Outline of Final Research Achievements

This research subject aimed to form uniform high hardness distribution only at the parts demanded such as the blade edge or rolling element contact parts and high shape accuracy for thin and small parts such as etched blades and miniature guide rails. Moreover, another purpose is to establish the manufacturing method with low environmental burden. Therefore, a new method that achieves high accuracy by performing “dummy irradiation” to offset the thermal deformation during laser hardening was proposed and developed. Moreover, environmental burden reduction effect was shown.

Academic Significance and Societal Importance of the Research Achievements

本研究課題で提案した工法では,従来工法における足かせとなっていた機械的な変形矯正工程が削減されるため,薄物小型部品であっても工作機械1台で機械加工とレーザによる熱処理・形状矯正が実現される新工法であり,独創性が高い.さらに,レーザ焼入れは廃液を伴わないドライプロセスであるため,クリーンな作業環境と大幅な環境負荷の低減が実現され,ものづくりの省エネ化・グリーン化が期待できる.
