hi,

we have a retrofit lathe with fanuc 0iTB mate control , we have a new job where we need to make a R8 radii , we are not getting this properly, we got a local programming guy to have a look at our program and he feels it's ok, do we need to ensure if any parameters are enabled to form radii. we have checked the axis for backlash and repetability and they r ok.

the program is as follows
G01 G41 X 256
G02X240.0Z16

any ideas

thanks again
rags

Well, being technical, but the syntax is important and unforgiving, your G02 is lacking arc center coordinates.

I think that´s missing R8 !!!

Here is an example of cutting a radius with cutter comp.

At the beginning of your Program there is no G54 WPC. Then you have G54 for two other tools. All Tools should be set using the WorK Shift not G54-G59 unless you are Flipping the part in the Chuck/Collet.

What is it that your trying to do?

BTW: Get yourself a Copy of NC Plot to Back Plot all your Text G-Code it is $75.00 right now until March 1st. It has been said to be better than Cimco Edit (Mastercam Plug-In). The Graphics aren't the Best, but it will save you and your Machine from any Trouble down the road. It also Supports Sub-Programs and Custom User Macros.

This was an example of cutting a radi, not a whole prg.

I use G54 on the Main spindle and G55 on the Sub Spindle for work offsets and program the part from there.

I barfeed 12' sticks into the lathe. Some of these parts have to be repositioned up to 4 times. To keep the Print dimenisions' and the prg. dimenisions the same I choose to use the G54-G59 work offsets.

I'll pass on the NC Plot since I do all my programming at the lathe. I have tried it and it does have a nice G-code editor.


Here is the entire prg with subcall Toby.....

Ok now it makes sense. I knew there was a reason for the X#. What type of Lathe, a Chucker or Swiss??

BTW: I seem to have replied to the wrong person's post too LOL. Read Rag's then replied to yours. Ooops!!!!!:wave: (chair)

This is the second time this month

It is a Hyandui Kia SKT250MS Chucker with collet noses on both spindles and 12 station turret with live tooling. No "Y" axis thou....

If only I had a "Y" axis I could do so much more with this machine.:banana:

Stuff like this?????
I used to work with these. A little hairy at times but never DULL
http://www.remsales.com/pages_blocks...machines/pages

[theemudracer]

those are a little more than a Y axis lathe .....LOL

The company I work for was thinking about a mill turn machine thou..

I would (nuts) someone to run one of those.....

This is the Machine that I run.
The picture is not accurate thou.

Just a little more LOL.

Hey you've got yourself a Nice Lathe. Boxed Ways Rigid.

Is that a Fanuc Control I see on it? Looks like an 18iT from here.

If you liked the last one YOU WILL LOVE THIS ONE!!!!!!

11 Full Axies I actually worked with an Older one of these down in Vero, Florida. NICE!!!!!!!!!!!! It didn't have the 5 Axis CAT40 though. Nakamura-Tome ROCK!!!!!!!

http://www.methodsmachine.com/docume...log%206-06.pdf

[theemudracer]

All I can say is WOW....

My machine has an 18-I tb

It is really rigid. I barfeed 12 foot sticks (LNS) ranging in diameter from
.750-2.5".

I also have an LNS Vacum unloader behind the subspindle. It can suck a pin 2.5" solid diameter 32" Long out of the subspindle and then dumps out and rolls out on to a table.

Thanks for the brochure. I will show the guys at work tomorrow.
