I am trying to build a tool to simulate the position a 5 aixs cnc router spindle to avoid help collisions when programming/machining difficult shapes. (See image 1). The CAM software that we use only simulates the toolholder and not the actual spindle. The way I am initially approaching this is to…

Nothing here to to help avoid collisions. Cool animation over a bumpy surface though. [image] Confused measuring vector angles with optional plane Grasshopper No G-code in this thread from four years ago but some cool 5-axis stuff, as I recall. Ah yes, try moving the ‘A…

[image] Tom: Is there a way for the preview of the spindle to be visible whilst you move/rotate it to the right position then click to bake it into rhino? I think an easy solution might be GH Remote, that would allow to publish a “bake” button, and continuosly read the position of your “desti…

Thanks alot I this will be useful of all sorts of things. I didnt know about GH remote.

in order for GH to run in background and do as little interference as possible with the user, one way could be the Geometry Pipeline thing mentioned above it sort of continuously reads geometry from the opened Rhino file, and you can filter data based on layer and geometry type for instance, setti…

Thanks for the help, much apreciated. I started again this afternoon with a slightly different aproach to avoid the couple of bugs that I was getting. Still had a few issues but I think it is working better, just trying to impliment the GH remote that you reccomended. I think this will be good for …

[image] Tom: The CAM software that we use only simulates the toolholder and not the actual spindle. I’m curious as to which software capable of programming 5-axis lacks a machine model. That seems like a huge omission. It’s been my experience that trying to do this kind of stuff yourself can…

I am using RhinoCAM. It has a machine tool simulation but it doesnt work (only toolholder simulation), they told be that they were working on it. Even if they do get it working it wouldnt detect a collision of the spindle, only the toolholder. Its pretty budget software for 5 axis machining but I li…

Your definition in the post above is missing the input surface.

If you mean “5_axis_sim_004” you have to make a layer called TS draw a planar surface and name it TS in the properties then the geometry pipeline will recognise it and input it. Sorry just setting up it to work in GH remote. The first definition you manually set the planar surface

it needs cleaning up but here it is in a basic state with the GH remote added with cutter and toolholder definition. Thanks again for your help I think this will work well. let me know your thoughts if you get a spare minute. 5_axis_sim_005.gh (648.0 KB) One last thing, do you know what I need t…
