Abstract


The process of introducing high-strength cast iron with nodular graphite, which have a wide range of performance properties, is restrained by a low level of machinability by cutting. Results of research on cutting force and thermo-e.m.p. showed their dependence on the characteristics of the structure of cast irons and a qualitative agreement with the evaluation of machinability in resistance. The characteristics of the cutting process can be recommended as non-direct methods of evaluating machinability. However, the final conclusion about machinability and recommendations for the selection of optimum cutting regimes in specific production conditions can only be made after full-fledged studies, including rigorous tests.


Keywords
