METHOD OF PROCESSED MATERIAL HARDNESS DETERMINING IN MACHINED PART CONTACT ZONE WITH TOOL DURING CUTTING Russian patent published in 2016 - IPC B23B25/06 B23Q17/20 

FIELD: metal processing.

SUBSTANCE: invention relates to metals machining and can be used for processed material hardness determining at different cutting modes in specific conditions on selected processing equipment to assess cutting modes selection correctness or their correction during processing. Method involves preliminary processing of part at cutting speeds V₀ and V₁, when recording corresponding values of machine high-frequency oscillations effective amplitudes A₀ and A₁. After which performing part processing with current cutting speed V_t while measuring machine high-frequency oscillations effective amplitude current value of A_t, and material hardness value HB_t in part contact with tool zone is determined by formula , where HB₀ is material hardness value in initial state before processing, A_p is machine high-frequency oscillations amplitude calculated value, which is determined by formula A_p=A₀+(V_T-V₀)×(A₁-A₀)×(V₁-V₀)^-1.

EFFECT: expanded performances of processed part material hardness determining process.
