Investigation of ductile/brittle chip formation zone in the context of manufactured geometry with different CAM paths strategies

For maintenance conform processing of brittle materials (ceramics, glass), the resulting chips are not continuous, as in case soft and tough materials, it is called a chip removal range. In this machining zone, quality produced surface may decline (appears cracks pitting material) tool life also decreases. When defining cutting technology (technological parameters, edges, cooling / lubrication, etc.), must be carried out ductile However, due to wear, range cross transition then can work formation zone. paper, machinability zirconia oxid ceramics has been investigated. The aim research find correlation between wear tool, volume change manufactured pockets transitions ranges measured by deformations on edge machined material. It was observed that they overlap large extent, consequently, these phenomena easily applied for monitoring realising condition-based maintenance, main scientific contribution paper.
