Abrasive belt grinding force and its influence on surface integrity

ABSTRACT

Titanium alloys have been widely used in ships, aviation, aerospace, and other industries because of their excellent material properties. In the abrasive belt grinding of titanium alloy materials, abrasive belt grinding is a kind of flexible grinding, and its cutting force and material removal are important parameters that characterize the machining process. Powerful belt grinding can realize the removal of large materials, but ensuring its surface integrity is also crucial to the comprehensive material properties of titanium alloy materials. This paper studies the grinding amount: the effect of feed rate, linear speed, and initial grinding pressure on the grinding force, and the influence of the grinding force on the law of material removal and surface integrity. By studying the relevant parameters of abrasive belt grinding consumption, revealing its changing law, determining the best grinding range, and obtaining the best powerful grinding parameters. It is concluded that the maximum grinding force can be achieved when the maximum initial grinding pressure is 12N and the smaller feed speed is 200 mm/min and the medium-high line speed is 15.6 m/s while achieving a large margin of material removal and ensuring better surface integrity.
