Thermo-physical aspects of chip machining
Zuzana Murčinková and Karol Vasilko
The paper deals with thermo-physical aspects of chip machining, namely with the cutting speed effect on heat flow in cutting zone and it opens discussion about chip formation involving size of temperature influence. The developed numerical models allow to realizing the numerical experiments and confirming statements given in literature. Due to complexity of non-linear processes in cutting zone the experimental tests were realized. The results of experimental measuring are basis for concept of low energy chip machining in terms of high productivity machining. The presented experiments focus on the cutting speed effect on heat flow and plastic deformation angle in cutting zone and the temperature effect on cutting resistance. The outcomes of paper are confirmed by numerical experiments and experimental measuring tests.
