| Abstract: | Aim To draw the relation between angles of cutters and their strength and stiffness. Methods The stress and strain of cutter with various angles (such as rake angle, relief angle, main deflection angle, assistant deflection angle and blade obliquity) under certain condition of fields of stress and temperature are analysed by the software ANSYS with lathe cutter as an example. Results The relations between angles of cutter and its strength and stiffness are obtained. Conclusion The accuracy of temperature stress coupled field analysis of cutter is better than the analysis of single field of stress. It puts up a new method in studying the theory of metal cutting mechanics and some effective attempts are made. |
