In this article the authors propose a new approach to information and metrological support and assessment of technical condition of metal-cutting machines, based on a phase-chronometric method. A phase-chronometric information measuring system for the UT16P machine was created. The authors carried out studies of operation of the UT16P machine by measuring kinematic parameters of rotation of a spindle with application of the phase-chronometric method. Results of measurements during processing of a cylindrical work piece made of steel ShH15 with a firm alloy T15K6 are presented. The authors obtained steady diagnostic signs in the form of ranges of spindle’s natural oscillation frequency.
