Peck drilll problems with Fanuc?

[Jimbo007]

I just bought a lathe with a Fanuc controll. i have never used the Fanuc controll, everyone says its the easiest and the best, but i am very confused. i am trying to peck drill at the end of the part. any pointers or sample programs? thanks.

Does the machine have canned cycle support enabled?

 

In the mplfan post you can turn on/off canned cycles. Without canned cycles you get a whole bunch of +/- Z moves to 'peck' in and out of the hole.

 

If you have canned cycles, I would guess it is something like:

G83 Z-1.0 Q0.1 F5.0

[Jimbo007]

yes my machine has canned cycles. also im trying to do this at the machine. i dont want to use mastercam.

Doesn't Fanuc have a number for support on its controller? that's where I'd try before anywhere else.

That's blasphemy!

 

Ever try looking in the Fanuc Operator's manual? It's quite comprehensive.

[Jimbo007]

the book has gotten me wayyy messed up.

I don't have a Fanuc Lathe Operator's manual otherwise I'd probably be able to clear it up.

 

Using MasterCAM and allowing it to create canned cycles out is probably be your best bet. Think of it this way, you'd be done already if you used Mastercam instead of going about it the manual imput method.

James teh smoke 'em if you got 'em

[Jimbo007]

your right. i am new to lathes. i have always ran and programmed mills. so i am kinda scared to do it in mastercam without knowing enough about the machine. pretty much im trying to take baby steps.

Jimbo,

one of the easiest toolpaths to set up in lathe are the drill cycles. so it would be a good place to start. no need to pick a drill point as mastercam assumes you are drilling the center of the part ( i am assuming a 2 axis lathe).ignore the X,Z feature on the parameters page for drill point when the page opens and just set depth, retract, and peck values. then post and see what you get.

 

HTH, phil

Jimbo, I am certainly not the sharpest tool in the shed but I taught myself how to use Lathe. Phil's right though. A drilling cycle is probably the easiest path to do. Actually you don't even have to have any geometry. You just adjust the depth parameters and post. Voila. BTW, if I had to write code by hand anymore, I'd have to find a new line of work.

 

for the effort Jim!

[Jimbo007]

can you put up a sample code for the drilling cycle?

[PE @ IHS]

Most Fanuc lathes do NOT have the G83 (full retract) option. You are stuck with the G74 cycle, which gives you a partial retract peck. If your machine does not support G83, then simply use the long-hand output. It gives you a long program, but the machine doesn't care.

Hi Jimbo,

Welcome!

It is clear you need help.As long as you are here you might as well learn to do it in Mastercam. Along the way you will find someone who knows exactly what you want. Let me know what I can do for you.
