- Nowadays acoustic emission (AE) method is used in many fields of science, including in the diagnosis of machining processes such as turning, grinding, milling, etc. Determining of turning parameters has a great impact on the quality of the surface. This is especially important during finishing treatment. In the study of acoustic emission, method was used to optimize the cutting depth. Optimization was to determine the depth of cut, at which the vibration level exceeds the set level. The research was carried out on a universal CDS 6250 BX-1000 lathe centre using dynamometer DKM 2010 where assembled removable insert CCMT 09 T304 PF. Lathing process was performed on the shaft of 40 mm in diameter made of S235JR steel. The research was carried out at constant cutting speed v = 145 m/min and at constant feed f = 0.114 mm/rev. In the research was used a set of acoustic emission Vallen System. The kit includes: 4 channel signal recorder AMSY 6, two measurement modules ASIP-2/S, preamplifier with a frequency range 20 kHz – 1 MHz and the strengthening of 34 dB and AE signal measurement sensor type VS 150M, with a frequency range 100 – 450 kHz. During the study, the acoustic emission (AE) generated during the lathing process was recorded parameters: amplitude, number of events – hits, the effective value of the signal (RMS). Analysis of the research results allowed to determine the maximum depth of cut, at which the vibration does not reach the set limit value. The study can be the basis for the use of acoustic emission method to determine the parameters of the finishing lathing for obtaining a high quality surface.
