how can I use FC for cuntinuous 4th axis machining

[Anonymous]

Okay I have a simple enough part it's just an oval with about 20 90deg grooves that go around it. They are only about .015" deep I could write a program by hand that would do this easily but I have not been able to get FC to do it it either wants to try to do it as surface milling or gives me errors. Anyone have a thought on what am I missing?

Hi @Anonymous,

Can you share the part?

[Anonymous]

here you go this is the part the main reson I want to do this on the indexing head is it is hard to find double angle cutters this long that come to a small enough point.

Hi @Anonymous,

Is it around this I have marked "red"?

Hi @Anonymous,

See the attached file. NOTE you I have used mm tools.

Missing attachment so I can't tell what you marked in red. but probably there are a bunch of grooves going around it and that go down the length of it. It seams like it should be a simple part to make completely on the 4th axis cut the bottom off and machine the inside in a second op an be done. otherwise you end up with more setups. setups are time time is money

thanks JD i'll take a look and see what you did and get back to you in a few mins.

Thanks JD,

this works great but how did you go about it? Yesterday I had put a the surface on it like you did but rather than indexing it would just surface mill straight down without indexing around the part. I have a couple other sizes to do so need to under stand how to make it work. in the mean time I will continue looking at all your settings etc. and see if I can pick up what I've been missing.

Okay I missed that before, so I have tried it on  the grooves but it is still doing funny things like going way deeper than the surface indicated and then continuously indexing while the z goes up a couple thousandths at a time and X+ a couple at a time. gonna keep playing with it I never give up

thanks again JD

Hi @Anonymous,

I will take a look in the groove issue:-)

I think this would do what you need?
