Long Hand Drilling Cycle w/chip break

[Brian Pallas]

I would like to get an output for a drilling cycle where I can specify : 1.How often to break the chip 2. Retract amount for chip break 3. How often to retract back to the clearance plane.

 

For example I want to be able to chip break every .100, and pull out of the hole every .300.  Where I used to work we had all Haas machines and you could do it with a G73 Q.1 K.3.  But at the new job we have Fanuc, Mitsubishi, Haas and Okuma controls.  I am thinking getting longhand output would be the easiest way to get that working.  But I am having trouble finding where in the post to alter the longhand drilling cycles.  

 

Any advice or help on how to do something like this would be appreciated.

 

Thanks.

This thread has some cool stuff in it...I believe there is a longhand cycle that would be easy to modify to get what you are after.

Fanuc

 

G74 R.000

G74 Z.000 Q0000 F.000

 

use this cycle on several jobs works well , very similar to the high speed peck on HAAS controllers

I would actually be interested in such a thing. I know you can switch it to long hand, that's easy. Adding the "K" parameter in there is going to be a trick.

the HAAS lathe manual shows using a "K" in their version of the G74

If you are so predisposed, I am sure this cycle I did not too long ago could be modified to work as you desire...

Thanks for the responses.  I am working on some other projects right now, so I will get back to this sometime in the next week or two.
