Effect Of Lathe Machining Parameters On Machining Characteristics Towards Mild Steel (AISI 1020) Using RSM

This project investigates the effect of lathe machining parameters on machining characteristics towards mild steel (AISI 1020) using Response Surface Method. The machining parameters selected on the experimental project are cutting speed (75m/min – 125m/min), feed rate (0.2mm/rev – 0.4mm/rev) and de...
