Surface machining

[Joels]

Hello, I am going to upload a file called joels1.mcx. I am using Mc X4 and if you could please look at the file as i am trying for the last 2 days to get the surface machining correct. The object is a boss and i need to machine it and that part might be ok but i cant seem to get the flat bottom surface to match up with the boss surface. It seems to leave a little step so i tried diferent cutters (bull nose and radius) to no avail. So now i created the flat surface at the base of the boss but now MC doesnt want to machine it. Can someone please take a look at the program and let me know what i am doing wrong?

Take a look at joels1_crazy.mcx and see if that helps.

Ron,

Thank you for the file. it is better but i was trying to have the cutter machine the boss and then machine the flat surface to ensure there would be no step there. I still see a step. Is this possible? or am i crazy?

[Ron Branch @ Verisurf]

You could try to use surface finish contour. then in the advanced setting tell it to machine the flats. I would use a bull tool in that case and not a ball em. Try the toolpath you got from me with a bull em and change the depth limits to allow it to cut below where I stopped it.

Thank you Ron. I did use the bull end mill before but i didnt use the machine the flats. It looks good now.

 

Thank you for your help.
