A machining system for machining a workpiece to form one or more conduits, the machining system comprising: a machine tool; a plurality of cutting tools configured to machine the workpiece to form the one or more conduits, the plurality of tools comprising an electrode disposed on the machine tool; a CNC controller configured to control the machine tool to move the respective cutting tools relative to the workpiece and identify position and dimensions of each of the one or more conduits to be formed in the workpiece, each of the one or more conduits comprising at least two target zones; a process controller configured to monitor gap status between the electrode and the workpiece, and communicate with the CNC controller to control the machine tool; and an electrolyte supply configured to pass an electrolyte between the workpiece and the respective cutting tools; a power supply configured to energize the electrode and the workpiece to opposite electrical polarities and pass an electric current between the electrode and the workpiece to remove materials from a first target zone to define a first cavity within the first target zone of the at least two target zones of each of the one or more conduits to be formed; and a conventional cutting tool exchangeably disposed on the machine tool configured to perform a first mechanical machining step on the first cavity within the first target zone of each of the one or more conduits to be formed;wherein the machine tool, the electrode, the CNC controller, the power supply, the process controller and the electrolyte supply are configured to cooperate to function as an electroerosion machining device; and the machine tool, the CNC controller, the conventional cutting tool and the electrolyte supply are configured to cooperate to function as a conventional machining device; and wherein the machining system is configured to function alternately as the electroerosion machining device and the conventional machining device; wherein the power supply is further configured to pass the electric current between the electrode and the workpiece to remove materials from a second target zone to define a second cavity within the second target zone of the at least two target zones of each of the one or more conduits to be formed, and wherein the mechanical cutting tool is further configured to perfom a second mechanical machining step on the second cavity within the second target zone of each of the one or more conduits to be formed, and wherein the first cavity and the second cavity are defined within the at least two respective target zones along opposite directions. a machine tool;
