Özet:

In this review study, it is aimed to determine the gains and deficiencies obtained by making a detailed analysis of the unconventional manufacturing methods used in the machining of ceramics. The most used of these methods can be listed as abrasive jet machining and abrasive water jet machining, ultrasonic machining and rotary ultrasonic machining, electro erosion and wire erosion machining. Machining with abrasive jet and abrasive water jet is preferred with some superior features. Some of these features are that it generates very little heat in the cutting zone, can be cut and machined of all kinds of materials such as metal, non-metal, composite, ceramic, a higher material removal rate than wire erosion machining and better surface integrity than laser machining. With the ultrasonic and rotary ultrasonic processing method, it is superior to other methods, especially with the precision processing of hard and brittle materials. The reasons for choosing the electrical discharge machining and wire electrical discharge machining can be listed as the fact that every piece that conducts electricity can be processed, very complex shapes can be formed, physical deformation is less and the area affected by heat treatment is less since there is no contact between the tool and the workpiece. In future research, focusing on multi-purpose optimization studies including metal removal rate, surface quality and energy consumption and machining costs will make significant contributions to high productivity and sustainability.
