APPARATUS AND METHOD TO CUT THREE-DIMENSIONAL AXISYMMETRIC ARTICLE WITH AID OF TEMPLATES

摘要

ABSTRACT The present invention relates to a method and an apparatus to cut three-dimensional axisymmetric article with aid of two same templates. These templates are two dimensional having axisymmetric shape which is same as cross section of an article. Cutting operation is performed by hot wire cutting tool which travels over guide surface of templates. Cutting cycle is performed multiple times and each time workpice is advanced angularly which result in axisymmetric article.
