First posting for me. I appreciate any feed back. I am fairly new to Gibbs. I have only done simple hole drilling and pocketing with version 7.3.5. I have attached a .dxf of a dome I need to surface with a ball mill. My question is how? Also I can import a 3d Inventor drawing into Gibbs of this part. Will it be easier to set toolpath to a 3d rather than drawing it in gibbs?
What mill package do you have? (mill only, 2.5 solids, solid surfacer)
Your file looks like a 2D drawing exported as a dxf file. If you have solids all you need to do is extrude the base, create a primitive sphere, slice it at the top of the rectangular base and do a boolean addition. From there you have several ways to surface the dome. If you need help creating the file I can post it for you.
Here are a few quick toolpaths for the dome only. For the Contour process go to the transform toolpath plug-in and do a copy and rotate. The downside of this technique is each copy will be a seperate process tile. Read through your Solid Surfacer manual and do the tutorials. They will get you started in fairly short order.
