オープンソース3Dモデラーとレーザー加工機による機械実習教材の開発

抄録

Recently, PBL (Problem/Program Based Learning) is very important subject in university and college education. In the PBL subject with manufacturing components, computer numerical control (CNC) machine tools is useful than general-purpose machine tools. In this study, we developed a procedure manual of operating CO₂ laser cutting/engraving machine with open source 3D modeler for manufacturing activity basics in PBL subject. On the other hand, CNC machine such as laser cutting/engraving machine and topology optimization have a high affinity for each other. Accordingly, we showed a procedure manual of open ring pull can opener gadget topology optimization with base-model for the college of technology second grade students, who not yet learned Strength of Materials and Computer Aided Engineering (CAE) / Finite Element Analysis (FEA).
