Precise positioning on the live image with the CPM Vision system

The CPM Vision System is used for camera-assisted positioning of laser markings. It displays the marking area as a live or single image and enables precise placement of the layout directly on the camera image or component. This allows markings to be visually checked and precisely aligned before the laser process starts.

The main differences lie in camera integration, image size, and resolution. The internal CPM is integrated into the beam path and offers maximum precision for small image sizes. The external CPM captures larger marking areas directly via the optics and is particularly suitable for larger components and flexible applications.

An internal CPM is particularly suitable when small components need to be positioned with very high accuracy. The integration of the camera in the beam path compensates for the thermal drift of the scanner, enabling particularly precise marking positioning. This requires the use of a fiber laser from the Business Fiber or Economy Fiber series.

The internal CPM is only available for fiber lasers, specifically for the DFL Ventus Marker from the Business Fiber and Economy Fiber series. The external CPM is available for diode lasers and CO₂ lasers.

The achievable image sizes and resolutions depend on the CPM variant.

With the internal CPM, the image sizes range from 5 × 5 up to 13 × 13 mm² (single image) or 35 × 35 up to 70 × 70 mm² (composite image) with a resolution of 6 up to 15 µm/pixel.

The external CPM achieves image sizes of 60 × 60 up to 160 × 160 mm² with resolutions of 65 up to 200 µm/pixel, depending on the optics and image size.

Without camera support, the positioning of the marking layout often has to be done manually and by eye. The use of a CPM Vision System reduces this source of error by supporting the user with a perspective-corrected live image. This significantly reduces the risk of incorrect markings, while increasing precision and process reliability.

No, the CPM Vision system does not require any additional software. It is fully integrated into the ACI Magic Mark marking software, so operation and positioning can be carried out directly in the familiar interface. However, it should be noted that CPM is a separate hardware module (camera unit) that must be present on the laser head or retrofitted. Camera-assisted positioning is only possible through the combination of hardware and Magic Mark.

Yes, the CPM Vision system can be retrofitted in many existing ACI laser stations. This makes it possible to equip existing systems with camera-based positioning and thus benefit from higher precision and process reliability—without having to purchase a completely new laser station.

The live image shows the entire marking area and allows the layout to be placed directly on the actual component. If required, a single image can also be used, which is automatically corrected and adapted to the marking area. This ensures that the virtual marking and the actual surface match exactly.

Stitching involves combining several individual images to form a single high-resolution image. This is particularly useful for small structures or delicate markings that would not be fully visible in the live image. Stitching provides the user with a detailed representation for maximum precision.
