Electromechanical Machining.
Abstract
The purpose of this investigation was to determine the feasibility of using a new metal cutting process called electromechanical machining in which metal is cut by direct contact of the tool with an electrochemically polarized workpiece. In this process, electrochemical polarization of the workpiece effectively controls the coefficient of friction, between the tool and the workpiece, and the rate of work hardening. Thermoelectric compensation was also used to reduce cutting tool wear while simultaneously investigating electromechanical machining. Electromechanical machining was used in laboratory experiments with polycrystalline nickel and Hastelloy X workpieces. The workpieces were totally submerged in an electrolyte, and a 7-inch shaper was instrumented with strain gages so that forces required in cutting at various electrode potentials could be determined from the tool deflection.
