Abstract
Vibration affect tool life and machine tool spindle during machining of hardened material. Chatter in machined surfaces that affect the surface quality and dimensional accuracy of product. This paper present way to deal with determines vibration examination on machining of monel (K-400) material during end milling process. Monel alloy 400 is a nickel-copper alloy which combines excellent corrosion resistance and added advantages of greater strength and hardness. Typical applications for monel alloy k-400 products are fasteners, springs, pumps and Values. In this investigation spindle speed, feed and depth of cut selected as an input parameters and Feed acceleration is consider as response parameter. Tool wear rate is also investigated during end milling operation of monel alloy. The vibration test was carried by vibrometer and amplitudes were recorded with different spindle speeds of CNC vertical milling machine. The test were conducted various combinations of spindle speeds. The experimental result shows that spindle speed is the major factor that affect the tool vibrations. Analysis of Variance of feed acceleration was shown to predict vibrations during machining of monel (k-400) by end milling process.
