First let me say I do not see a lot of 3D surfacing job and do not have a lot of experience with it. Over the weekend I took the time to play around with 3D surfacing.
While the finish is ok, it could be better
Machines Haas vf2ss 2019
Material 6061
Operations
Rough with 1/2” to get the step stair look leaving 0.020 radial and axially
Came in with roughing parallel tool path 3/8 ball nose. Step over is 0.030 leaving 0.005 axially. IPM 150, 10k rpm, 0.005IPT
Finishing is same ball nose 0.005 doc step over is 0.005 (left part in the below picture, 0.010 step over on the right. 0.010 i want to say was feed rate of 175ipm) 225ipm. I can’t remember rpm but the effective chip thickness is 0.0006. 8,000 rpm, 225IPM.
The tool was moving back and forth in XZ zigzagging. The surface is smooth, if you run your finger nail over the surface fast enough you can hear it make a ripple type sound. Sorry if I’m explaining that wrong.
I’m thinking why the surface finish looks the way it does is from chip thickness being so low due to chip thinning? Thought? Thanks in advance
The 3D chamfer came out great
**Finish ball end mill** Notice the actual chip thickness is 0.0007 I went faster to make a better chip.
