Hi,
I have a small part that has a chamfer in it that is roughly 4.25mm in length. I did the toolpath, profile with a ball nose end mill and when it completes, the surface is really bad on the part. I figured if I make really small movements in the z axis it would leave a nice machined surface. I'm using a 5/32" 4 flute ball nose end mill, moving in the z direction at 0.15mm each step and have a cut feed of 150mm per minute. The cutter was brand new so I don't think that was the problem. I first rough the path with a 5/32" square end mill and I leave 0.25mm material for the ball nose operation.
Is there anything I can do in the cut path that will leave a better finish on the part? I'm trying to polish the part to a mirror finish and with all these lines in the part, it takes for ever for the tumblers to polish it.
Thanks in advance for any insight.
Have a great day,
Craig
