Simulation of material removal rate and data visualization

I have an initial code that calculate the vector velocity of workpiece(Vw) and vector velocity of the tool(Vt) with which I can calculate the material removal rate. we have input parameters which are radius(r1, r2), angles(theta,alpha),angular velocities(Ww, Wt) but in order to calculate the total removal rate we have to calculate the relative velocity at all points with different radius and angles. the angular velocity doesn't change.
I have calculated the relative velocity at one point with some random values but I need from you to calculate the relative velocity at different points and then calculate the total removal rate and make simulation for it with the time.
another thing is to make data visualization for the relative velocity in x-direction and y direction.
