I opened your model, the first observation is that you have only 1 element through the thickness of the plate you want to cut and there is a gap between the plate and the tool.

You can see that in my model, I have 20 elements through the thickness of the part that is being cut and the tool is touching the plate.

If your goal is to make an animation of the cutting, it will be best if you take this geometry and scale it up 1000 times. The reason for this is that the solver calculates a time step based on the dimension of the smallest element. If you check the size of my plate, it is 1000 mm thick! But it solves in about 15 minutes. If my plate was 1 mm thick like your model, it would take 15,000 minutes or 250 hours or 10.4 days to solve.
