Obiettivo del progetto (Objective)
'PoPJIM identifies critical performance limiting problems in machine tool design and use. The project idea is based on two crucial innovative solutions: i) replacing conventional machine tool structural joint interfaces by a self configuring and optimising mechatronic module called Joint Interface Module, JIM, made of functional materials and ii) a wireless network consisting of these modules and a machining process proxy to enable adaptive control and plug and produce capability to the JIMs. JIMs are designed to adapt the dynamic behaviour of a machine-tool during its interaction with the cutting process. Traditionally dynamic instability in a machining process is controlled by tuning the process parameters to match with the inherent dynamic characteristics of the machine tool structure which often results in lowering the rates of production. The novelty of the JIM concept is instead of changing the process parameters; dynamic stiffness of the machine tool is controlled to maintain the process stability. The Distributed Wireless Configuration and Control Network enables plug and produce capability and decentralised control of JIMs through a wireless communication network. This development is essential for achieving modularity and plug and produce capability for JIM-based machine tools. Controlled design of JIMs allows the dynamic behaviour of the machine tool to be predictable with more accuracy. The mechatronic design of the JIM includes an integrated control system and embedded intelligence which enable to be self-adaptive for optimising the dynamic stiffness within its design range during a machining process. The results of research and development work will be demonstrated in industrial context and there is a dissemination and exploitation activity to reach out potential stakeholders.'
Introduzione (Teaser)
EU-funded scientists are seeking to increase precision and product quality in manufacturing by cutting the 'chatter' in machining.
Descrizione progetto (Article)
Current machine tool design criteria mainly focus on lightweight and dynamically flexible parts for high-speed and more efficient machining. Unfortunately, this often leads to machines being less resistant to vibrations (so-called chatter). Control over machine chatter is critical to quality and performance and dynamical instability of the cutting process needs to be addressed.
Traditionally, machine tool dynamical instability has been controlled a priori by setting the process parameters based on the machine inherent dynamic characteristics (essentially factory specifications). A much more effective solution would be adaptive control of process parameters according to the actual real-time dynamics of the cutting machine.
In the EU-funded project 'Plug and produce joint interface modules' (http://www.popjim.com/ (POPJIM)) scientists are working on replacing conventional machine tool structural joint interfaces with a self-configuring and self-optimising mechatronic module. Known as joint interface module (JIM), it includes an integrated control system with embedded intelligence to control dynamic stiffness of the machine tool. This eliminates the need for an operator to change process parameters in response to dynamical instability.
Connecting multiple JIMs in a distributed wireless control network (DWCN) will maintain overall machine stability and provide so-called 'plug and produce' capability. The configuration software will recognise new JIMs that have been connected or removed and control the system accordingly.
To date, the JIM control system with sensing and JIM actuation have been developed. Furthermore, scientists have set up the DWCN. This included developing wireless nodes for the vibration sensors, the real-time system monitoring unit and the configuration support platform.
A self-tunable JIM without the wireless communication has been installed and demonstrated in one of the partners' site.POPJIM is expected to enable high-precision machining of complex parts with zero defects, which is the goal of the EU factories of the future.
