Best Toolpath for cuting raised letters on a concave and convex surfaces?

[nickelback]

What is the best way to machine raised letters and raised detail on a concave and convex surface? The geometry is an imported solid model. I tried to use the fnish project, but have not gotten good results. I keep getting an error message. Am I doing something wrong? Is there a better toolpath that would work for me? The part is small and I need to use 1/16 and 1/32 ball endmills. I did get good results with Surface,Finish,Radial. And than use Finish, Surface, Contour to clean everything up with the 1/32 ball endmill. If there is a better way to do this please help! Thank You

Look at surface finish scallop for this task you might like the rexxxxs better. It would help us to help you if we had a file. If you got soemthing to put up on the FTP we call can take a crack at it.

I saved the file in the MC9 files folder and the file is called A-half letters asm. Thank you

I cant get to the FTP site.

 

Try surface rough rest mill.

Or surface finish leftover.

With your second tool.

Why wouldn't Surface Finish Contour work for finishing the letters?

[Teh Bear without Brains kinda idiot]

I would make pocket operations (First mill regular pocket and remachinig for next ones ,leave a bit of offset for sides and height ) close them from toolpathing and display ,make from them surface project on sufrace from this operations ,use surface-contour for letters finishing and shallow for floor finishing .

I did this sort of things a lot .

I would prefer leftover. after roughing and finishing the genral area.
