Temperature distribution in the machining zone during precise turning of NiTi alloy

摘要

Temperature is one of the most important factors in the machining process. This is even more important for modern non-ferrous alloys. The subject of the study is the temperature both in the area of the machined surface as well as in the machining zone obtained during the precise rotation of a shaft made of a NiTi shape memory alloy. The temperature was tested in laboratory conditions and recorded using the FLIR 620 thermographic camera. ThermaCam Researcher software was used to archive and analyze the obtained results. The tests were conducted for two independent parameters (v_c, f) affecting the temperature in the machining zone. The configuration of parameters was determined using he orthogonal plan L9, with two control factors, changing at three levels, developed by G. Taguchi. The ratio S / N and Anova were made to determine the best cutting parameters affecting the temperature.
