Multi-set-gear-shaped diamond saw blade self-formed by orderly positioning and weakening of carcasses and manufacturing process of saw blade

The invention discloses a multi-set-gear-shaped diamond saw blade self-formed by orderly positioning and weakening of carcasses and a manufacturing process of the saw blade. The saw blade is composedof segments and a base body, and the segments are formed by compounding working layer sheets and middle separation layer sheets, wherein the thicknesses of the working layer sheets and the middle separation layer sheets are 0.2-2.0 mm. Segment working layers are made of metal powder and diamond, separation layers are made of graphite powder, ceramic powder and copper-tin alloy powder, organic solvents are added to the working layers and the separation layers, and the working layers and the separation layers are manufactured into working layer sheet blanks and middle separation layer sheet blanks separately; weakened carcass particles are embedded in predetermined positions with pit structures of the working layer sheet blanks, and then the working layer sheets and the middle separation layer sheets are alternately
