Development of a numerically controlled hot wire foam cutting machine for wing mould construction

Abstract

The foam mould making for Unmanned Aerial Vehicles should be efficient and accurate to improve research and manufacturing. Hot wire cutting is a widely used method in foam cutting. In hot wire cutting, accuracy and quality of the foam cut mainly depends on the variable cutting parameters which affect the cutting process. To perform a proper cut with required quality the cutting parameters should be set precisely and accurately. This research is done to identify the variations and inter dependency of cutting parameters. It is important to estimate appropriate cutting parameter values before the actual cut. The results of this research aid to improve the hot wire foam cutting by solving the limitations and drawbacks to select best cutting parameters of the Computer Numerically Controlled machine which is in progress.
