Tribological Behaviours of Wax-in-Oil Gel Deposition in Orthogonal Cleaning Process

Abstract

Tribological behaviour of wax-in-oil gel deposition at orthogonal cleaning process has been directly observed with a custom-built experimental setup. Experimental results show that the chip formation of wax scraping is due to rubber tribology of elastomer disc. The scraping chip instability arises from a competition between scraping forces and the adhesion forces. An analysis of debris-material removal rate in wax scraping with negative rake face has been carried out. The study has also shown that the wax-scraping force component is sensitive to rake angle, which may be used as primary basis for developing wax-removal estimating strategies. Flank face wear results in a substantial increase in the wax-scraping force, which should be incorporated into the wax-cleaning efficiency predictive model. The behaviours of the residual phenomenon depend on the inlet aggregation in orthogonal wax-cleaning process.
