Bandsawing is generally preferred over other sawing techniques (e.g., circular sawing) owing to its lower kerf width, higher metal removal rate and competitive surface finish. Investigations on machining Inconel alloys are generally limited to turning or milling processes with very little or no attention paid on bandsawing Inconel. The paper presents an experimental investigation on machining Inconel 718 using carbide tipped bandsaw teeth. The machining tests were carried out using a modified machine tool with a single bandsaw tooth. Cutting forces were measured during the bandsawing operation and the wear modes and mechanisms in the bandsaw teeth were investigated in a Scanning Electron Microscope (SEM). Abrasive wear, adhesive wear and some degree of plastic deformation were identified as the main wear mechanisms on the flank face of the bandsaw teeth. The higher depths of cut applied during machining could cause chipping or premature failure of the carbide tip in bandsaw tooth.
