Fagor F04

[Leanna Perr]

Helloeveryone. I'm new to CNC Turning and I'm looking at buying a GT-27 type lathe with a Fagor 8025T or 8037TS controller. After a search on this forum and other places I haven't found any good information on a reliable post processor for Fusion 360 Turning CAM.

Thanks for the reply. I've looked through most of the threads in the post processor section and the only one I found that related to my problem was from Tactcal Keychain from a few years ago. He never did get a Fagor post that worked well. I believe the last post he got wouldn't do threading. Fagor seems to be a popular lathe controller, is there anybody out there using Fusion 360 turing cam with it?

Yes I contacted him on youtube and he doesn't have a PP yet. He is working on making his own. I guess no one out there is using fusion turning cam with a fagor controller. That is crazy as most of the GT-27 type lathes I've seen use the fagor. Can anyone from Autodesk let me know why a PP hasn't been made for Fagor yet? I see that even Tormach has a turning PP available.

I think a good bit of people would want a Fagor post. One of the companies selling rebuilt GT27s claims to have asked autodesk and will have something soon. Not sure this is true based on the sales experience I had with said company but I know they are aware it would help them sell machines. I am running a Haas now with a mix of hand code and Fusion with good results. I have a fagor machine on the way and hope to be doing the same. Who do I ask for post help and what do they need? Fagor has some good lit on line as well as sample code.

I was working with two different Post Processors for a Fagor 8025T. I have the manual and put together a comparison between two of the post processor output file from Fusion 360 of the same machining path. The third code is a sample from the manual I have of a different geometry

I am not good at reading Gcode and was wondering of the two post processor output code which one best matches the format of the sample code? Does it look like one or both of the fusion 360 generated code would working for a Fagor controller?

I need a post for a 5 axis fagor 8055 controller on an old Motionmaster machine without TCP. Where the post needs to do the tool tip calculation (requiring one to enter the distance from the C axis pivot to the spindle face into the post processor code).

You would probably be better off using the thermwood.cps post processor as an example of adding code to the Fagor post to offset for the head pivot distance. You should probably be able to copy the onRapid5D and onLinear5D functions as is into the Fagor post. You will also have to add the following code in the onSection function.

Thanks again for response. I went through the post as you suggested and get reasonable code that does run the machine HOWEVER, it is not compensating for the headOffset...no matter what I enter for the pivotDistance I get identical code.

When I run the code on my machine it disregards pivotDistance and seems to act as if the value is zero. It just turns the C and B axes and goes to town without offsetting for the tool and pivot length.

I've attached my post processor file if anyone could take a look and see what I'm missing, I feel like its super close! I was so pumped to get some real working code out, now I just need it to happen in the right place!

The Thermwood post is setup to use tool length compensation with 5-axis (G43), therefore the tool is translated back down where the tool tip would be if the Head axes are at 0,0. The reason behind this is that the control will compensate for the tool length along Z, but not along the tool direction. This is a typical method to use with this style of machine. If you need to output the coordinate at the pivot point, then you would not only have to comment out the following line in the onLinear5D and onRapid5D functions.

You would also need to add the pivot distance in other locations within the post, i.e. the initial position in onSection, onLinear, onCircular, onCyclePoint, etc. The 5axismaker.cps post processor has a function called 'get5DPosition' and you can see that this function is called in all the appropriate functions. This machine actually has a C-axis that is offset from the B-axis, which is why this code is required. You can use this post as an example if you need to output the pivot point location, but you will have to modify 'get5DPosition' with the code from the Thermwood post, along with commenting out the above line.

Thank you for your help. None of these fixes are generating usable code for me. I've been told that The DMS 5-axis/Fagor 8055 controller doesn't require a pivotDistance variable. If you were able to generate code then why can't you just supply the post right here in this forum?

We are currently working on 5-axis DMS router posts for both the Fagor 8055 and 8065 controls. These are still in the validation stage, I believe the status is that the 3-axis and 3+2-axis have been tested on a machine, but not the simultaneous 5-axis. I am attaching the post here if you would like to test it, but please use extreme caution when running it on the machine for the first time, as it has not been fully tested yet. You can report any problems that you find with the post on this Forum thread.

This post relies on TCP programming (G48 S1) and does not adjust the output coordinates in relation to the pivot point and you must enable the 'fiveAxis' property to support the 5-axis capabilities of the machine.

We do have a post processor for the DMS 5-axis Router with a Fagor 8065 control currently in Beta testing. If you would like a copy of this post for testing, then send me a PM with your e-mail address and I can send it to you. Of course, this post is still in Beta mode, so use extreme caution when running it on the machine.

Other than the single axis 10i, the 20i is Fagor's lowest level digital readout with 2 axis available.The DRO itself is almost identical to the 30i/40i, but offers a few less features. The 20i is a great choice for someone looking for a high quality, but lower-cost DRO system.

The 30i comes in kits for milling, turning, and grinding applications needing 3 axes. It is available in 3 axes only and boasts a 5-Year Standard/ 3-Year No-Fault Factory Warranty.The DRO itself is almost identical to the 40i(3axis), but offers a few less features.

Complete with a larger color display, the 40i was built with the user in mind. It has all the features needed to boost productivity on your boring mill, VTL, or long-travel lathe. The unit is available in 2, 3, or 4-axis. For lathe applications headstock and carriage mounts are available. If your application requires longer travel length than available in the fagor kits, please contact us for pricing on a custom kit. Like the 30i, the 40i also comes with a 5-Year Standard/ 3-Year No-Fault Factory Warranty.
