The appropriate methodology adopted for the design of single point cutting tool is an important aspect of tool engineering. It deals with the design of tool shank, design of single point cutting tool, and various forces involved during machining of the workpiece. Selection of the appropriate material for the design of the single point cutting tool is paramount important and consideration must be put emplace.Various aspects of tooling, material cost, fabrication, manufacturing methods and the proper functioning of product should be considered. Strength and rigidity of tool is also taken into account while designing single point cutting tool. The main design criterion for shank size is rigidity. The deflection at the cutting edge is limited to a certain value depending on the size of machine, cutting conditions and tool overhung.
