Green Ceramic Machining: Determination of the Recommended Feed Rate for Y-TZP Milling

Manufacturing of advanced ceramic parts exhibiting complex geometries is laborious and expensive. Traditionally, the machining carried out on a so-called ‘green ceramic’: compact composed powder held with help binder. This difficulty due not only to composition material, but also lack methods that determine optimal parameters. The goal this paper apply method based ductile material behavior feed rate working range ensure quality. Indeed, previous study demonstrated limits in determining cutting speed. In case, two removal mechanisms are observed: mechanism dominated by pulling proper mechanism. demonstrates specific energy reliable indicator for quality assessment. studied recommended parameters Y-TZP green 3 mm diameter cylindrical tool are: speed 250 m/min, per tooth 0.037 mm/tooth, an axial depth cut 0.7 mm, radial mm.
