PROBLEM TO BE SOLVED: To manufacture a microchannel cooling passage in a surface of a machine component.SOLUTION: A method for manufacturing a microchannel cooling passage in a surface of a machine component includes: forming an elongated open channel 155 in the surface of the machine component, the open channel comprising a cross-sectional profile having a mouth, a floor and a middle region that is defined therebetween; inserting a corresponding elongated electrode 150 having a directional bias into the channel; and using the electrode as a tooling piece in an electrochemical machining process, widening the middle region of the open channel. 【課題】機械部品の表面にマイクロチャネル冷却通路を製造する。【解決手段】機械部品の表面に長尺開口チャネル１５５を形成するステップであって、開口チャネルは、口部及び床部とその間に画定された中間領域とを有する断面プロファイルを備える、ステップと；方向バイアスを有する対応する長尺電極１５０をチャネル内に挿入するステップと；電解加工プロセスにおいて電極を工具片として使用し、開口チャネルの中間領域を拡張するステップと、により、機械部品の表面にマイクロチャネル冷却通路を製造する。【選択図】図７
