Bearing Surface Area of Plate Macrorelief and Ways of Increasing It in the Course of Grinding Parts Made of Corrosion-Resistant Steel by Means of Aerobor Grinding Wheels

Аннотация

Monitoring of the operation of grinding of the end faces of parts used in the petrochemical industrial by means of digital photography and topograms of the end faces with the use of a comparatively simple method is proposed. A new numerical quality indicator that describes the relief of macro-irregularities is introduced for this purpose. The technique has been approved for grinding of corrosion-resistant steels by Aerobor wheels. Reasons for the occurrence of a pseudo-regular relief on a surface are established. A relationship between the kinematics of grinding and the variation in the bearing surface area is demonstrated by means of statistical analysis. Recommended fields of effective application of the results of the study are given.
