Ductile iron austempered castings are characterized by high resistance to fatigue, impacts, high strength and wear resistance than other steels ductile castings. For these reasons, this material is considered by the designers at the design stage or redesign parts to reduce the weight of industrial components and satisfy the most demanding mechanical requirements. The mechanical properties of ADI are achieved after performing a heat treatment to produce an ausferrite microstructure. However, this microstructure significantly affects the machinability of the material and a precise control of the interactions between microstructure, chip formation or tool wear is essential to optimize the cutting process. In this paper, the use of ceramics for dry machining of castings ADI tools is proposed. Different types of technical ceramics available in the market have been analysed and compared identifying the dominant wear mechanisms to choose the most suitable ones for dry machining. A fast method has been employed to choose the most appropriate tool by using the wear rate magnitude. This was determined indirectly after signal recording by analysing the variation of the cutting forces against the machining time. AS well, different tests have been done scanning the cutting parameters in order to identify their influence on wear.
