| ABSTRACT This paper is concerned with investigating the effects of cutting conditions on sensor signals, employing tool inserts with chip breaker geometry and a harder workpiece material. Medium double coated carbide grade tool inserts with integral groove chipbreaker was used to cut EN24T alloy steel. The focus was to investigate and corroborate the effects of cutting conditions (cutting speed, feed rate and dept of cut) on the cutting forces and vibrations signals during orthogonal turning using coated chip-breaker geometry indexable tool inserts. Cutting forces and vibration signals were recorded on-line at the various cutting conditions, and these analysed in time and frequency modes for features that were sensitive to the variation in the cutting conditions. Peculiar characteristics in the signal spectrum were identified and these were easily associated with changes in the cutting conditions as well as chip lamination. | ||||
