The camera never lies!

GF Machining Solutions, the EDM, milling and laser ablation machine tool specialist and automation and tooling systems supplier, has introduced its latest (second generation) Integrated Vision Unit (IVU Advance) – an optical-based measurement system that improves productivity, accuracy and efficiency for wire EDM micro-machining applications.

IVU systemThe IVU Advance measurement (camera) system on GF Machining Solutions’ wire EDM machines.

When integrated with a wire EDM machine, the IVU system helps overcome the limitations and cost issues of on-machine part location.

The system locates part edges and scans part contours with a charge-coupled device (CCD) camera featuring a light-sensitive pixel array. By comparing an image of the part (after machining) whilst it’s still in the machine with the original CAD file, the IVU can identify any small deviations and correct the tool path automatically to ensure that all subsequent parts are precisely reproduced.

This provides manufacturers with significant productivity improvements and negates the need to remove parts from the machine to measure them on a separate CMM.

Comments Martin Spencer, Managing Director at GF Machining Solutions UK:

“The IVU Advance is a machine-integrated measurement system that improves process reliability and part accuracy.”

The CCD camera is available with either a 56x or a 156x magnification and employs two light sources – an incidental source at the camera lens, and a backlight source to enhance contrast.

The system converts the light intensity value for each pixel into an electronic signal with a corresponding value for each pixel.

With its larger field of view, the 56x magnification camera is appropriate for measuring larger parts, while the 156x magnification provides the detail and accuracy essential for measuring micron-scale parts. Typical users of the system, such as manufacturers in the micro-stamping industry and medical devices sector will be more likely to select the higher-magnification camera to maximize precision.
