Hi everyone,I'm exploring the possibility of retrofitting an older Reishauer RZ300E gear grinding machine by replacing its existing electronic gearbox with a LinuxCNC-based solution. I’d appreciate your thoughts on whether this is technically feasible—especially for someone with limited experience using LinuxCNC.Additionally, I came across this article on continuous generation grinding  and video(
) that outlines some of the machine’s principles. Could a setup like this be simulated and validated in LinuxCNC before committing to hardware implementation?Any guidance, suggestions, or shared experiences would be greatly appreciated!Thanks in advance.

I think this should be do-able, it sounds like this is a grinding-hob style of machine? I have been cutting gears with LinuxCNC for more than 10 years (since the idea of electronically synching spindles first ocurred to me) (I invented the idea of electronic gear hobbing, but I probably didn't invent it _first_ :-)

You could certainly simulate most aspects of such a machine using Vismach, but simulating the actual stock removal falls outside of the capability of Vismach.

Do you have an "articulated" 3D model of the machine?
