HAHA my thoughts exactly

I have seen the fuzz. I received a lot of programs and are finding many issues with it. I am also using carbide straight wall, I think I have a few good starting points here. Thank you!

Looking for advice on milling attached part. Specifically the internal dog bone shape; tool continues to break after packing occurs. I fully chain the shape and cut the perimeter. Note the call out, 0.222" is the distance from wall to wall of dog bone shape, tool used is 0.1875". I have used a range of F&S but the packing still occurs. I suspect the heat that is generated from the packing and RPM is causing a weak point. I would like advice on any and all attributes of what I'm doing. Please ask for more details if needed. I am not the originator of the program and would like to improve, I am waiting on an upcut 0.1875" mill. Currently using 15,000 RPM and 75 ipm feed rate. I'm using a 4.0" L, 0.1875" dia. solid carbide router, 2 flute, straight O.

Thank you!

New to Mastercam, new to machining. With Mastercam 2023 I had lost my grid but have sense found it. There problem now is that the 25 X 25 grid seems to have a shading to it that looks like small dots as I zoom in. Is there a setting that's available to change. Any help is appreciated.
