Experimental Research on the Mathematical Model of Abrasion Ratio Based on the Abrasive Belt Grinding

Abstract

Abrasion ratio is an important parameter to estimate the wear resistance of abrasive belt grinding, reacting the relationship between the material removal and the abrasive belt wear, and also, its value is an important basis to instruct the process of abrasive belt grinding. The mathematical model of material removal is obtained by analyzing the basic mechanism theory of centerless cylindrical grinding in this paper, and the impact curve which react the relationship between the abrasion ration and the material removal or cutting depth is obtained by using the software of Mathematica. The abrasion ratio is testified in this paper by the experiment test of abrasive belt grinding for the titanium alloy, 45# steel and 304# stainless steel, systematic analyzing the affection of abrasion ratio on the hardness ratio and the belt speed. Experimental result shows that: belt speed is superior than hardness ratio to the abrasion ratio, and the mathematical model of material removal is testified by this experimental research. So the mathematical model of material removal could be used with theoretical basis in belt grinding process.
