1. A high-speed reciprocating wire cutting process in which a wire electrode is transported and precisely guided across a machining area by means of a wire traveling circuit, comprising wherein the cutting process is conducted by repeatedly:
running the wire electrode in a first direction until a first reciprocation position,
stopping and inverting the traveling direction of the wire electrode,
running the wire electrode in a second direction until a second reciprocation position,
stopping and inverting the traveling direction of the wire electrode, wherein
a cutting process interruption sequence is carried out if a cutting process monitoring reveals that the cutting process must be interrupted, whereas the cutting process interruption sequence includes to continue the cutting process until the first or the second wire electrode reciprocation position, and to pause or to stop said cutting process at the wire reciprocation position.
