Abstract
This work presents experimental observations about the influence of the cutting conditions on orthogonal high speed turning in presence of instabilities. Specially, the influences of the machine tool dynamic characteristics, modified by changes of the tool-holder's length, are examined. Following this, in order to excite the system during machining, the cutting conditions were chosen for assuring chatter and segmented chip apparition. The machining tests were carried out on Ti-6Al-4V Titanium alloy samples, using a L₈ fractional Taguchi experiment. This method permitted to identify and compare the cutting conditions' effects on the machining process, minimizing the number of tests.
