Title:
|
DESIGN TECHNIQUES APPLIED TO THE DEVELOPMENT OF AN ANGULAR MICRO-POSITIONER
|
| |
|
Summary :
|
|
IN ORDER TO ACHIEVE HIGH PERFORMANCE IN ULTRA-PRECISION MACHINE TOOLS, APPROPRIATE CAPABILITY IS REQUIRED FROM MOTION CONTROL AND POSITIONING SYSTEMS WHICH HAVE TO OPERATE AT RESOLUTIONS AND REPEATABILITY IN THE SUB-MICROMETRE RANGE. MODERN DESIGN TECHNIQUES CAN GREATLY ASSIST IN THE DEVELOPMENT AND DESIGN OF SUCH SYSTEMS. IN THIS WORK, SEVERAL DESIGN OPTIONS FOR THE ELEMENTS OF A POSITIONING SYSTEM ARE DISCUSSED AND ANALYSED. THROUGH MODELLING TECHNIQUES, IT IS POSSIBLE TO VERIFY THE STATIC AND DYNAMIC BEHAVIOUR OF THE SYSTEM. A KINEMATICS MODEL OF THE MICRO-TILT STAGE IS PRESENTED IN ORDER TO ESTABLISH A RELATIONSHIP BETWEEN THE DISPLACEMENT OF THE ACTUATORS AND THE FINAL POSITION OF THE STAGE. SIMULATIONS OF THE MODEL ARE PERFORMED SHOWING THAT THE TECHNIQUE APPLIED IS VALID AND THE SYSTEM FULFILS THE REQUIREMENTS FOR ULTRA-PRECISION DESIGN. |
