電気電子工学科(EL 学科)の平成 30 年度における新たな取り組みとして、プロジェクトデザイン入門(実験)(以下、PD 入門(実験))の検討を行い、前学期に実施した。ここではその内容について報告する。専門科目との接続を重視した PD 入門(実験)のカリキュラムにおける位置付けを示すとともに、EL 学科の実験科目との関係について説明している。これまでのいきさつとして電気系ワーキングの取り組みについても説明する。PD 入門(実験)の学習支援計画書に盛り込んだ内容を示し、6つのテーマ、運営方法などを紹介する。実施結果の検証として受講学生および TA 学生に対するアンケート調査を行い、その結果について検討している。さらに過去3年間の電気回路Ⅰの中間試験結果について比較検討し、PD 入門(実験)と並行して開講された電気回路Ⅰの理解度について考察する。;We have developed practical education of the introduction to project design (PD introduction (experiment)) as a new approach of the department of electrical and electronic engineering in this academic year. This paper reports the detail of the development. Position of the curriculum of PD introduction (experiment) is shown for orientation of major subjects. Relationship with the major experiment subjects is also explained. As the past efforts, related activities in our department are described. Contents of the developed syllabus are explained, and then it shows six themes and steering methods. As a verification of the implementation results, we conducted a questionnaire survey on students attending and TA students. The summary results and graphs are shown. In addition, based on the results of the intermediate test of Electric Circuit I in the past three years, understanding degree of students with respect to PD introduction (experiment) is discussed.

Recently, a titanium alloy has been as biomaterials that have stable mechanical property and superior biocompatibility. But the titanium alloy generally has higher young’s modulus in comparison with cortical bone, then bone resorption was occurred by stress shielding. For this reason β-type titanium alloy exhibiting super-elasticity and super-plasticity was developed. This alloy has high tensile stress and low young’s modulus too. However, the characteristics of this alloy is lost by severe heat environment and external force. Therefore, there is possibility that the advantageous characteristics may be lost during cutting. In this study, the effect of cutting temperature and cutting force on the affected layer was investigated by milling with small ball end mill tool in order to decrease the affected layer by cutting process. At the cutting speed of 16.0m/s, the thickness of the affected layer exceeded 2.5μm because of increasing of cutting temperature that approached to the neighborhood of transition temperature of this alloy. On the other hand, the affected layer was observed for the cutting condition of high cutting force by increasing feed rate of a tooth, depth of cut and pick feed, the thickness of the affected layer was 0.7μm .So, the affected layer was dominant by the influence of cutting temperature. To decreasing affected layer, the cutting temperature is able to decrease to decreasing feed rate of a tooth or depth of cut.
