Abstract
Official abstract text for this publication.
A relationship between a weight of a reel supported by a column of a wire electric discharge machine when a wire electrode is wound around the reel, and an amount of slanting of the wire electrode when the wire electrode extended between an upper wire guide and a lower wire guide becomes slanted as a result of the column being deformed by the weight of the reel is stored. The weight of the reel is determined during electric discharge machining, and the amount of slanting of the extended wire electrode is determined from the weight of the reel. A compensation amount for the slanting of the wire electrode is determined from the amount of slanting, and the slanting of the wire electrode is compensated by the compensation amount.
First claim
Opening claim text (preview).
The invention claimed is: 1. A wire electric discharge machine including a reel which is supported by a column and around which a wire electrode is wound, and an upper wire guide and a lower wire guide which support the wire electrode that is drawn out from the reel, and carrying out electric discharge machining of a workpiece fixed on a table by relatively moving the wire electrode extended between the upper wire guide and the lower wire guide with respect to the workpiece accordi…
