Effect of Speed on Various Machinability Criteria in Dry Turning of Nickel–Iron–Chromium-Based Superalloy
The present experimental work investigates the effect of cutting speed on various machinability criteria such as surface roughness, resultant machining force, material removal rate and chip thickness ratio in straight turning of nickel–iron–chromium-based superalloy (Inconel 825) using C-type and T-type inserts on manually operated lathe. The experimental results conclude that at 557 RPM, C-shape inserts provide better surface finish. Machining force decreases with increase in spindle speed. Chip thickness ratio decreases with increase in spindle speed.
