Mathematical Analysis of the Process Forces Effect on Collet Chuck Holders

Chuck holders are widely used for jobs with high precision. A chuck holder consists of a nut tapered surface and thin-slotted clamping sleeve typically made hardened steel named collet. are, essentially, wedge mechanisms. In this paper, we investigated the reactions strains due to forces during chip removal process in contact elements or jaws collet by means mathematical analysis. Deflections arise influence from precision workpieces. The cutting cause an axial force, radial torsional moment, bending moment on collet, and, consequently, displacements inclinations system caused. Therefore, proposed analytical models based elasticity theories. model determining deflections force was developed implemented using MATLAB. results showed that variation rotation mainly depends stiffness workpiece. indicated should be vulcanized minimize deformations affect final product. depend strongly clearances, angle,
