PRIMA North America has introduced the new Laserdyne Model 450 five-axis laser system designed specifically for precision percussion and trepan drilling of turbine engine blades, nozzle guide vanes, shrouds, and similar size components.
The new laser system includes Laserdyne unique features such as the patented Optical Focus Control (OFC). OFC provides focus control for ceramic coated as well as metal surfaces along with probing of the surface prior to and during laser drilling.
This feature is coupled with BreakThrough Detection, a patent applied for feature, which improves hole consistency, reduces backwall strike damage, and increases throughput during processing.
Another feature is Active Optical Sensing (AOS). AOS is a combination of hardware and software, which monitors the state of optics during the drilling process. AOS warns the operator or will actually stop the process when the optics have been compromised.
The new Model 450 laser system is controlled by the Laserdyne S94P Laser Process Control designed specifically for integrated control of laser, motion and sensing functions for precision laser materials processing.
Representing the latest in PC-based control technology, the S94P software has been developed over two decades through experience in real-world turbine engine manufacturing. It includes a number of proprietary and patented features for laser cutting, drilling and welding.
The Model 450 laser system configuration consists of three (3) linear (X, Y, Z) and two (2) (A, B) rotary axes mounted on the X-Y axes. The workpiece and associated fixturing are mounted to the direct drive A (rotary) axis that in turn is positioned using a precision gear drive rotary table.
The 450 is equipped with a fully CNC controlled Convergent Lasers P50L pulsed Nd:YAG laser mounted outside the work area. The Model 450 has linear accuracy in the X, Y, Z axes of ±0.013mm/300mm (±0.0005 in/ft).
Accuracy in the rotary A, B axes is ±20 arc-second and ±6 arc-second respectively. The system has a part weight capacity of 18.2 kg for workpiece and fixturing. Overall machine footprint is 3.2m2.
