Turn G Code
« on: August 21, 2010, 12:10:21 PM »
I am trying to cut this profile could not get wizard to work so tried to write the code myself, should not be difficult but cant make it work for life
Am I working on the write principle using X as the shaft dia Z the centre of the radious K distance from 0, I radious?
Or can you correct me with an example
Thanks
Mike

Mike,
Actualy for turning you may want to try LazyTurn. Will not provide a profile cut but the rest works.
I am lazy...... ;)

Thanks for the info, the Arc Motion thread looks a very comprehensive answer to the issue.
I started using a cnc mill around two years ago and get on fine with it, thinking a cnc lathe would be a usefull tool
I converted an Orac to PC standards, but I am stugling with the lathe, as I find Lazy Turn complex to use.
Will keep trying
Thanks

There is a manual for LazyTurn which explains everything about the program.
You provide a dxf drawing of the profile,define tools, use that tool to do a rough cut, then a finish cut
and finaly post the code.Look at the appendix's as they provide additional information to the lathe user.
It's a slick program and a lot easier to use than some of the higher end ones.

You can get the profile code from LazyCam Turn and the appendix tells you how but LC Turn is
not as easy to use.
Keep at it you'l get on with it ............
