Robotic manipulator machining standard step-nc part with LinuxCNC

Good night,

Thanks to LinuxCNC controller it was done a experiments with advanced language programming based in CNC technology. Standard CAD part was used to improve programming of industrial robots.





Regards.

Do you have any more details on this?

Did you write a pluggable STEP-NC interpreter for LinuxCNC?

Andy,

Sure, I am a lot information of videos content. We are working in new step-nc programming method for industrial manipulator, but that information only was published after accepted of scientific journal. I will sahre with LinuxCNC community.

The idea is to have a RS274NGC adapter for step-nc standard. Step-nc is a new language programming, a g-code evolution.

I am attaching a step-nc (p21) adapter manual, developed in java and integrated with LinuxCNC. But It only have 5 working-step features to machining.



Are you interested in make a project with community to develop a RS274NGC adapter for step-nc standard into running in LinuxCNC?

Regards.

To be honest I do not think that that is the correct approach.

LinuxCNC supports "pluggable interpreters". If you look, for example, at the sim/axis/canterp demonstration config you will see an example of a configuration that uses an example motion-control grammar based on the canononical motion commands. There is also a sample "not-G-code" file here:
github.com/LinuxCNC/linuxcnc/blob/master.../canterp_example.can

To use STEP_NC with LinuxCNC the best solution would be to use this approach, which means that none of the STEP-NC information needs to be lost during the conversion to G-code.

There is also a nearly-complete interpreter which could probably do the job.
code.google.com/archive/p/iso-14649-toolkit/

This was written by NIST and I think that the output is the exact canonical motion commands that LinuxCNC (also originally written by NIST) uses.

Andy,

Thanks for your explanation and LinuxCNC future development approaches with step-nc.

iso-14649-toolkit is a great solution, but is not update with recently changes from STEP-NC standard. Today there are a lot of standards (P21, P14, AP203, AP242, AP232...) with specific information to build a structure machining language.

I think to develop a step-nc interpreter for LinuxCNC or adapt "iso-14649-toolkit" will increase the applications (academic & industrial) with LinuxCNC controller having compatibility with modern programming languages based in CNC technologies.

Regards.

Hi everyone,

I am sending recently publication about STEP-NC standard based on OAC (Open Architecture Controllers). We were working with linuxcnc as g-code interpreter.

Again I suggest to community and available developers planning and developing an STEP-NC plugin/toolkit to integrate with LinuxCNC. G-code is a good solution for robot/machine programming but it is obsolete, for that reason it is necessary to update our controller (LinuxCNC) to keep it current for industry and academic applications.

Regards.
