Experimental Investigation of Cutting Tool Vibrations by Replacing Various Thermoplastic Gears and its Comparison with Metal Gears in the Feed Box of Lathe Machine

摘要

The load coming on feed box gears in higher depth of cut, during machining and threading operation produces vibration which finally transmitted to the tool post. This causes impact on surface finish of machined components. The good damping and self lubrication property of engineering thermoplastic gears reduce cutting tool vibration to the great extent. An attempt has been made in this regard by experimentation to evaluate vibration occurred on tool part by using different engineering thermoplastic gears as replacement to metal gears. The paper present the comparison of vibration occurred on cutting tool during machining operation using various depth of cut and spindle speed. The outcome of the experimentation may helps to reduce maintenance cost, noise level, cost of lubrication and increase in the accuracy of machine tool. The advantage of material property helps to produce zero defect components by providing more tolerance level and making machine tool more productive and cost effective.
