Abstract: To study the sawing technology of diamond wire saw cutting carbon fiber composite, the experiments of cutting the carbon fiber composite materials on a diamond wire saw cutting machine tool were performed. The results show that the joint-cutting path of carbon fiber composite material is more perfect under the conditions of lower feed speed and higher wire saw linear speed; the stability of diamond wire saw is higher under the conditions of lower linear speed and higher tension of diamond wire saw; the tangential sawing force decreases with the increase in wire saw linear speed；the normal sawing force increases with the increase in wire saw feed speed; the uneven distribution of diamond abrasive grains , the different thicknesses and clamping positions of the work pieces and the wire saw cutting direction result in the joint-cutting path of carbon fiber composite material being not an ideal straight line.

Key words: manufaturing technology and equipment, electroplated diamond wire saw, carbon fiber composite material, machining path
