yay, i made something useful. its a clamp for my new 2" tool makers vise. i did this one in jog mode. now i need to write a program now to cnc 3 more.
im a bit puzzled how to part them off. i could turn it sideways and mill them off, but thats a bit of a waste of material. i imagine a slitting saw is the ideal way, but i havent got one handy. could bandsaw them and then do a clean up pass - but my bandsaw is a bit crap for metal. hmmmmm.
thoughts?
also, i statred the job with an m42 3 flute cutter. it worked well enough, but started to overheat doing the deep slot, and eventually died trying to plunge the hole. only did the hole cause i knew it was near dead anyway. so i switched to a carbide 2 flute end mill. what a difference! the finish on the side cuts is amazing, chips come of silver, runs slightly faster feeds and seems to actually deflect less on deep side cuts giving a near mirror finish. we'll see how it holds up now on the next 3.
