MACH21 Mach21 in EMO 2003 Mach21 in EMO 2003 21-28/10/2003 Multipurpose and cross-sectorial modernisation of manufacturing processes through parallel kinematics
MACH21 Mach21 in EMO 2003 Requirements for the new machines: –Customer and process focused solutions. –High feed rates (machining and traverse movements). –High accelerations. –High stiffness. –Good dynamic behaviour (high Jerk and kv values). –Low cost (high productivity). –Reliability. –Process specific precision. …¿is this possible with conventional solutions? Not in a sustainable way. Need for breakthrough. JUSTIFICATION
MACH21 Mach21 in EMO 2003 MACH21: an answer to the European challenges: –modernise the manufacturing processes of the industry. –standardise as much as possible both the mechanical and electronic (numeric control, measuring devices) components –reconfiguration and reuse of manufacturing systems. –minimising the material consumption –Contribute to speeding up industry's adjustment to structural changes –safety in the machinery. –Educational aspects JUSTIFICATION: the European perspective
MACH21 Mach21 in EMO 2003 What is a parallel kinematics machine (PKM)? Traditional (serial) machines: each axis or carriage carries the subsequent axis to provide the desired tool movements Parallel kinematic machines (PKMs): the tool movements are achieved via coordinated traslations of several axis arranged in parallel. No longer a carriage transports another one.

MACH21 objectives The project MACH21 has meant an holistic or overall approach to PKMs in order to try to solve or minimize the most important generic problems that affected this technology at the beginning of the project, through the whole life cycle. This way the project bets for a modernisation of the production means and brings nearer the implementation phase of the parallel kinematics production technology in the industrial companies shop floors by improving the PKMs performances in the areas of accuracy, dynamics and flexibility.
