A multi-axis precision motion system with higher dynamics and throughput targets must have a more holistic design approach to achieve success. There are many obvious advantages to the user when the mechanics, control electronics, and software of a system are designed by the same team.
Many laser micromachining and micro processing engineers face challenges of delivering laser pulses to a workpiece with a high degree of accuracy and repeatability, and developing a strong human machine interface (HMI) software through CAD/CAM post processing, motion profile generation, user interface and host programming, motion programming, laser control, and real-time IO control. This article discusses how these issues can now be solved with PI’s motion/CNC controller technologies that are designed to reduce complexity, and allow for faster time-to-market while improving the process accuracy.

Nanotechnology uses the concept that constant velocity will get you to the destination faster than constantly stopped traffic. One technique puts this concept into practice via a fast nano-focus device based on a piezo-ceramic actuator embedded in a flexure guided lens positioning mechanism.
As advances in computer performance are implemented, extraordinary performance levels will come from the use of silicon photonics, or the integration of optical circuits on semiconductor wafers, instead of the use of electronics.
The performance of precision metrology equipment such as coordinate measuring machines (CMM) depends on highly accurate, repeatable, and controllable motion systems and position sensors. Air bearings have played a critical role in the development and construction of CMMs and other metrology tools. They are inherently frictionless, highly stable, and feature geometric precision straightness and flatness for linear bearings.
The need for advances robotics with high precision and alignment requirements continues to grow in the automotive industry. Many traditionally used articulated-arm robots are fast and can handle heavy loads, but they lack positioning accuracy. In the past, hexapod parallel kinematic robots were considered overkill for the automotive industry. Now, however, the situation is rapidly changing. This white paper describes the major benefits that hexapod 6-axis parallel machines have for conventional robots in automotive precision assembly lines.
