ABSTRACT :

Chatter is a self-excited vibrations. Increased working speeds of machining produces excitation of oscillations and cause dynamic problems. Chatter reduces the tool life, produces poor surface finish, reduces productivity and increases rejections. The experiments performed in this experimental work describes the method for obtaining stability lobe diagram for milling operations and this to help operator in selecting combination of input cutting parameters, viz., depth of cut and spindle speed for chatter free machining. Vibration analysis technique is used for these experiments. Experiments are carried out on vertical milling machine and vibrations signals are acquired using accelerometer. AA-6061 material is used for workpiece. The results obtained shows that, vibration analysis is simple, easy and efficient method for obtaining stability lobe diagram which helps operator to select combination of input parameters, viz., spindle speed and depth of cut for chatter free maximum material removal rate.  

Keywords: Self-excited, chatter, stability lobe diagram, material removal rate, accelerometer
