Abstract
Electrochemical machining (ECM) is a non-traditional method of machining, based on the anodic dissolution of the workpiece, which allows to obtain surfaces of a complex shape (turbine blades, dies and molds, etc.); to produce through and blind holes of different or variable cross-sections, including the curved axis; to remove a defective surface layer from the workpiece after electrical discharge machining or cutting (ECM without shaping) in order to ensure a specified surface roughness; to remove burrs and round sharp edges. Distinguishing features of electrochemical shaping include a narrow interelectrode gap, an electrolyte flow in the space between electrodes, a high localization of dissolution in a specified area of the workpiece, and a high dissolution rate. The efficiency of ECM depends significantly on the shape and size of the electrode-tool, as well as the trajectory and speed of its movement. This article is devoted to the investigation of the combination of kinematic and geometric ECM characteristics. It is shown that the reduction of interelectrode gap under traditional modes leads to a significant increase in the total current and the difficulties of ECM process control. The possibilities of local machining with point and linear electrode-tools are analyzed.
