4th axis V9

[Flycut]

I put a file on th FTP site in the MC9_files folder called 4th axis vic.

If anyone has a second I'm sure it would be quite simple.

What I have so far is 3 operations and 3 work coor. but I think it can be done all in one shot, I just don't know how.

Any help would be nice.

Thanks again guys!

You could use 5 axis curve. Make some vector lines to control the tool for you. Then make the output 4 axis and it will do all 3 chains as one operation.

Multiaxis flowline with 4-axis option.

Check out 4TH AXIS KANNON on the ftp next to your file and tell if its what you wanted.

[Kannon]

by the way... used curve 5axis output as 4axis

Yeah that's exactly what I'm trying to do.

Trying to go with what Millman and John are telling me but with little luck.

I see you have some cross lines drawn up. I guess those are the "vector lines" Millman was talking about.

I'm goint to have to learn how to do this because I have 40 other parts similar to this one still to go.

 

Thanks guys.

I'll play with that file and see if I can mimic what you've done.

[crazy^millman]

Without looking at what he did that will be your lines and those lines control the normal or 4th axis position relative to the cut as you are going around the part. Now is this for a cam follower? If so I think you might be headed down the wrong path. If not then you should be good.

reselect lines used for vector lines.. then mix it up a bit and see how the toolpath reacts...

you can literally turn the toolpath inside out.

 

glad its what you wanted.

 

I am always learning also and wouldnt have got it without Rons tip on creating vector lines for toolpath control.

 

I never tried that path..

Thanks.. I also learned something new.

flycut..

 

Id be happy to give ya a hand if you have any problems with those to come.

[Flycut]

Thanks buddy.

I'm getting closer to what I need.

I found that after I posted the file the code was not comming out like I expected.

There were way to many "Z" and "Y" moves.

So far 3d contour with rotary axis substatution seems to be working .The only problem now is my "A" axis is going to fast for the programmed feed.

4TH AXIS KANNON 1

 

on the ftp... almost got away with unrolling it..

flattening it... toolpathing and rolling it back up but it looks like it will gouge the sides were the radius runs to the flats.

[Flycut]

Well axis substitution was working on a few parts but they were less then 180 degrees and had no flat areas.

 

I tried to use surfaces for tool axis control and it seems to work well except for the areas it decides to skip. Anyone have a clue why it would skip spots when I use surfaces but not when I use lines?

 

[John Summers]

Sorry, Flycut, I was looking at the surface, not the edges. CURVE5AX is the right way to trim the edges. The surfaces must be extended, or the toolpath runs off near X=0. Create surfaces from the solid, delete all but the 3 surfaces you need, and run CURVE5AX. E-mail me if you still have trouble. I'll send you my part.

[Flycut]

Thanks all.

I'm flying now!

 

In the end, extending the surfaces and using projection normal to surface in my geometry (as per John's advice), did the trick.

 

Kannon,

Let me know if you'd like to see the final file I used.

[Kannon]

i WOULD like to see..

[Flycut]

You got mail.

 

It isn't the same file I had put on the FTP site.

This is the last one I just did.

Works great!

[Kannon]

Thanks for sharing it...
