V9 Lathe - OD Finish vs. ID Finish

[CNCGUY]

Is there a way to differentiate (SP) between OD and ID finish pass?

 

I want to make sure the tool is out of the hole for ID work (without using ref. points), but dont care on OD work!!

Thank you

in RoughParameters or FinishParameters window, there is a tab of RoughDirections or Finish Directions there you can play around.

I set up stock in job setup. Mc will know its on the id then.

MC will know its on the ID, and happily crash into the stock every time. I'm sure it is possible, Troy; but really, how hard is it to click Ref Point and plug in Z.250?

[Bryan Johnson]

when the stock definition is used, a reference point is typically not required for ID work.

The move in and out of the bore will be automatic.

 

But to answer the question, I do not see that it is possible to seperate defaults between OD and ID for finish.

Chris,

 

For me its not that hard, but I dont do much of the programming any more.

 

Brian,

 

We do define the stock. The problem is - the first operation may remove more material than the second op. Therfore MC thinks the stock for the second op is gone and the tool will rapid to tool change position from inside the part.

 

I have added a safe guard "G00 Z.05", but that applies to all operations, not just I.D.

 

Hope I explained this clearly enough.

Troy, as a rule I send all tools .250 in front of the part before they go home and I use ref points to do it; unless your machine is really slow or the parts are really long I see no reason not to just tell your programmers 'retract to Z.100 or Z.250 EVERY TIME' and expect them to program the part correctly. I'm sure that when you click over to 'ID' for those bores Mastercam spits that info somewhere but I don't know how you can access it; probably something to do with interpreting the NCI files which I have made no effort to understand at all.

Check to see if yur tool clearance is set in the properties.

I haven't used ref points since V9.

Just a guess!

CNCGUY,

Methinks you can differentiate between ID and OD in the post. at least we could in V9.

 

Something like:

 

p_idtool # auto ID tool retract 12-01-94

if old_orient = 4, "G00Z.2", e$

if old_orient = 8, "G00Z.2", e$

 

where old_orient was set equal to orient previously cuz i thing orient is updated to the next tool orientation before this postblock is called

 

I use the postblock in order to be sure that my ID tools are clear of the part befor homing and/or indexing the turret.

Charlie,

 

Thanks for the info. I will have to look into that more and see what I can do.
