Turning Parameter Optimisation using Taguchi Method

Approx. component budget: Rs. 5,000 - 9,000 + lab

Objective

Find the best cutting parameters for the lowest surface roughness and the least tool wear using the Taguchi method.

What you will build

Round bars of mild steel or aluminium turned on a lathe with carbide inserts at different speed, feed and depth of cut, following an L9 orthogonal array.

Results you can expect

• Surface roughness and tool wear for 9 runs
• S/N ratio analysis
• Best parameter set
• Contribution of each parameter (ANOVA)

What you will learn

Machining, Design of Experiments, Taguchi method and ANOVA, widely used in manufacturing and quality work.

Tools and notes

Lathe, roughness tester and tool microscope (college or outside lab), Minitab or Excel. Wear safety glasses and follow lathe safety rules.

Resume points from this project

• Built and tested Turning Parameter Optimisation using Taguchi Method; objective: find the best cutting parameters for the lowest surface roughness and the least tool wear using the Taguchi method.
• Measured and analysed surface roughness and tool wear for 9 runs and S/N ratio analysis; wrote the report and presented the results in a viva. Add your own numbers: [x].

Replace [x] with your own measured results. Write only what you really did.
