Measurement in Aerospace Automation combined with the speed, accuracy and


fi delity of blue/white structured light scanning technology is especially useful in measuring the organic shapes of turbine blades, blisks, and stators, according to Gout. Instead of


measuring various cross sections at discrete locations, a blue/ white-light scanner measures the entire airfoil and captures the small leading and trailing radii as well as the twists and turns of the airfoil's organic shapes, he said.

Gout also noted casting manufactur- ers are using an automated system at different points in the process, fi rst to ensure wax cores are accurate, verifi ca- tion of the resulting castings and then confi rming a Maximum Material Condi- tion (MMC) “nesting of the part” within the casting before proceeding to fi nal machining. “The last thing you want to do is start machining a part and then fi nd out you did not have enough mate- rial to begin with,” he said.

FEATURES:


• Two Axis Slide • High Torque Digital Drive • Menu Prompted Touch Screen • Digital Read Out or Servo Positioned • Heavy Duty Stock Stops


Cut to the Finish


Modern Machine Tool has been building cutoff lathe machines for almost a century. Our lathes have evolved over the years into a completely automatic operation—from feed- ing to cutting to finishing. Our compact cast iron slide unit offers rigidity with the speed and serviceability of linear technology. The precision ground, ball-screw driven slides with high torque digital drives provide easy set up and increased tool life. An optional two axis servo slide is available for simple turning, boring and drilling operations. These systems can handle material .25” to 8”. Call us today and find out how speed and precision have become one.

To automate the ATOS Triple Scan 3D scanner, Capture3D developed a multiaxis motion control system called MC-XL. The six-axis system uses a closed-loop servo and belt driven actua- tors to move an ATOS sensor through 1710 × 750 × 2150 mm of travel. “This is ideal for meeting FAA requirements, since each turbine blade needs to be inspected individually, thus a high-vol- ume, high-capacity inspection process is mandatory,” said Gout. Scan volumes range from 38 mm to 2 m. “Capture 3D also offers commercial off-the-shelf [COTS] robotic scanning and inspection cells, some of which can be installed and operational in two days,” said Gout. He also explained the automated system can be equipped with a ‘kiosk mode’ in which operators identify themselves by scanning their badge barcode, choose an inspection routine for a particular part, load the part, and
