BlueMotion is a Korean manufacture of precision linear motor driven stage and provide laser application for customers. When we challenge for advanced solution to promote new market, Polaris Motion was great partner. Specially, Polaris Motion is very powerful solution to implement high-end laser and robotics applications. We can always try new application with Polaris motion on faith together doubtlessly!
Lee, Gil-Young (President) of BlueMotion
Polaris Motion’s Infinite Field of View (IFOV) algorithm seamlessly coordinates the motion of a laser galvo scanner and a motorized stage. It is easy to set up, with only a single parameter to select. A slider allows the user to choose how much of the work is performed by the scanner versus the stage.
Polaris’ IFOV can be applied to many motion axes. The simplest implementation uses an XY stage and a 2D galvo scanner.
Unique to our company, Polaris IFOV can also coordinate a 5-axis XYZ-AC stage with a 3D galvo scanner. The motion of a 5-axis CNC machine or robot can be coordinated with a 3D galvo scanner seamlessly and with minimal effort.
2-Axis Applications
In 2D applications, key IFOV benefits include a larger effective working field, the ability to process larger parts, improved part quality with zero stitching error, a single coordinate system, and improved throughput.
3-Axis Applications
In 3D applications, IFOV on the Z axis eliminates the need to make compromised decisions with respect to the optical beam path. The laser spot size can be kept constant over large working volumes. When combining XY and Z IFOV, laser beam delivery does not need to be compromised in any way.
A unique feature of Polaris Motion’s IFOV technique is full compatibility with 5-axis CNC machine tool applications and 6-axis articulated robot arm applications.
Eliminate Stage Tracking Error
A highly responsive galvo scanner can be used to virtually eliminate servo tracking error caused by a high-inertia stage. Using the high-speed Mercury™ network, the X and Y stage servo errors are communicated to the galvo scanner axes and subtracted from the galvo axes’ setpoints, thereby implementing dynamic stage servo error compensation.
3D Galvoscanners
A 3D galvo scanner can be integrated with a 5-axis CNC machine tool to manufacture complex, rotational 3D laser-processed parts. Polaris Motion’s 5-axis IFOV accounts for the additional revolute axes. The coordination of mechanical and laser-optical axes into the XYZ Cartesian directions is transparent to the user, and ease of use is fully preserved.
This approach is general and can be applied similarly to 6-axis articulated robot arms. A 3D scan head can be attached to a robot end effector for use in remote welding applications, with the workpiece fixtured below.
Alternatively, a workpiece can be held by the robot gripper, while a 3D galvo scanner is mounted overhead for surface structuring.
