Automatic Measurement of Rotational Speeds and Lathe Maintenance

This paper presents a procedure for measuring the rotation velocity of rotating parts. Theoretical introduction defines significant terms such as rotation velocity measurement, angular velocity, angular velocity measurement units and velocity detectors. This paper also reveals a short view on mechanical and electrical tachometers, sensor technology used in tachometers, contact, optic sensors and magnetic sensors. A short view is presented in Lab View user interface created in the laboratory of the Technical Faculty in Rijeka that has been used with stroboscope PCE-OM 15 and with digital tachometer PCE 155. The results are discussed and recommendations given for proper speed measurements and its influences on controlled lathe machine.
