PROCESS FOR FABRICATING WORK-PIECES WITH POLYGONAL INNER AND/OR OUTER PROFILE AND PLANTS FOR IMPLEMENTING SAID PROCESS

摘要

Process for fabricating work-pieces with polygonal inner and/or outer profile, preferably by removal machining, wherein the work-piece pivots about a fixed axis (4) at constant speed while the tool (5) defines a closed loop path, wherein the rotation speed of the work piece and the rotation speed of the tool (5) on its path (6) are interdependent and wherein the tool (5) bites on the work-piece throughout its path, wherein the tool follows a closed path (6) differing from a circle and which is traversed by the tool (5) with a displacement speed varying in the course of one path by virtue of a predetermined displacement law, and wherein the path (6) is excentric with respect to the rotation axis (4) of the work piece and surrounds the latter.
