Cutting Parameter Optimization for Minimizing Machining Distortion of Thin Wall Thin Floor Avionic Components by Changing Of Tool Material
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 8
Abstract
Distortion of thin wall thin floor aluminum components during and after machining is one of the main challenges faced by aerospace manufacturing industries. These parts have to be machined from prismatic blanks to features with walls and floors as thin as 1.5mm. So, in this experimental study series of machining experiments were carried out using Taguchi design of experiments to find the effect of important machining parameters (speed, feed, depth of cut, width of cut, tool path layout) and the influence of coolant to reduce the temperature of tool which influence distortion of the parts during machining and optimize them for minimizing distortion. An L’16 orthogonal array, signal-to- noise (S/N) ratio and ANOVA are utilized in this study. By this approach both the optimum parameters and main parameters which influence distortion can be found. Optimum parameters are finally verified with the help of confirmation experiment.Al6061T6 is used as a testing sample to provide machining on different speed and feeds with different tool paths preparing in cam, fixtures also play an important role in clamping the object which can make a little distortion at different levels. Tool wear can be checked with experimental results as t6 materials are highly used in avionic components.
