A 6-in. long, 0.5-in. diameter 304 stainless steel is being reduced in diameter to 0.480 in. by turning on a lathe. The spindle rotates at N=400 rpm, and the tool is travelling at an axial speed of 8 in./min. Please calculate the cutting speed, material removal rate, cutting time. Results:
|
v=fN f=v/N
MMR=pi(Davg)(d)(f)(N) t=l/fN |

You have to mill a titanium alloy. For this you are using a cutter with a diameter of 3 in. and 10 teeth. From the Tables you have:
• Speed for Titanium alloy = 200 ft/min • Feed = .006 in./tooth Please determine N (rpm) and v [linear speed of the workpiece] in (in./min) Results: |
N=255 rpm
v=15.3 in./min |
|
Assume that you have to perform a face milling operation (see figure) & assume that D=150 mm, w=60 mm, l=500 mm, d=3 mm, v=0.6 mm and N=100 rpm. The cutter has 10 inserts and the workpiece material is a high-strength aluminum alloy. Calculate the material removal rate, cutting time, and the feed per-tooth, & estimate the power required.
