“…To effectively machine ceramic materials, many conventional and unconventional methods have been tried over the past decades [123,124]. Many studies on zirconia, alumina, silicon nitride and optical ceramics showed that an ultra-precision machining operation without brittle fractures could be obtained by applying ultrasonic vibration on cutting tools [1,24,109,125,126].…”

Ultrasonic vibration-assisted (UVA) machining is a process which makes use of a micro-scale high frequency vibration applied to a cutting tool to improve the material removal effectiveness. Its principle is to make the tool-workpiece interaction a microscopically non-monotonic process to facilitate chip separation and to reduce machining forces. It can also reduce the deformation zone in a workpiece under machining, thereby improving the surface integrity of a component machined. There are several types of UVA machining processes, differentiated by the directions of the vibrations introduced relative to the cutting direction. Applications of UVA machining to a wide range of workpiece materials have shown that the process can considerably improve machining performance. This paper aims to provide a comprehensive discussion and review about some key aspects of UVA machining such as cutting kinematics and dynamics, effect of workpiece materials and wear of cutting tools, involving a wide range of workpiece materials including metal alloys, ceramics, amorphous and composite materials. Some aspects for further investigation are also outlined at the end.

Knowing cutting force in rotary ultrasonic machining (RUM) can help optimizing input variables. RUM of brittle materials has been investigated both experimentally and theoretically. However, there are no reports on cutting force models for RUM of brittle materials. This paper presents a mechanistic model for cutting force in RUM of brittle materials. Assuming that brittle fracture is the primary mechanism of material removal in RUM of brittle materials, the cutting force model is developed step by step. On the basis of this mechanistic model, relationships between cutting force and input variables (such as spindle speed, feed rate, ultrasonic vibration amplitude, abrasive size, and abrasive concentration) are predicted.

“…These electrically conductive reinforcements not only improve the hardness [29] but also reduce the electrical resistivity, rendering the ZrO 2 composites feasible for electrical discharge machining (EDM) [30] and, thus, overcoming technical difficulties and avoiding high cost associated with grinding of normally difficult-to-machine hard materials. EDM is one of the most important noncontact machining methods for hard and brittle materials, particularly for applications where dimensional accuracy combined with complex geometries are required [31]. Unlike traditional cutting and grinding processes which rely on a much harder tool or abrasive material to remove the softer work material, the EDM technology utilizes a series of discrete electrical sparks to erode the superfluous work material and to generate the desired shape.…”

Impact of Wire-EDM on Tribological Characteristics of ZrO2-based Composites in Dry Sliding Contact with WC–Co-Cemented Carbide

The effect of surface conditions and secondary phase addition on the dry sliding friction and wear characteristics of five yttria-stabilized ZrO 2 -based composites with 40 vol% WC, TiCN or TiN was investigated using an ASTM G133 pin-on-flat sliding contact configuration. WC-6wt%Co-cemented carbide pins were used as mating material. The friction and wear level were higher for wireEDMed ZrO 2 -based composites compared to their equivalent ground specimens. This finding could be correlated to flexural strength measurements, revealing strong discrepancy between wire-EDMed and ground surfaces. The most favorable tribological characteristics were encountered with ZrO 2 -WC composites compared to ZrO 2 -TiCN and ZrO 2 -TiN grades.
