PROBLEM TO BE SOLVED: To form a continuous variable geometry bore hole within a conductive work piece (102).SOLUTION: An electrochemical machining system (100) for machining the conductive work piece (102) includes a drilling tool (112) configured to remove material from the conductive work piece (102). The drilling tool (112) is configured to advance within the conductive work piece (102) along a tool path to form a bore hole (118) that extends through the conductive work piece (102) in two or more dimensions when the material is removed. The system further includes an inspection device (122) configured to determine a position of the drilling tool (112) along the tool path, and a controller (128) configured to communicate with the inspection device (122). The controller (128) is further configured to compare the tool path to a nominal tool path, and determine a position error of the drilling tool (112), the position error defined by a difference between the tool path and the nominal tool path.SELECTED DRAWING: Figure 1 【課題】導電性加工物（１０２）の内部に連続的な可変形態のボアホールを形成する。【解決手段】導電性加工物（１０２）を機械加工するための電解加工システム（１００）は、導電性加工物（１０２）から材料を除去する穴あけ工具（１１２）を含む。穴あけ工具（１１２）は、工具経路に沿って導電性加工物（１０２）の内部を進み、材料が除去される場合に２以上の次元で導電性加工物（１０２）を貫通して延びるボアホール（１１８）を形成する。また、システムは、工具経路に沿った穴あけ工具（１１２）の位置を特定する検査装置（１２２）と、検査装置（１２２）と通信する制御装置（１２８）とを含む。制御装置（１２８）は、工具経路を名目上の工具経路と比較して、工具経路と名目上の工具経路との差によって定まる、穴あけ工具（１１２）の位置誤差を特定する。【選択図】 図１
