Abstract

The question of how to control a robotic welding torch to trace the joint between two cylindrical pipes can be reduced to a problem in algebra. Maple can be utilised to derive the parametric equations describing the curve of intersection between the two cylinders, and then to explore the solution graphically for various physical parameters. This problem can serve as an excellent introduction to the use of Maple for simplifying and solving systems of equations, and offers several straightforward extensions that increase its applicability to more advanced mathematics courses.
