Influence of Cutting Speed to Vibrations and Roughness of Machined Surface during Turning

This paper deals with influence of cutting parameters to vibration during turning of steel on metal lathe. We observed the effect of changing cutting speed to machine vibration and the quality of the machined surface. Cutting parameters was changed in five steps. We used piezoelectric accelerometer MMF KS78.100 to sense vibrations, data acquisition unit Adlink USB 2405 was used for recording and processing signals from accelerometers. Recorded signals were transformed by Fast Fourier Transform from time domain to frequency domain. Software Visual Signal DAQ Express was used to perform this transformation.
