Abstract


    WE STUDY THE MILLING PROCESS OF INCONEL. BY CONTINUOUS INCREASING THE CUTTING
DEPTH WE FOLLOW THE SYSTEM RESPONSE AND APPEARANCE OF OSCILLATIONS OF LARGER AMPLITUDE. THE CUTTING FORCE AMPLITUDE AND FREQUENCY ANALYSIS HAS BEEN DONE BY MEANS
OF WAVELETS AND HILBERT-HUANG TRANSFORM. WE REPORT THAT IN OUR SYSTEM THE FORCE
OSCILLATIONS ARE CLOSELY RELATED TO THE ROTATIONAL MOTION OF TOOL AND ADVOCATE FOR
A REGENERATIVE MECHANISM OF CHATTER VIBRATIONS. TO IDENTIFY VIBRATIONS AMPLITUDES
OCCURRENCE IN TIME SCALE WE APPLIED WAVELET AND HILBERT-HUANG TRANSFORMS.
