Title:
IMPROVED COLLET AND METHOD FOR OPTIMIZING GRIPPING ACTION THEREOF
Document Type and Number:
WIPO Patent Application WO/1995/018690
Kind Code:
A1
Abstract:
The present invention relates to a method and process for manufacturing an improved machine tool collet (10). The invention further relates to an improved machine tool collet (10) having design parameters optimized to maximize the gripping strength of the collet (10). The collet (10) is of the type having a plurality of gripping jaws (16) spaced around a common longitudinal axis (18) with resilient material (12) between the gripping jaws (16). The method includes calculating the total torque (TN) generated on a bar passing through the collet (10) for a given collet configuration having predetermined design parameters. At least one of the design parameters of the collet (10) is varied and the total torque (TN) generated is recalculated until the total torque (TN) reaches a maximum value for the given collet configuration. In this manner, at least one design parameter can be varied and optimized for maximizing the gripping strength of the collet (10).
