New at Fanuc programming

Hello forum

My name is Matias and I'm from Chile. I have a few years reading differents topics of this great forum but now it's my time to ask.

In our company we bought an 2012 Doosan Lynx 300 with, obviously, Fanuc control (Fanuc i series).Here in the company have four Haas machines (TL-1, TL-2, VF-3, VF-5XT) and we learnt the CNC programming using the haas control.The basic programming is the same but the Doosan have other parameters that we don't know to use.
In the Fanuc control is it possible to compensate the taper? In the haas control its possible to make the taper correction from the offset pages using the (mayor diameter-minor diameter)/lenght. Does the Fanuc control have an option like this? In the Offset soft keys what is the "T" Value is used for?
Also, is it possible to make an manual tool offset without using the tool setter? For example, in the haas you can offset the "N" tool cutting the blank plus entering the diameter value.
Is it possible to make this in the fanuc control?

We almost bought an ST-30 instead the Lynx 300. It was a good option?

Best regards.

PD:Sorry for my bad English and if the principal idea is not well communicated

"Editing it" = adding a "U" value in your Z move.
U being the INCR value of X.

No, it is for sure incrementally adjusted.

I am not sure what you mean by compensating the taper. Are you getting taper over a length, lets say 3"? You compensate the taper in the program itself.

Yes you can manually touch off the tools by making a small cut and entering the values in the X or Z geometry offsets. Make a cut, mesure the diameter and enter it in the X offset column of the tool you are using and then hit the 'measure' soft key.

Matias,

As others have said, you cannot correct a taper from the offset page like on a Haas. You have two options. Both require changing the program. You can program a turning move like this:

G01Z-1.U0.001

This will move the X axis up .001 while making the cut in the Z direction. To change the amount of taper, you must edit the program.

The other option is to use another offset to control the taper. The program would look something like this:

T0101

G01Z-1.T0121

Set your second offset to the same data as in the original offset, but offset the X up or down by the amount of taper you want to correct. This way, someone can adjust the taper through the offsets and not have to edit the program.


To answer your other question, the T value in the offsets is the same as Tip on the Haas offset page. This is for TNRC. A turning tool is 3, a boring bar is 2, etc.

I hope this is helpful. I don't have any experience with Doosan machines, but I hear they are very good. I think your machine will be more rigid and more reliable than the Haas you were considering.

Thanks for your reply. I tried to measure the tool manually but I don't get how insert the diameter value. The "measure" soft key is locked (green letters) as you can see in the attached image.
