Project Context and Objectives:
The FlexiTool project focuses on development of a digitally controlled variable geometry tooling and implantation market for manufacture of 3D architectural panels in high performance composites for the construction industry. The main advantageous features of FlexiTool prototype are rapid, universal, sustainable and cost-effective with high reconfigurablity compared with present thermoforming using dedicated solid mould or fixed hard dies. It is the aim of FlexiTool to empower digitally flexible tooling technology with a clear focus on immediate industrial exploitation in construction and building, and to drive the development of reconfigurable tooling for the benefit of SME participants leading to new processes. There are no such product of mouldless thermoforming tooling available on globe market. FlexiTool will play a key role in realising the full potential of reconfigurable tooling by combining innovative multi-point forming (MPF) technology with robotic control technology.

The industrial and scientific breakthrough objectives of the project are:
(1) Fundamental exploitation of FlexiTool machine using multi-point forming methodology for manufacturing curved cladding and facade composite panels.
This will lead to realise rapid mouldless thermoforming of thermoplastic cladding and facade panels.
(2) Solution of the key technological problems of FlexiTool machine.
This will lead to develop FlexiTool manufacturing cell compositing multiple active actuators to replace the traditional fixed moulds.
(3) Build of the integrated the integrated computer software interface and robotic control devices.
This will lead to the digital optimisation of deformation and the automatic controlling of a FlexiTool machine.
(4) Development, demonstration and implantation of FlexiTool manufacturing cell.
This will lead to reduce tooling costs by 70%, cut set-up time by 60% and eliminate the need for tooling storage significantly and the quick tooling adaptation to architecture design or changes.

The main objective of the present project is to develop and apply the Multi-Point Themmo-Forming Tooling (MPPTFT) technologies in European construction industries. It is the aim of FlexiTool to empower reconfigurable MPF tooling technology with a clear focus on ndustrial applications in architectural and civil engineering structures for the benefit of three European ME participants (ADA, IOTA and ROBOTNIK).

Project Results:
The FlexiTool project intends to research and develop reconfigurable multi-point thermoforming tooling. Currently, a trend of digital manufacturing implementation in construction and civil engineering is to develop advanced fabrication techniques and novel equipments for building fabrication and assembly, which are flexible, cost-effective, affordable, economical and reusable. The project has an ambition of augmenting competitive capacity of European SME industries in global market of contemporary building and rapid manufacturing by promoting the advanced multi-point thermo-forming technologies.

With multi-point forming (MPF) technique, traditional mould tools would be replaced by adjustable punch matrix, called Mould-less forming tooling. The position of each punch can be numerically controlled independently. While all the punches are adjusted to their desired height, the tips of the punches approximate a discrete surface of three-dimensional (3D) tooling shape. The MPF tooling would be used in the thermoforming of thermoplastic sheet parts to take place of fixed moulds. During the thermoforming, the punch of matrix is mounted on the vacuum press. Due to its easy reconfiguration and rapid flexibility, it is a universal tool for manufacturing 3D panels. The obvious advantage over conventional tooling is the reduction in time and cost of design, fabrication, storage and changes of dedicated mould tool.

The FlexiTool prototype of Multi-Point ThermoForming Tooling (MPTFPT) system comprises the hardware and software. The hardware includes the mechanical mechanism and low & high level computer control system. The software includes CAD/CAE/CAT platform and low & high level control software. The CAD software will be used to model the multi-point thermoforming process with panel data and to calculate the position of each punch. The CAE software will be used to simulate the multi-point thermoforming process with data output by CAD software and analyze the deformation and the stress distribution. The CAT software will be use to calibrate the position of each punch for operation of MPTFT.

The Control System for MPTFT will consist of a sub-system composed by:
(i). A control computer unit, dedicated to the operator interface and to the generation of the control signals for the motor driver.
(ii). A driver assembly unit composed by the set of motor driver to be controlled.

The Control Computer Unit shall be equipped with an Ethernet LAN connection for an easy exchange of the PUN files generated by CAD/CAE software. PUN file generated by CAD component, mainly contains all the heights at which each punch has to be regulated to with the regulation that have to be applied to the multi-point thermoforming tooling in order to manufacture specific panels. The PUN files shall contain all the setting required for the setup of the punch groups. The PUN file contains also data related to the physical layout of element groups and of their punches. Such data are not strictly related to the High-Level Control System, but since the program is the main interface to the operator in the workshop, such information are useful to assemble/verify the configuration of the flexible modular group layout.
The Driver Assembly Unit shall be mainly composed by the driver units. Control signal will be bi-directionally exchanged with the CCU, including:
(i). Motor motion signals (pulses)
(ii). Motor direction/rotation command
(iii). Movement stop switch

The high-level control unit is a software component developed to apply the data generated by the FlexiTool CAD application to the tooling mechatronics via the low-level driver. Data are computed to properly support panel of a defined shape.The high-level control unit implements the following functions, all accessible through the application main menu in Computer Aided Translation (CAT) software.
(i) The “Tooling Control” function allows the transfer of all the settings of the PUN file to the corresponding actuated punches (“Set all forming elements...”) and to perform additional control on the forming elements.
(ii) The height of each punch element can be checked and modified manually, and also each punch can be adjusted manually if necessary. If there is no error, the height of all punches is adjusted by the computer control unit through field bus automatically.

Potential Impact:
The main objective of FlexiTool is the development and application of digitally controlled variable geometry tooling using reconfigurable MPF methodology to develop a commercialized machine for manufacturing free-form (3D compound curved) panels for architectural and civil engineering structures in the building and construction industry. The project will develop a unique FlexiTool manufacturing cell, at the heart of which is a large modular robotic MPF machine to provide an alternative to traditional fixed tooling for the manufacture of thermoplastic and composite cladding and facade panels. The FlexiTool machine is a computer controlled machine which changes its own surface geometry to conform to the 3D CAD data supplied by the architect and the material requirements. FlexiTool manufacturing cell will enable rapid, reliable and cost-effective manufacturing of architectural panels in building with digitally controlled variable geometry tooling. Today there is no such manufacturing system of this type available on the market.

The FlexiTool project is centred on the great economic interest of SME participants. The cost benefits of FlexiTool derive from making the current fixed tooling practice redundant, the elimination of the time consuming, costly manufacture and waste of sacrificial solid moulds. These costs currently represent a major proportion of any production process in mould thermoforming and die casting and would be completely eliminated by the adoption of the FlexiTool machine.The FlexiTool project aims at strengthening the research capabilities, competitiveness and innovation capacity of the SME participants in the field of architectural façade fabrication, building construction and civil engineering and at contributing to an overall continued improvement in their industrial competitiveness across the European Union. The project will provide contributions to impacts on SME developments of at the European level. The underlying economic premise of the FlexiTool project is that an investment in a sophisticated and capital intensive machine proves to be significantly more cost effective, and environmentally sound, over time than multi-million Euros worth of discarded single-use fixed tooling over the same period.

FlexiTool consortium has organised various activities to raise public participation and awareness:
(i). Newsletter articles have been distributed widely;
(ii). Three public events have be organised to raise public awareness and obtain technical feedback(Steel-Forum 2010, AERODAYS2011, Metal Forming course at Oulu University);
(iii) Two FlexiTool websites (i.e., have established for the promotion of multi-point tooling technology;
(iv). Three participants have introduce their involvement in the project to their own websites (i.e.;;;
