problem making angles

[Justin Cavender]

i am tryin to do a guitar body and i am having trouble making an angle. I have attached the file in a zip it is on th top the diagonal line I want to chamfer from there to the edge but I dont know how to do it.

You could try this model, I've made the chamfer.

There's a new plane for that.

You can modify the sketch as you like for the right chamfer dimension

Just did a extrude cut, goto solid tab and regen with new selected sketch chamfer

Hope this help and hope you'll be able to load with Mastercam

Thanks jeffrey. How can all that be machined in one setup? when I got to the original top view in view manager and try and select the chamfered face for a toolpath it say does lie in the construction plane.

You will have to machine the chamfer from the top plane.

If you make a plane from the geometry, you will have to place the guitar body at the same angle on the table, which is not an easy thing to do.

You can machine the chamfer from the top by selecting the chamfer surface only and use a toolpath for it.

You can draw geometries from chamfer and use as containment boundaries when machining.

I just made some tool paths for you to analyze.

They are not the best because they would needs some refinements.

It is machined from the top plane.

Look at level , made some modifications for the Stock setup to have the solid as stock.

Made another level to have geometries for containment boundaries.

Made surfaces from solid to be able to have check surfaces.

Just used a .5 ball end mill, you can choose another.

Changed the machining angle, just used something similar to the same angle as the chamfer, you can change it either to be parallel to the surface.

Hope this help, Jeff. This all the time I have
