Riassunto analitico
Thermoforming is the manufacturing process of heating a plastic sheet, forming that to a specific shape in a mold in order to create rigid containers, components for assemblies, and final usable products. The final output of the process is a plastic case wrapping the sample.
This study aims to characterize a thermoforming process in order to investigate how a plastic disk deforms on a mechanical shape and how the output shell wraps the mold. Previous studies have been focused to the characterization on the thermoforming technology, understanding how the change of input parameters, such as temperature, pressure and time, influenced the deformation of the plastic film. In this project, instead, the input parameters are constants but several solids, with different dimensions and geometries, change in order to create a knowledge based on the sample and not on the process.
After the extraction of the underlying solid, the proof is delineated, if necessary, measured, scanned and then analyzed. The analysis is conducted using statistical method like DOE (Design of Experiment) and ANOVA (Analysis of Variances).
The characterization of the process is sudden used to design and produce grippers and actuators suitable for manufacturing industry. Depending on the physical grasping principle, grippers and actuators have been developed with an innovative process, because never thermoforming have never been used to produce these tools. For this reason, a patent, focused on this innovative manufacturing process of production of grippers and actuators, is written and filed.
Finally, to transfer the knowledge acquired on a productive field, collaborating with ERREQUADRO s.r.l., a Pisan firm supports products innovation, the thesis includes a project developed to optimize the work cycle of a humanoid robot, re-engineering the process and designing a new gripper.
