i.m new to this site
i have an okuma captain L370 lathe and am trying to mill
a hex on the end of a shaft. the hex comes to a shoulder and
i am able to produce the hex but the flats appear rounded or
it looks like maybe the corners may be milled away a bit causing
the flats to look rounded.
i have milled a bigger hex on an other part using the same program
but this time it doesn't appear that i have the feed rate figured right
or maybe i need to use a different programing method.
any example programs or easy methods of calculating the feed would be helpful. i'm running a 1inch 3insert cutter milling a hex in stainless steel that is .830 across
the flats and .930 across the corners .340 deep
i'm running 2600rpm and feeding f18
any thoughts or advice
thanks in advance
