Project Description
X-Y tables
X-Y tables are used to perform wiring and placement tasks within a μ-range in the field of microprocessor manufacture. The X-Y movements must occur at the highest possible speed with the highest level of precision to guarantee cost effectiveness and assure quality, which means that the limits of the mechanical system will inevitably be reached.
This prototype from the company, SCHNEEBERGER AG, was analysed using an FE model to ascertain its vibrational properties and improvements were made. The challenge lay in maintaining the eigenmode frequencies initiated by the table movements at a very high level.
The FE was generated directly from the 3D CAD drawings in data form enabling modelling work to be reduced to a minimum and the dynamic properties to be defined shortly after the construction phase of the major components.
