A Fanuc 6m or 15m post should be very close.

Hi Chip,

The code looks ok apart from :-

I would remove the G91.1 (G92.1 maybe?), re-run Mach and then try your g02/03

The only other thing I can think of is it may be a good idea to put a G90 on a line before your M30 just in case the other programs don't have it in the start up.

OK, give me a few days and I will dig out the routines, convert them from Fanuc macro code and post them in a Mach format for you.

Let me guess,

Your chess bishop is the problem!

Are you talking about a fixed ratio curve or an involute curve,  if its fixed ratio you can do it with 2 # variables and a sub routine.

If you want some code give me some sizes length/dia ratio and I will post an example.

Thanks Chad,

It will be about a week, I am just getting all the crap out of the control cabinet at the moment.

Quick question :-

What is the purpose of a 80mh 6A choke ?

Thanks

Hi Rory,

converting line drawings to a CNC program is not a problem there a several programs to do this, have a look at these web sites :-

www.softcover.com

www.vectric.com

As for the gears, it depends what type of gears you are talking about,  if they are none precision then maybe, otherwise no.

Give us more detail on the types of gears.

Hi Chad,

Thanks for the offer of help, I need it.

I am a mechanical engineer and software developer (payroll, invoice, database etc), my electronics is limited. Basic electrics is no problem.

As luck would have it I have a ModIO and a DigiSpeed XL, so it would be nice to use these,  by the way this is a mill so I will want to reverse the spindle for tapping.

I have had a look at the switching relay (RL3) and it is a 24V coil

The power rail in the machine has 5, 12, 24, 40 volt dc.

Thanks

Graham.

When using a CNC mill you have to imagine the tool is moving not the table,  this way the right hand rule works.


Right hand rule is

     +
     | /+
     |/__+

Thumb pointing right
First finger pointing away from you
Second finger pointing up

These are all your Plus directions

Graham.
