Positioning systems

Our extensive expertise in the positioning and motion systems industry makes us a valued partner for the development of high precision systems. Whether your applications concerns the field of science, precision optical lenses, the semiconductor industry or analytical and testing, we are well-placed to provide you with high-tech solutions.

Design approach

We follow a structured and transparent design methodology. Ultimately, partnering with PM is synonymous with close cooperation and customer satisfaction.

From conceptual idea to final product, PM uses a V-model for engineering design. Of course, user requirements are the starting point of any design process.

In order to arrive at the best possible design, we start by bringing the key technical

 

challenges for each required function clearly into focus, so that a suitable design realisation can be found for each requirement. In this design phase PM applies one of its core competencies, i.e. the development of computational tools to fully characterise a system. This step precedes the building of any initial physical prototype. Our own Multibody Dynamics analysis tool was specifically developed for this stage in the design process. In particular, the tool allows for the following characteristics to be analysed:

  • Operational system dynamics

  • Full system Frequency Response Functions

  • Constraint force quantification

  • (Feed forward / closed loop) controller dynamics

When proceeding from the conceptual stage to detailed design realisations, the information obtained from the Multibody Dynamics analysis tool can be used to tune vibration isolation systems and serve as a benchmark for e.g. bearing design.

The overall result of this approach is that fewer design iterations are required, meaning a significant reduction in cost of development.

XY-stage for e-Beam application

This video shows a XY-stage design for a lithography application in the semiconductor industry.
The stage includes a direct drive mechanism for the both X and Y-axes. For increased stiffness and flatness a design with two sets of linear bearings with a double prism was realised. The rails have a uniquely developed mirror smooth finishing for extremely smooth running performance and positioning.
