Recently, self-propelled rotary tools have garnered significant attention due to their potential to enhance machining productivity. The fundamental principle behind these tools involves the utilization of a circular cutting instrument that continually rotates around its axis during machining. This rotational motion facilitates a more effective distribution of thermomechanical stresses along the cutting edge. Existing literature reveals promising outcomes regarding the wear performance of these tools. However, their optimization in terms of development and parameterization remains suboptimal due to insufficient experimental data and limited analysis of thermomechanical phenomena. To comprehend the underlying phenomenology governing the operation of these tools, it is crucial to identify the relationship between the rotation speed of the insert and various cutting and engagement parameters, as well as the insert's inclination and geometry. This study relies on an experimental turning apparatus capable of non-intrusively monitoring the continuous rotation of the insert. By employing specialized image analysis techniques, the registered images of the insert during machining are examined in detail. Subsequent processing of these images, while eliminating the interference caused by disruptive chips, enables the determination of the insert's rotation speed. [ABSTRACT FROM AUTHOR] |
