RAY METHOD OF MEASURING THE DIMENSIONS OF MACHINE PARTS SURFACE IRREGULARITIES
Annotation
A method is proposed for measuring irregularities on the surface both during manufacturing (e.g., roughness) and during testing and operation of parts (e.g., contact fatigue, corrosion, cavitation, impact and other damage). It is proposed to solve this problem using a conventional digital microscope equipped with one light source, the beam of which coincides with the optical axis at its inclined position. Algorithms for analyzing characteristic images of irregularities and methods for their assessment using the ImageJ tool are developed. Algorithms for calculating the depth/height of irregularities based on images obtained at an inclined position of the optical axis are substantiated. Examples of roughness and damage assessment are demonstrated.
