Appl. No.:

09/425505

Assignee:

International Classification:

US Classification:

Abstract:

A method of cutting planar material with a controlled cutting machine having a cutting tool with a tool tip includes performing a cutting test on various planar materials with the cutting machine under selected cutting conditions which produce deflection forces on the cutting tool due to the interaction of the cutting tool and materials so as to cause the tool tip to offset and move along deviated or offset cutting paths relative to desired cutting paths, and determining compensating offsets in order to align and coincide the actual cutting paths with the desired cutting paths A schedule of the compensating offsets to align and coincide the actual cutting paths with the desired cutting paths is established as determined by the cutting tests. The schedule is to be repeatedly used thereafter for cutting planar material having cutting conditions associated with the schedule. Planar material is cut thereafter along desired cutting paths by advancing the cutting tool and planar material relative to one another and employing the schedule of compensating offsets to control the actual cutting paths to align and coincide with the desired cutting paths when desired cutting paths and corresponding cutting conditions arise.

Abstract:

A mechanism for delivering a cooling fluid to the interior of a formed bottle has an upper cooling tube assembly secured on a vertical post. The upper cooling tube assembly has a plenum chamber having a bottom wall and at least one vertical cooling tube is mounted on its bottom wall. The cooling tube is mounted on the plenum chamber with a quick release mechanism.
