LG Motion: Laser machining made easy

 

LG Motion have recently launched a new piece of software to make laser machining and 3D printing easier.

The release of new CAD/CAM software from Polaris enables a machine operator to be able to design parts, import part files run by the machine and inspect the finished product. The single piece of advanced software also controls the laser source, positioning stage, galvoscanner and machine vision camera.

Working closely with a number of specialist motion control specialists we are able to offer complementary products that enable our engineering team – and our clients – with a comprehensive range of motion control solutions.

Polaris Motion specialises in the design and development of control solutions for CNC machines in laser-based manufacturing, diamond tool cutting and grinding of optical surfaces and for other specialised CNCS used in high-performance applications.

Comprehensive and Flexible

The new software allows a wide range of 2D and 3D CAD files to be imported. Objects are easy to draw – lines, circles, arcs and rectangles – and you can draw by hand and add precision parameters for size and position. All parameters such as size, position, motion and laser parameters can also be entered as variables which are easy to control and change.

The video demonstrates engraving the image of a Parrot using Infinite Field of View (IFOV) technology. The size of the image is larger than the Galvoscanner field. The XYZ stage and Galvoscanner are automatically co-ordinated and synchronized with the laser triggering to maximum the speed and accuracy of engraving.

Additional Features and Functions

  • Polaris CAD/CAM has a stitching tool and infinite field of view (IFOV) to combine fast motion of the Galvoscanner and the long stroke motion of the stage. Stitching allows the division of a large object into tiles and centring each object in the Galvo field. Infinite field of view synchronises and coordinates stage motion and Galvoscanner motion automatically.
  • Hardware in the laser CNC machine can be controlled through digital and analogue I/O and
    serial port commands.
  • The software includes a virtual joystick to control the positioning stage manually.
  • Polaris CAD/CAM integrates machine vision with laser machining processes. Machine vision can be used to inspect actual markings or it can be used to superimpose fabrication trajectories onto the image of the cut part. The camera view is calibrated to match the stage coordinates. Several cameras may be used, for both wide and zoomed-in views.
