document: Marble cutting with single point cutting tool and diamond segments An investigation has been undertaken into the frame sawing with diamond blades . The kinematic behaviour of the frame sawing process is discussed . Under different cutting conditions , cutting and indenting-cutting tests are carried out by single point cutting tools and single diamond segments . The results indicate that the depth of cut per diamond grit increases as the blades move forward . Only a few grits per segment can remove the material in the cutting process . When the direction of the stroke changes , the cutting forces do not decrease to zero because of the residual plastic deformation beneath the diamond grits . The plastic deformation and fracture chipping of material are the dominant removal processes , which can be explained by the fracture theory of brittle material indentation
