Question: Develop a program in python or Matlab for generating tool path and machine a free form surface with surface finish.
a) Define a free-form surface of minimum 4 x 4 matrix.
b) Develop a Bezier surface from grind of pts. (option to change control points should be provided)for eg:input: Enter ‘n' matrix4(enter the matrix)Enter (i) Do you want to change control points?Enter(2) No needIf(1) enter:- P131 2 3If(2)Provide plot (3 - D)If(2)Provide plot( 3 - D)
c) Develop a zig - zag tool path to machine the surface
d) The incremental surface between one pass to other has to be calculated based on desired surface finish. Consider, scallop height = surface finish
e) Step forward in a pass has to be calculated based on chordal error so, that accuracy can be achieved.
f) Provide a CNC program for the generated tool path, and point it in a text file.
g) Mention tools required to machine the surface.
