An investigation was carried out to study the cutting forces in the deep sawing of hard granite. The maximum depth of cut was up to 120mm in the investigation. During the deep sawing of granite, the cutting power, vertical and horizontal forces were measured respectively by wattmeter and dynamometer. The tangential and normal force components acted on the saw-blade and each diamond grit were then calculated and analyzed according to the measurements. The distribution of stress in the saw-blade was also analyzed by Finite Element Method (FEM). It is hoped that this study will be of benefit to wider applications of deep sawing.
