The Surface Finish Specification On A Cast Iron Part In A Turning Job Is 0 8 Um Cutting Speed 75 M Min Feed 0 5 Mm 1
The Surface Finish Specification On A Cast Iron Part In A Turning Job Is 0 8 Um Cutting Speed 75 M Min Feed 0 5 Mm 1 (31.76 KiB) Viewed 42 times
The surface finish specification on a cast iron part in a turning job is 0.8 um. Cutting speed= 75 m/min, feed = 0.5 mm/rev, and depth of cut = 4.0 mm. Determine the minimum nose radius that will obtain the specified finish in this operation. What minimum nose radius will provide the specified finish if the part is a free machining steel, and what is this value if we use a ductile metal?
