Chip Formation Model of Cutting Fiber-Reinforced Plastics
· The present paper studies the chip formation and constructs an original model for the case of cutting perpendicular to the unidirectional fiber axis. Bending failure controls the chip formation in this process. Beam theory and laminate mechanics are used to establish the correlation between cutting force chip length and thickness.

iii) Continuous chip with built up edge It is similar to continuous chip except that the built up edge is formed on the cutting edge of tool. Built up edge refers to the welding of the work piece material on the tool due to high temperature and stresses. Factors Favorable to its formation a) high feed. b)low cutting speed. c) lower rake angle.

· MECHANICS OF CHIPS FORMATION Primary shear zone As the tool is forced into the material the chip is formed by shear deformation within a thin shear zone referred to it as primary shear zone which is oriented at an angle Ø with the surface of work as shown in fig given below. Failure of material due to plastic deformation occur at the cutting edge of tool resulting in separation of chip from the parent material. Bulk of mechanical energy of machining is consumed in this zone. The thickness of shear zone
