Application of spectroscopic (Fourier's) analysis for the evaluation of rock cutting processes Author: J. Jonak
The present is an attempt to apply the Fourier's single tome series analysis for the evaluation of rock cutting processes with separated cutting wedges of specific geometry. It has been assumed that the time series here is run of cuting force values (F sub c) in time period (t) obtained in the rock cutting process with a cutting wedge. For the analysis it was suggested the use of FFT and especially spectroscopic density in the function of period. The time series was treated as a time series, with specific characteristic for the tool's geometry, cyclic rock loosening process. Experimental researches and results of time series for Rapid 83, NKP2w and AM-50/96 (stopni) tools confirm cutting cycles appearance for each type of these tools. It was noticed that cycle quanitity depends on both: cut rock, strenght parameters and geometry of the tool. Settlement of closer correlations requires further investigations.
