The Polaris Motion Control System

     

    EMPOWERING CNC MACHINE TOOL IDEAS

    Polaris Motion provides an empowering CNC motion control system to its customers. If you have a new machine idea or a new process that has advanced features and high performance, we can help. Our platform may already have what you're looking for.

    We provide technologies that make precision laser micromachining, precision laser additive manufacturing (LAM), precision 3D metal printing, and ultra precision optics manufacturing possible. We specialize in offering CNC motion controllers that have been designed for precision laser tools and ultra precision single-point diamond tools.

    Our CNC motion controllers are used for synchronizing stages, precision Galvo scanners and lasers. Our easy to use infinite field of view (IFOV) technology synchronizes XYZ stage motion and Galvo scanner motion automatically.

    Our CNC motion control system supports 3, 5 and full-featured 9 axis coordinated motion. High performance coordination and synchronization is provided for all XYZ-ABC-UVW axes.

    With our breadth of high end technologies and highly qualified team of engineers and scientists we are well equipped to bring your new ideas to market quickly.

     

    LEADER IN LASER BASED MANUFACTURING


    At Polaris Motion we provide off-the-shelf technologies for laser CNC manufacturing. A laser based CNC machine may be set up in days and weeks rather than months. The technology includes operator interface software, motion control software, drives and Galvo scanners. Standard part files such as DXF or STL are the interface. New parts may be designed or G-code files may be imported from third party CAD software. The motion controller and drives convert these to motion instructions that move the machine's stage and Galvo scanner. The software also includes machine vision for part inspection. Applications are boundless, from 3D metal 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 Galvo scanner motion is an integrated capability with advanced features such as stitching and infinite field of view (IFOV). 

     

    LEADER IN DIAMOND TOOL MACHINING

    For nearly two decades, Polaris Motion has been a leader in CNC motion 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 (fast tool servo, FTS) axes are seamlessly coordinated with advanced trajectory generation and path planning technologies.

     

    EVENT BASED MOTION

    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.

     

    ROBOTICS

    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.

     

    FAST ACTUATORS

    Polaris Motion has optimized its drive technologies for the fastest actuators, including Galvo scanner motors for laser CNC 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.

     

    SPINDLE MOTORS

    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.

     

    HIGH SPEED, HIGH RESOLUTION DATA

    Polaris Motion provides very high data rates for superior actuator performance. All kinematic variables use 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.

     

    SOFTWARE TOOLS

     

    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 CNC manufacturing. It supports everything from metal 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.
