Abstract: | In the present work optimal tooth spacing vs spectral redistribution criteria for face milling has been used as one of the methods for vibration control. A special milling cutter with non-uniform pitch has been designed and fabricated and its effect on machine tool vibration is studied. The frequency response spectrum of the machine tool is found out analytically using Finite Element Programme. The spacing between the teeth of milling cutters is found out by minimizing the total power of the relative cutter-workpiece vibration. The newly designed cutter is fabricated and tested experimentally to determine its effectiveness when compared with a standard cutter with evenly spaced inserts. |
