Omniturn CAN Cycle ( what the hell )

Hello everyone, I've been programing Okuma mill and lathe for more than 15 years now and this Omniturn G4 manual is killing me, figured everything out so far, but the damn CAN cycles I just don't get it. I want to rough something out and then finish with another tool using the same geometry. Can anyone out there explain it to me better than the book? Or maybe I've reached the end of my learning capabilities.
Thanks, Bob
 
Does it have anything similar to Fanuc G71, a rough turning cycle (which I call multiple turning cycle, to differentiate it from G90 which is a single turning cycle)?
 
I can sympathize with your feelings about the Omniturn manual.

What specific issues are you having with the can cycles? From my experience with the G3 control they work but maybe not the way you're used to.

You are describing the exact reason, shortly after I got my used Hardinge/OmniTurd machine, why I ended up removing the control and installing a Fagor 8025 on it. Frustrating is an understatement.
I put the OmniTurd control on EBAY and sold it for nearly what I paid for the whole machine. 2 months later the EBAY buyer messaged me and asked if I wanted to buy the control back at his substantial loss.......I declined! My thoughts are that whoever developed the OmniTurd software must have never run any cnc machines. It's far different from any other cnc controls.

I want to rough out with certain geometry with one tool, them come in and finish with another tool. Trying to use G75 or G78.
It says in the book I need to make the geometry a subroutine then the next tool will do the finish pass, but the program examples are very vague. Do you happen to have a program example I could look at to see how it's actually written? Any help would be great.
Thanks, Bob
 
What you want is, of course, possible on all controls.
Possibly on your control also.
Please post the examples, along with the figures, from the book which we can try to interpret.

This is how I do the Rough and finish with two tools,
remove the G70 from the first canned cycle and write a new cycle below it with only the G70 in it
 
This is how it is done.
But what do you mean by "remove the G70 from the first canned cycle and write a new cycle below it with only the G70 in it"?
G70 is not used inside G71.

my apologies sinha, I didn't quite phrase it right the first time round

Blobis,

Have you successfully used G75 and G78 without using the subroutine option? Can you post your code?

RT
 
Example codes from the manual also need to be posted. Then only, one can try to understand how they do it.
