A lathe is set up to machine a taper on a bar stock 120 mm in diameter; the taperis 1 mm per 10 mm. A cut is made with an initial depth of cut of 4 mm at a feedrate of 0.250 mm/rev and at a spindle speed of 150 rpm. Calculate the averagemetal removal rate.
Added by Norman B.
Step 1
The depth of cut is 4 mm, so the volume removed per revolution is the area of the cut multiplied by the feed rate. The area of the cut is the diameter of the bar stock (120 mm) multiplied by the depth of cut (4 mm), which gives us 480 mm^2. Multiplying this by the Show more…
