Fadal post issue, incremental drill depth

[Guest]

I have a rather large multiple part program written, well we need to run it in one of our Fadals(gulp)

 

I have many tool paths tranformed and set to output subprograms, which it seems to do nicely but all of my drill cycles seem to neglect the fact that the machine is in incremental and send the depth of all my drill canned cycles to and absolute depth.

 

Does anyone know if I am having a control issue or is there something my post my be missing to tell this thing what it is really supposed to be doing?

 

My code look like this

John,

it is something wrong in the post. I've fixed it before, let me see if I can find it and I'll post the fix here.

Curious Steve,

 

Did you ever get a chance to take a look at this?

Am I the only one that thinks it's odd to run a machine in incremental?

 

I've never seen that before.

In High Speed Machining - running in Incremental Mode will allow the control to process data faster because there is one less calculation to be made.

I was trying to get a program to fit into a small memory, so sub-programming with it being set to save memory room.

John,

 

I understand the concept of subprograms. It's the incremental part that I didn't get. What are the advantages of using incremental (since I know you're not high speed drilling?

simply, memory space.

No other reason on this particular job.

 

When you subprogram repeating patterns, I have found that using the incremantal machine mode is easier to use.

 

It is a multiple part fixture and the same hole pattern repeats in several locations.

 

They wound up moving it to another machine because even with all the space saving things I did it still wouldn't fit in the machine memory with everything BUT the hole patterns done in incremental and I didn't have time to explore setting up the DNC direct feed before I left on vacation.

*Now* I see! Incremental make the program smaller too. Brain fart.

I did a search and found this. I am having the same problem as John described at the start of this thread. Anyone know a fix? I'm using a modified Fanuc post

 

Thanks

Mike
