What is Mechatronic System Design and Construction of a CNC Machine for Cutting Styrofoam Parts for RC Planes about?

## Abstract Flying radio controlled, RC, planes has become both a sport and a form of entertainment that attracts an increasing number of practitioners worldwide. RC plane hobbyists design and build reduced-scale airplanes, unmanned aircrafts or replicas of existing full-scale ones, and fly them as often as possible to develop the necessary skills to go from basic flights to complex maneuvers and acrobatics and to race against other planes. Unfortunately, many practice flights do not go as planned and end with physical damage to the aircrafts. Companies dedicated to the production and marketing of RC planes require Computerized Numerical Controlled, CNC, machines to cut different parts for these model aircrafts due to their geometrical complexity, such as the case of the wings. Airplane wings must be light, strong and at the same time they have a tridimensional shape which is difficult to obtain by means of conventional manufacturing processes such as milling. Styrofoam is a convenient material for the fabrication of RC plane wings. The most common way to cut Styrofoam parts is by means of a taut hot wire. In order to achieve the complex shape of the wing, starting with a block of
