Hello
This looks like a machine/fixture problem. What type of machine do you use? Are the axis in good conditions?
Is the workpart/tool proper clamped?
What type of material do you cut?

Maybe for a better surface finish you could copy your operation and give one operation (rough) some bottom stock. And then run the (finish) operation with "0" stock.

Best regards

I have see this when the material is not flat when your machiing.  The material will lift up when the tool / machine stops at the end of the cut/stepover.  Definitaly a process issue, not the tool path.  Creating a 2nd pass to finish the floor may help.  If the stock is not flat the problem will persist.
