Abstract
Some of the most important devices in machine tools are collet chucks, which are often used in turning, milling, grinding and inspection. Researchers have focused on tool clamping devices based on spring collets, tool collet chucks that must achieve high rotational speeds while maintaining good rotational accuracy but none of them have presented an analytical model to determinate the initial static clamping force in automatic collet chuck holders, widely used in turning machines, taking into account the effect of the main cutting force. This paper first describes analytically the clamping-unclamping principle of the automatic collet chuck holders in its initial static state. Second, it presents the finite element method, static analysis, that were conducted to check this principle. The results will confirm the linear behavior of the two models with excellent levels of correlation.
