is there 5 axis
hello , i am building my own 5 axis machine XYZ AB , so is there 5 axis option ? if not will it come to future ?
Re: is there 5 axis
I'm working on 5-axis algorithms.
I made an inverse kinematics solver for 5-axis (and n-axis) machines and cutting algorithms. My focus has been core algorithms - nothing's been turned into a FreeCAD workbench yet. I would welcome help on workbench-ifying this.
I'm getting close to making chips fly running adaptive pocketing on arbitrary planes on an physical 5-axis machine.
The inverse kinematics project is here: https://hackaday.io/project/169499-solv ... h-modelica
( The tutorial might broke now if you try to follow along unfortunately...)
In addition to the IK project there is a higher level python modules where the algorithms like adaptive pocketing live called HackerCAD. HackerCAD runs in a Jupyter notebook and uses the python-occ library.

Re: is there 5 axis
i was programer i would help but i am not , i am just building cnc machine with XYZ AB for medical use as hobby , i was using fusion 360 but they decided to kick all free user with more limitations no export step etc , so i decided to moveto freecad hoping there would be 5 axis milling system , and post-processor generator

I just read about the changes this morning. They really made the CAM almost unusable for hobbyists.nesquik011 wrote: ↑Thu Sep 17, 2020 9:19 am i was using fusion 360 but they decided to kick all free user with more limitations no export step etc , ...
I wish we had better simultaneous 5 axis milling for you but at least we can give you rapid moves and tool changes for free and the 3+2 milling (4th axis stuff) is getting better.

so it means there is a hope for 5 axis in the future ? is it possible ?sliptonic wrote: ↑Thu Sep 17, 2020 2:45 pmI just read about the changes this morning.

Re: is there 5 axis
Of course it's possible. In fact, it's almost inevitable. It's just not likely any time soon.
Open-source software is relentless and unconcerned with schedule. Everyone on the FreeCAD project could get hit by a bus and someone else would pick up the code base and continue the work.
I personally plan to work on this project for a long time and I can't wait to see how good it is in a couple of years but unless we get developers willing to tackle those hard 5 axis tool paths and sponsors willing to make 5 axis machines available to developers, it might be a while before that particular feature is ready.

Re: is there 5 axis
.
Isn't this problem really a matter of seeing with your own eyes how the tip of the milling tool moves in space?
If so, I'd say we design a small and simple 5-axis machine made for 3D printing. Then it would be "just" a matter of getting your hands on a printer and some stepper motors.
I mean, just to make the code working, you shouldn't need a perfect real Mega $ machine, right?
5-axis milling for the people!
Re: is there 5 axis
Probably right, but it is more fun for a programmer if he can use it himself. What else would be the payback if not fun?Pauvres_honteux wrote: ↑Fri Sep 18, 2020 9:25 am I mean, just to make the code working, you shouldn't need a perfect real Mega $ machine, right?

Re: is there 5 axis
Hi Pauvres_honteux ,
Hi sliptonic,
i think one 5 axis machine isn't enough, because there are different types of machines out and i think they need differnt code to.
Since about 2 years now i'm thinking about building a little 5 axis router, but i'm not sure how to build the B axis...
A turns the bridge of the router, but for B i'm changing between turning the spindle or just turning a part of the table. Turning a part of the table would be more easy, turning the spindle allows bigger parts.
But for buth machine types the code must be different to in my mind...
Is there a 3D printing system which needs/uses 5 axis ? I don't know one...

Re: is there 5 axis
i am happy to see that there is a hope that freecad will get sooner or later 5 axis cam , 5 axis cam for everyone , and i am sure after what autocade did XD this community will grow more , i working on youtube channel for cad and cam stuff based on fusion but after that i think i will move to freecad so thump up to freecad , at the end i would love to say developer don't give up on updating the cam system
