Characterising the behaviour of workpieces under the effect of tangential cutting force during NC turning
Résumé
Turning slender workpieces usually means a tailstock centre has to be used to in order to achieve geometric tolerances for cylindricality. Indeed, tight tolerances mean the grinding phase can be performed quicker or even rendered superfluous. To limit use of the tailstock centre, that limits tool access when producing slender workpieces using turning, knowledge of the spindle-chuck-workpiece assembly's behaviour is essential. It is proposed to characterise this assembly's behaviour under the action of machining loads in order to introduce a method that in some cases will dispense with the need to use the tailstock centre while keeping the geometric quality of the machined workpiece.
