Forcing Long Hand Drilling Cycles

[Mick]

I have a C Axis VTL lathe post, with a Fanuc control. The drill cycles are limited, and as a result, we want to force the peck drilling cycle to be output longhand.

 

I've tried setting the Peck Drilling cycle enable to off in the Control Definition, and have also set the "usecannedpeck" or whatever variable it is ( ), but it still forces out the peck drill cycle. Is there something I am missing here?

 

I tried forcing all the drill cycles to off, but they still output.

Ok, scrub that last query. It helps to check which post you are editing, and which post you are using......

 

ARRGGH...LOL

 

Interestingly though, when I disabled it in the control definition, it didn't disable the drill cycles. They were still output as cycles. However, when I edited the post, they were output as longhand.

Mick,

 

Your post probably hasn't had the Control Definition switches enabled. Was it an updated V9 post by chance? Updating will make it X "compatible" but won't add some of the MD/CD logic. For that you need MPMaster or something like it.

 

HTH,

The Control Definition simply sets the initial value of various predefined variables (such as usecanpeck$). These values are then occasionally overwritten in the post processor inside of a post block.

 

An example of this would be in MPLFAN:

code:

---

pdrill0$         #Pre-drill postblock call

if cuttype = five, #Don't allow 5 axis, rests at toolchange

[

usecandrill$ = zero

usecanpeck$ = zero

usecanchip$ = zero

usecantap$ = zero

usecanbore1$ = zero

usecanbore2$ = zero

usecanmisc1$ = zero

usecanmisc2$ = zero

]

---

In this case, canned cycle output is disabled no matter what the CD setting is if you are doing a 5-axis toolpath.

 

This is not really tied to whether the post is an "X" post or an updated pre-X post. It is simply due to the fact that in the end, the code in the post determines the output.

Yes, I got it all sorted . Thanks for the replies guys

 

Paul, please check with your support department. I sent an email with a problem with the Mori Seiki MT Post Processor
