nYour image shows the Directional Deformation of the Body that has a maximum value of 10 mm. I suggested you select a Vertex at the tip of the tool, right on the Y axis. Did you do that? That vertex will have a zero output before cutting begins, and a very small output while cutting. Is that not sufficient for your needs?nTry putting a Revolute Joint to Ground and scope it to the back circular face of the tool. That will put a Coordinate System on the Tool that rotates with the tool. Maybe you can Probe Joint Displacement under the Solution branch.n
