How to Develop a program calculating the spiral in/out (contour) tool path to cut a 3D (may be extrude, sweep, revolved, spline) surface.

I have a homework in my master's class, I tried to do it using Mathcad but couldn't. So I request for your help coding it using Matlab. I attached the documents, and waiting for help.

Istanbul Technical University MAK 536E Advanced Computer Aided Design

MAK 536E Advanced CAD Course Homework 2 Due date: April 15, 2014 Tuesday 9:00

Problem: Develop a program calculating the spiral in/out (contour) tool path to cut a 3D (may be extrude, sweep, revolved, spline) surface. Students should write their own program file and, use different sizes and positions. First, you must define the control points of the 3D surface. Student are free to use any of the calculation softwares like MathCad, MatLab, Maple, Mathematica, Excel, Java, Pascal, C and Basic programs. The results should be drawn by software. Homework will be submitted yo www.ninova.itu.edu.tr web site. Printed hardcopy is not required. “18_B-SPLINESurface.mcd”, “22_sweptsurface.mcd”, “24_CoonSurfaceI.mcd” zig-zag tool path sample files from the course notes, may be helpful to start writing your program. Add the offset distance of tool radius to your path.

That you have homework is good, for you. But we don't do your homework for you, as that will result only in your getting a grade that you don't deserve, while not learning anything in the process. Homework is there to help you, by actually doing it yourself. Making that effort is what helps you.

So try it. Make a start. When you run into problems, you may gain more sympathy if you show you have made an effort.
