At EMO 2019, from September 16 to 21, 2019 in Hanover (Germany), PCI SCEMM, machine tool builder and supplier of turnkey manufacturing lines, will lead the way in intelligent machining with e-Spindle.
Developed jointly with Amvalor, Arts et Métiers' subsidiary dedicated to technology transfer and the valorization of its research results, and Cetim, this unique electrospindle incorporates all the equipment needed to monitor the cutting process as closely as possible and act in real time. The integrated technology, enabling efficient management of sensors and actuators in a rotating reference frame, is the result of joint work on intelligent machining by Cetim and Lispen (Laboratoire d'ingénierie des systèmes physiques et numériques), Arts et Métiers campus in Aix-en-Provence (Intelus project, 2014-2017).
The aim is to increase productivity, by optimizing tool life, and quality, by instantly correcting processes. Such a device also makes it possible to secure very high value-added machining processes, or to implement adaptive processes, capable of modifying operating parameters in real time.
Three intelligent machining applications will be presented at the show:
A tool holder for monitoring the cutting process (forces, vibrations, cutting fluid pressure),
An adaptive vibratory drilling toolholder, controlled by force threshold levels
A honing tool holder, incorporating a "real-time" measurement of the workpiece diameter, used to control the position of the active parts (abrasive stones).
According to its designers, e-Spindle paves the way for many other intelligent, connected machining applications.
