The ASRC develops and delivers a fully automatic laser marking machine to HAESL


On February the 14, the ASRC Digital Technology and Automation team delivered a fully automatic laser marking machine to HAESL in Junk bay.

The laser marking machine uses a QR code to identify the turbine/ engine blade or component which is then fixed in the machine. It is translated to the firing point of the laser under a ‘cold mirror’ and adjusted in the ‘z’ direction to give the correct focus of the laser and the machine vision camera. The image is analysed by complex, in house, proprietary software and the optimal point for marking is recommended by the computer. The operator accepts or over-rules this and the laser fires to make a precision mark on the chosen facet of the component. All of this is accomplished via machine vision and touch screen operation. The marks are visible and machine readable and comply with the Rolls Royce recommended depth and profile for laser marked parts.

The machine was delivered by Dr Sid Ho and Dr Steve O’Brien and accepted by Mr Nick Yeung on behalf of HAESL.
