Abstract. An effective artificial base method for measuring machine part wear in field conditions with the use of digital microscopes and various means for notch formation is considered. Methods of notch formation and evaluation of their parameters are described in details. A method of wear assessment with the use of Digmicroprof microscope is developed. Calculation of the notch depth and residual service life expectancy is carried out with the use of specially designed programs in MathCad for all variants of the notch type.
Keywords: digital microscope, wear, notch, measurement
