Among these are the SP94P control, which includes as


a standard feature a full complement of dedicated hardware and software features. These include Automatic Focus Control for capacitive part sensing, patented Optical Focus Control (OFC) for sensing of thermal barrier coated surfaces, Shape- Soft software for programming shaped holes, Break Through Detection for drilling clean, consistent holes with the minimum number of pulses, and multibuffer capable mapping. The Optical Focus Control (OFC)/Automatic Focus Control (AFC) feature is particularly important to Hi-Tek’s work. Continuously refi ned so that both hardware and software is leading edge, OFC/AFC precisely guides the motion system, maintaining critical focus position and following the contour of the part regardless of slight surface irregularities. With all machine axes reacting to sensing of the part surface, this creates unlimited R-axis correction with high speed and sensitivity. OFC/AFC allows top machine speeds so produc- tivity is maximized without downtime or scrapped parts. The SP94P control also allows Hi-Tek to use programs created for


Five-axis laser beam motion allows effi cient use of the work envelope, enabling processing at complex angles.


Turbine parts have complex cooling-hole requirements. Laserdyne systems drill holes in these high-temperature materials with high-speed accuracy.


its other Laserdyne systems with little or no modifi cation. As for speed, the new Laserdyne fi ber laser system operates at up to 800 ipm in all axes (0–20 m/min) with bidirectional accuracy of 0.0005" (12.7 µm). This accuracy is throughout the system’s 80 × 40 × 40" (2 × 1 × 1-m) work


envelope, making it ideal for demanding process validation and reliability requirements. Accuracy of the new system is certifi ed to ISO 230-1:1996 and 230-2:2006 in accordance with Prima Power Laserdyne’s standard accuracy and repeat- ability test procedures. “We feel strongly that the addition of the 795XL with all of its latest control features along with new fi ber laser allows us to improve our throughput and quality while providing a plat- form for both larger and more complex components requiring drilling, welding and cutting,” reported Stang. With only a few months of use, Stang’s overall appraisal of the new Laserdyne 795XL fi ber laser quality is quite high stating that “the trepan quality is excellent with very little exit burr. Maintenance of the new fi ber laser system hasn’t been an issue. Our operators like operating the system. All of our folks here have enjoyed a good relationship with Laserdyne ever since we bought our fi rst system in 1995.”
