“…The research was done on simple geometry parts such as a cantilever plate. Diez et al [133] used this technology to compensate the deformations of the part, improving final dimensional error. Rashid and Nicolescu [134] proposed an active control of workpiece vibrations in milling through piezo-actuators embedded in workholding systems.…”

Thin-wall parts are common in the aeronautical sector. However, their machining presents serious challenges such as vibrations and part deflections. To deal with these challenges, different approaches have been followed in recent years. This work presents the state of the art of thin-wall light-alloy machining, analyzing the problems related to each type of thin-wall parts, exposing the causes of both instability and deformation through analytical models, summarizing the computational techniques used, and presenting the solutions proposed by different authors from an industrial point of view. Finally, some further research lines are proposed.

“…Because of their application in aerospace industry, military, energy and shipbuilding industry, face high requirements with regard to their surface quality parameters owing to the significance of these parameters for the operational reliability of such parts [3,8,13]. Their machining is more complex than that of rigid shafts [6,14]. In order to comply with the requirements, new solutions must therefore be implemented, already at the stage of designing technologies for producing these parts, e.g.…”

In the process of machining of shafts with low rigidity it is difficult to achieve the required parameters of accuracy of form and dimensions and of surface quality. Under specific conditions, low inherent rigidity and the relatively low shaft rigidity, compared to the rigid assemblies of the machine tool, cause vibrations. The paper presents a 7-level hierarchical mathematical model of the system of longitudinal turning and a mathematical model of the dynamic system of machining of shafts with low rigidity in the elastic-deformable state, taking factors interfering with and destabilising the process of shaft machining into account. For the purpose of validation of the models, a study was conducted on the conformance of the dynamic characteristics of the mathematical model with the actual object. The study was realized on specially designed experimental workstation for the study of characteristics of the dynamic system of turning of elastic-deformable shafts with low rigidity. The experiment demonstrated a high conformance of the dynamic characteristics of the mathematical model with the actual object.

“…Trabajos posteriores establecen una expresión para el espesor de viruta en que el cálculo del espesor de viruta en cada instante es sustituido por un cálculo centrado en el ángulo proyectado (H. Pérez 2012; Diez, H. Pérez et al 2015) que incorpora una importante ventaja desde el punto de vista del cálculo. Este valor se representa por el espesor medio de viruta que se obtiene mediante la Ecuación 2.17.h…”

“…La dinámica ha sido considerada en modelos para operaciones de fresado de piezas de pared delgada (Diez, Leal-Muñoz et al 2017;Diez, H. Pérez et al 2015), en este caso se busca establecer una fuerza de corte ajustada para determinar la deformación que se producirá en la pieza por efecto de las fuerzas de corte. El sistema pieza herramienta se modela en la mayoría de las investigaciones como un sistema de dos grados de libertad (Altintas, Stepan et al 2008;Moradi et al 2013), como se muestra en la Figura 2.8.…”

“…En la Figura 3.1 se muestran los principales ángulos que definen el proceso, junto con el ancho y la profundidad de corte (a e , a p ). La evaluación de la influencia de los parámetros de corte se ha hecho basándose en un modelo de la presión específica de corte (Diez, H. Pérez et al 2015;H. Pérez et al 2013) que ha mostrado una elevada precisión en la predicción de la magnitud de la fuerza.…”
