Form Error Prediction in Robotic Assisted Milling

Structural Potting of Large Aeronautic Honeycomb Panels: End-Effector Design and Test for Automated Manufacturing

“…The specific static and dynamic characteristics of robotic arms require dedicated planing of machining operations to improve accuracy by using a multi-axis compensation mechanism [ 14 ] and position control depending on force [ 15 ], kinematic analysis of the arm [ 16 , 17 ], or the effective stiffness of the arm [ 18 ]. Alternatively, a dedicated design of robotic arm for machining can improve the stiffness and dynamic properties, as well as the costs [ 19 ], and specific robotic designs [ 20 , 21 ] have been analysed to better understand their dynamic responses.…”

Investigation of an Actively Controlled Robot Arm for Vibration Suppression in Milling

“…Also, in order to increase the productivity of the process, dynamic stiffness and damping ratio of the workpiece can be improved. There are many techniques with fixed supports [2] and mobile supports [3] to avoid chatter but an interesting current approach is to use robotic systems as part of the machining system. Robots can be used to directly machine components, yet they tend to exhibit very low stiffness which exacerbates excessive vibration.…”

Útiles de automatización en procesos de fabricación de piezas complejas de CFRP para la industria aeronáutica

“…Las características estáticas y dinámicas específicas de los brazos robóticos requieren una planificación específica de las operaciones de mecanizado para mejorar la precisión mediante el uso de un mecanismo de compensación multi-eje [14], control de posición en función de la fuerza [15], el análisis cinemático del brazo [16][17], o la rigidez efectiva del brazo [18]. Alternativamente, un diseño específico de un brazo robótico para el mecanizado puede mejorar la rigidez y las propiedades dinámicas, así como los costes [19].…”
