Application of the three-dimensional scanning system to evaluation of the abrasive tool wear

Abstract

Zużycie narzędzia ściernego jest podstawowym kryterium oceny szlifowalności materiału obrabianego, które ma w konsekwencji decydujący wpływ na okres trwałości narzędzi ściernych. W pracy dokonano oceny zużycia narzędzi ściernych z zastosowaniem skanowania laserowego. Zastosowana metoda skanowania laserowego umożliwiła wyznaczenie cech stereometrycznych narzędzi ściernych. Przedstawiono przykłady zastosowania opracowanej metody do oceny zużycia narzędzi ściernych w procesach szlifowania.Grinding is one of the basic precise machining methods. Abrasive and shape wear, as well as smearing of the tool active surface handicap the processing results. The loss of cutting capacity in abrasive tools or alteration of their shape influences the surface quality and precision of the workpiece dimensions and its shape. Evaluation of the abrasive tool surface is the basic criterion of forecasting the tool durability and the process results. The applied method of laser scanning enabled determination of the surface coordinates and subsequently of its stereometric features. Using the information on the abrasive tool surface stereometric structure, evaluation of the level of changes in stereometric features of the tool during the machining process is presented. The developed method allowed for evaluation of the level of abrasive tool wear and, subsequently, formed foundations for assessment of the influence of machining parameters on the durability of abrasive tools, evaluation of the influence of the parameters of the process of shaping the abrasive tool active surfaces on their stereometric characteristics and evaluation of the level of correlation between the monitored process parameters and the degree of the abrasive tool wear
