thx

he was making a heat sink type... the slots are about 10" long. but correct me if i'm wrong.. wouldn't the feed be the fpt X #of flutes X RPM? i mean for a cutter that has a diameter of .157 how much Chip load per tooth can it take?!?! 2 flutes! so that would be around what? 0.0032 per tooth? isn't this too much? the main reason of me asking u guys this is that am doubting the way i calculate my feed now... for instance i give the 1/2" endmill usually 0.005 chip load per tooth to calculate my feed. i know that wouldn't be the max the tool gives but i rather use than abuse the tools. so seeing a .157 run at about 0.003 vs my 1/2 running at 0.005!!!! i felt that maybe i should start pushing the 1/2 at 0.01 per tooth instead. but thinking that alone is freaky rather than me trying to do it for real on a machine... u hear me guys? so what is it then?!?!? i don't know.. help?

2 and again the tool was not profiling... slotting. thx man am chill.. just too anxious to know how they calculate high speed machining.

Hey guys.. is there anyone here really good in feed and speed calculation or someone who knows a good book he can refer me to that deals with this matter. today i was called by a friend to replace a broken tool. and i saw a shoking program 'to me that is' where the programmer was slotting .2 deep in aluminum using 5/32 standard carbide endmill at a feed of 60!!! The RPM was 9500. if i'm not mistaken shouldn't the feed at this feed and DOC be max around 30? am i missing something!!! i defenately am.. anyone who understands the math or whatever it is behind proper high speed feed and speed cutting for aluminum, brass, tool steel and such? buzzzzzz me plz.

i can't really get mastercam X either... too much mouse using it seems to me.. or am not getting it big time probably. 9. was faster i hardly touched mouse while using 9.0... but 10... i donno.. now am in this forum to findout what am i missing in 10. why was the interface changed so much in 10 anyone knows? it made it confusing... or to me it is more confusing i should say. all the short cut keys gone!!
