Surface generation for material removal after impact of tool

I want to generate a surface with showing material removal due to tool influence on a particular spot.

First I need to generate a flat rectangular surface then I want show the deviation from flatness due to impact of tool.

During polishing process when tool work on a surface it removes material from the surface of the workpiece. I want to generate such kind of matlab based simulation. My material removal function at tool impact spot is MRR = k*p(x,y)*v

Please help me to generate such kind of simulation. I shall be very gateful to you

See ths example

clc,clear

[t,r] = meshgrid(0:10:360,0:0.2:5);
[x,y] = pol2cart(t*pi/180,r);
z = sin(r)./r;
z0 = 1;         % z start coordinate
r0 = 2;         % radius of a tool
for i = 1:9
    x0 = -6;    % x start coordinate
    z0 = z0 - 0.1;  % z increment
    for j = 1:7
        ind = ((x-x0).^2+y.^2 < r0^2) & (z>z0);
        z(ind) = z0;
        surf(x,y,z) 
        x0 = x0 + 1;
        pause(0.5)
    end
end

Thank you so much Darova

[Muhammad Mubashar saeed]

Can you please eleborate it accoding to my Material removal function MRR = k*p(x,y)*v

You may assume values for all of these variables

It will be a great favor from you

Thanks a lot in advance

Can you explain more about removal function? What is it?
