Study And Analysis Of Single Point Cutting Tool Under Variable Rake Angle

The finite element method is used to study the effect of different rake angles on the force exerted on the tool during cutting. This method is attracting the researchers for better understanding the chip formation mechanisms, heat generation in cutting zones, tool-chip interfacial frictional characteristics and integrity on the machined surfaces. In present study the three different rake angles are studied to find out the variation in values of Vonmisses stress for the specified applied forces. As we increase the rake angle then the value of Vonmisses stress goes on decreasing. The value of Vonmisses stress decrease for increase of rake angles of 7°, 9° and 11° respectively. From results it seems that reduction of resultant forces might cause increase in tool life but it cause decrease in tool life. In present study mesh is created in ANSYS and the boundary conditions are applied and the analysis is carried out for the applied constraints. The results calculated on software can be verified with experiments carried out with tool dynamometers for lathe tool. For future study the applied model can be used for multipoint cutting tools such as milling cutters, broaching tools etc.
