Abstract
This paper reports a fuzzy logic approach for chatter suppression in end milling processes. Vibration energy and the peak value of a vibration frequency spectrum are jointly used as chatter indicators and inputs to the proposed fuzzy controller. The outputs of the fuzzy controller are the altered machining parameters for chatter suppression. This approach does not require a pre-selected nominal spindle speed and has avoided the difficulties in selecting spindle speed modulation parameters present in several other spindle speed variation methods. Experimental results show that chatter can be effectively suppressed by altering spindle speed alone or by simultaneously adjusting feed and spindle speed. However, chatter cannot be suppressed by feed adjustment alone.
