Project Summary

In this research, the main focus that is under discussion is to study the effect of cutting parameters such as speed, feed and depth of cut on the machinability of AISI 316 using more advance technique Response Surface Methodology (RSM). RSM with Central Composite Rotatable design matrix will be used to optimize the cutting variables.

In present work, we will develop machinability models that will define functional relationship between independent input cutting variables (speed, feed, depth of cut) and the output response (surface roughness) of machining process.

The main aimed of this research is to evaluate the performance of Neem Oil as a cutting fluid for machining of AISI 316. Carbide cutting tool inserts were used under different parameters by using different cutting fluids such as Neem Oil and Conventional cutting fluid for machining. The performance of prepared cutting fluid will be compared with that of conventional cutting fluid. At the end, the results for both the cutting fluids during turning of AISI 316 will be compared with each other.

All the experiments for this study will be conducted on CNC Lathe machine with a tool holder MTJNR 2525M16 and a carbide tool TNMG 160408-M3 TP 2500. The dimension of the AISI 316 workpieces are 20mm in diameter and 60mm in length. Total 20 experiments are conducted for this study and three measurements of surface roughness will be taken for each experiment to take average value that is used for further analysis. The Surface Roughness for these pieces will be recorded and measured by using the Surface Roughness Tester.

Benefits of the Project

So our main goal is to gain lower machining cost by enhancing quality and productivity. So in order to achieve this we have to work on the parameters such as greater cutting speeds, extensive tool life, least part rejects (scrap) and lowest downtime.

So by the application of cutting fluids the gain which is possible provides higher cutting speeds and higher feed rates. In general the fruitful cutting fluids not only provides just the enhanced machining performance but also the environment related problems such as the toxic and harmful exposure to living organism especially the workers and also the aquatic life, Otherwise it leads to the danger of contaminating the water beneath Earth as well as killing of aquatic animals.

The main reason that mineral oils are being used and using presently is their availability and they are reasonable priced as well.

The drawback mineral oil have is its poor biodegradability which is that they holds the main reason of long term pollution in the environment. Additionally, their obtainability is dependent on the political deliberations.

Consequently, prevailing credits do not promise to us for the obtainability of mineral oil in the forthcoming.

So biodegradability demand has increased a lot to overcome all the drawbacks by deploying the vegetable based cutting fluids instead of using mineral based oils. Mineral based oils are limited and steadily declining resource whereas the vegetable-based oils are sustainable.

The reason why vegetable-based oil attracts the industries is the quality of being eco- friendly. The output which can be gained through vegetable base cutting fluid is the improved surface roughness, reduced tool wear and temperature generation at cutting zone when compared to mineral oil.

Technical Details of Final Deliverable

It is observe that the surface roughness is mostly affected by feed rate and increase when the cutting speed is higher. To minimize the surface roughness feed rate has proved the best machining performance. For machining parameters Response Surface Methodology is used and desirability functions are used to optimize the surface roughness value.  The surface roughness parameter increases when the feed rate increase while decreases when the spindle speed and depth of cut increases. It can be noticed from the all the experimentation that while increasing the depth of cut and speed, the RSM parameters decreases but by increasing feed rate the parameters increases and vice versa. It is outward from the analysis that feed rate has the substantial contribution for both speed than materials. For specified ranges the optimal parameters for several responses were inwards to input parameters using desirability index. The most obvious factor is feed rate to get minimum surface roughness.
