performed an experiment assuming that a cutting direction conducive to a good finished surface could be obtained by matching the angle formed between the rake plane and slip plane with conditions that suit a good surface. We found that the rake angle and slip plane are factors affecting the roughness of the finished surface. It was also found that changing the rake angle to bring the angle formed between the slip plane and rake plane (crossing angle) near 30 and -25° tends to reduce the roughness of the bottom surface and the amount of cracks.
