Abstract
A method of precision electric-discharge machining carried out in apparatus of moderately high precision and stability with an electrode in the form of a wire. The object is a surface as smooth as the surface that can be obtained with the more expensive very high-precision apparatus. The contour of work that has already been roughed out at least once is accordingly exploited as a geometrical reference for at least one finishing cut. The gap is maintained constant by fine adjustments.
