The equation: N = (3.82 x V) / D
N - spindle rpm
D - workpiece diameter
V - cutting speed (fpm)
From Machinery Handbook:
Uncoated cemented carbide tool (probably a ChiComm C5).
V = (520, 13) or (640,7) or (310, 36) or (345, 17). (X , Y) are (speed, feed) from page 994 25th edition.
workpiece is 316 SS 0.4 diameter. Target diameter is 0.375.
V = 310, N = 2960 rpm.
V = 520, N = 4966 rpm.
These rpm numbers are kind of high. Are they correct?
The power feed box has a min to max control. Would it be tacky to paste masking tape with feed rates (in/rev) on the feed box.
That would not be too bad. Just measure the travel for different dial settings. Who would do something like that?
The max rpm of the machine is 3000 rpm.
(In case you wonder why a simple question, I do checks like this once in a while for the fun of it....)
