High Performance Motion Control – Systems Approach Provides Nanometer Precision for Industrial Applications

High performance motion control plays a key part in positioning and handling applications, such as those in semiconductor manufacturing, laser and materials processing, optical inspection systems, additive manufacturing or industrial digital printing. In addition to providing reliability and robustness, deterministic behavior with minimized latency, high-speed synchronization with external devices, such as lasers and cameras, is […]

Precision Robotics and Automation: Hexapods Advance Production Processes

Summary Hexapods, six-legged parallel-kinematic machines, are quickly gaining ground in a broad range of industrial automation applications after “learning” how to directly communicate with PLC or CNC controllers via fieldbus interfaces. As far as the semiconductor and electronics industry, automobile industry, and precision assembly are concerned, many production processes have become inconceivable without them. Today, […]

High Load Hexapod Test and Assembly

Testing and Qualifying Positioning Systems for Multi-Ton Loads The nano- and micro world is not limited to microscopic loads. Optics in astronomical telescopes and semiconductor lithography equipment are getting larger and heavier, while alignment tolerances that need to be met are getting tighter. Hexapod parallel-kinematic motion and positioning systems are often used in multi-axis alignment […]

Measuring the Smallest Resolution of a Positioning Stage

The trace above, measured by a laser interferometer, shows peak-to peak noise (black) of a linear motor positioning system on the order of 1.8 nm (controller is actively holding a position, no position change commanded). The noise measured by the external metrology (laser) contains the sum of all mechanical and electrical sources – the amplifier […]

Force & Position Control in Precision Automation

A host of applications can benefit from fast actuation systems equipped with precise metrology for controlling both force and position accurately. These include: Fast production testing of touch- and force-sensitive and haptic components; Delicate, high-speed automated assembly procedures where position vs. force is important; Testing of physical characteristics such as compliance, damping or other material […]
