Hey Guys
I been using macro's for a while now, I did all kind of simple programming using macro's. But now i wanna try making whole part using macro programming. I have to make staright O.D Turn with chamfer & two grooves with top and bottom corner radius and i am stuck at chamfer and
radius macro's I don't know how to do that, I been playing but no luck.

IF you guys can help me out with your best knowledge, I be really thankful.

I have exactly what you are looking for with the chamfer. I will try to remember to bring it home tomorrow.

I have a seperate macro for grooving that will chamfer the top corners if you want that too.

I found it on my home computer so here you go.
This is the main calling prg. to turn the O.D. and chamfer both corners. I am only posting the first part of this prg. to save space. I wrote some definitions out to the side.

Post print with dimension I can try make one for you.

[mike9696]

Thank you guys for your time, Jon thee you are preety good with macro
Programming buddy, I'm gonna try this and i will let you guys know,
and i have to ask my boss if i can post the part drawing if not then i will just draw a sample drawing. once again thank you guys

[theemudracer]

Im gettin there. I have been programming for about 8 years but only 3 months with macro's.

It opens a whole another world in CNC programming.

I also wrote one that does a basic chamfer and puts radius's on the corners of the chamfer. I use this one on every part that I make on my lathe, parts ranging from .750 diameter to 2.5 diameter.

That one took alot of time for me to figure out.
