Investigation of the Effect of Axial Cutting Force on Circular Diamond Sawblade Used in Marble Cutting Process

Abstract

Abstract In the marble cutting process, generally, normal and tangential forces are taken into account. However, the axial forces (F z ) on the cutting disc affect the economic life of the disc and segment wear significantly. In this study, the effect of the axial forces on discs, which are used in the marble cutting process, on cutting performance was investigated. Therefore, by taking into account different cutting parameters (peripheral speed, traverse speed and depth of cut), the axial forces on circular saw were measured by means of a dynamometer. In addition to this, using a laser displacement meter, the amount of axial deviation for each cutting parameter in the course of cutting was determined. According to the experimental results obtained, the increase of traverse speed and depth of cut also significantly increases the axial deviation of the cutting disc. Moreover, it is observed that traverse speed and depth of cut have an impact on axial deviation of the saw at the initial moment when the saw starts to cut.
