Marksa, Novosibirsk, 630073, Russian Federation Abstract A technique for measuring drive power losses of the main turning lathe motion and the calculation of its efficiency are considered. In addition, analog-to-digital converters equipped with a set of sensors to measure the necessary parameters to be then transmitted to a computer is proposed instead of pointer-type instruments usually used in laboratory facilities. This will improve the accuracy and reliability of measurements as well as significantly reduce the complexity of data processing.
