In this paper the feasibility of fabricating spiral carbide tipped end mill adhesive using bonding technique has been investigated. Cutting tests were performed and cutting forces, vibrational motion, tool wear, and surface roughness were measured. The cutting performance of the bonded end mill has been assessed in relation to those of the brazed tool. This investigation shows that the performance of the bonded end mills is almost identical to that of the commercially available brazed ones in both cases of normal cutting conditions with and without coolant. The vibration characteristics show that the damping effect of the bond layer is insignificant due to dimensions and geometry of the bond line. Infrared prints demonstrate a pronounced heat isolation due to the low thermal conductivity of the adhesive, which can be improved by mixing metallic particles in the bonding material.
