How to get a good surface finish using 3D finishing tool path?

[utsav]

I am trying to put a finishing tool path on an angled slope using Raster but I can't seem to get a good surface finish. I am using the minimum stepover and letting the software automatically choose the scallop height. Can someone tell me what else I can try to get a good surface finish?

Not nearly enough information....

Tool, Tool size, stepover value,  material, is the setup rigid enough, speeds & feeds

The important thing is the effective chip load. The calculated chip load will likely be too light due to chip thinning.

It is sometimes a little scary how fast you need to go.

As JP says, more info will get a more accurate response.
