The Polaris Motion Control System



    Polaris Motion aims to deliver one of the most empowering CNC motion control systems in the world. If you have a new machine idea or new process with advanced features and high performance, then we are able to help. Our platform may already have all or most of what you are looking for.



    At Polaris Motion we provide off-the-shelf technologies for laser based manufacturing. A laser based CNC machine may be configured in days and weeks rather than months. The technology includes operator interface software, controls, drives and Galvoscanners. Standard part files such as DXF or STL are the interface, new parts may be designed or G-Code files imported from third party CAD. The controller and drives convert these to motion instructions that move the machine's stage and Galvoscanner motors. The software also includes machine vision for part inspection. Applications are boundless, from 3D printing to  laser cutting, drilling, ablating to laser patterning. All laser types are supported including continuous wave to pulsed, nanosecond to femtosecond, CO2, infrared to ultraviolet. Coordination of stage and Galvoscanner motion is an integrated capability with advanced features such as stitching and infinite field of view (IFOV). 



    For nearly two decades, Polaris Motion has been a leader in control technologies for diamond turning, grinding and diamond tool machining. Our 9 axes CNC technology is used to deliver the finest optics in the world for both civilian and military applications. Our customers' sub-nanometer form and finish capabilities are easily achieved with our path-planning and servo drive technologies. Low-bandwidth long-stroke and wide-bandwidth short-stroke (FTS) axes are seamlessly coordinated with advanced trajectory generation and path planning technologies.



    Polaris offers event based motion for up to 32 motion axes. Motions may run serially or in parallel. Customers may program their own event based processes to optimize machine throughput in parts per hour. Even at 32 servo axes each axis runs at 10kHz PID and set-point rates. Up to 9 of the axes may run a coordinated CNC process.



    Polaris Motion supports robotics natively with forward kinematics, inverse kinematics and the management of all Cartesian and joint robot variables. Customers are free to develop and implement their own kinematics and create software particular to their robot configuration.



    Polaris Motion has optimized its drive technologies for the fastest actuators, including Galvoscanner motors for laser based manufacturing  and fast tool servo (FTS) motors for super-high-bandwidth ultra-precise material removal. Feedback rates as high as 100kHz are supported with PID and additional digital high-pass, all-pass and notch filters.



    Polaris offers superior performance for spindle motor control. The highest quality air bearing spindle motors and rate tables are controlled with cycle to cycle repeatability as high as 1 part per million and superior intra-cycle stability.



    Polaris Motion provides very high data rates for superior actuator performance. All kinematic variables uses double floating point numerical representation. A machine having eight servomotor axes can run each axis at 50kHz set-point and PID rates. If four axes are used, each axis can run at 100kHz. If 32 axes are used each axis can run at 10kHz. Fast and slow axes may be mixed for best results. Data acquisition back to the host computer runs simultaneously for comprehensive and easy system diagnostics.




    Polaris Motion's software was designed to make it easier and faster for OEMs to integrate and deliver their machines to market. Software includes:

    •  CAD/CAM and Operator Interface Software
    •  Setup and Tuning Software
    •  Libraries and Development Tools

    Polaris CAD/CAM is a design, part file management and operator interface software. It's a comprehensive out-of-the box user interface for laser based manufacturing. It supports everything from 3D printing, cutting, drilling to laser patterning, and it includes machine vision.

    Polaris CNC Oi is an Operator interface for traditional CNC. It may be modified and extended by our customers for their particular needs.

    Polaris MotionTools is our machine setup and tuning software. It's an easy-to-use interface for setting up machine's encoders, phasing motors, digital I/O definitions and more. It has tools for PID tuning and signal analysis including real time digital oscilloscope, fast Fourier transforms (FFT), frequency response functions (FRF), tuning windows and more.

    Software libraries and development environments are available for Linux and Windows and include support for Microsoft Visual Studio, Borland and QT.
