Measurements of Surface Texture Parameters After Ultrasonic Assisted and Conventional Grinding of ZrO2 Based Ceramic Material Characterized by Different States of Sintering

The article presents the results of measurements of surface texture parameters after ultrasonic assisted grinding (UAG) and conventional grinding (CG) of ZrO2 based ceramic material. The machined samples are characterized by different states of sintering. Ultrasonic 20 linear machine tool and two different diamond grinding pins were applied to machine ceramic samples. Surface roughness measurements were performed and the values of parameters were computed using Infinite Focus Real 3D microscope (optical focus-variation technique) and 3D scanner Talyscan (contact measurement). The results of measurements were analyzed in order to state the influence of machining conditions on surface texture parameters.
