Programming and laser drilling of simple or complex patterns
- Published: January 29, 2018
Prima Power Laserdyne has introduced SmartPerf, an application for programming and laser drilling of simple to complex patterns of holes in linear and cylindrical paths in 2D and 3D parts.
SmartPerf ensures higher quality holes, both in terms of metallurgy and geometry, with the benefit of reduced cycle time for “on-the-fly” laser drilling. Higher productivity is accomplished by eliminating the need for acceleration and deceleration at each hole location when comparing “on-the-fly” laser drilling to standard percussion laser drilling.
On-the-fly drilling with SmartPerf is a proven process for percussion drilling small diameter (0.2 to 0.6 mm) holes in turbine engine combustors. All of the Prima Power Laserdyne Nd:YAG and fiber laser systems can drill these holes at steep angles and in difficult-to-machine materials. Thousands of holes can be produced quickly over a 3D surface in a single setup.
SmartPerf is also used for producing patterns of holes involving both trepanning (cutting) and standard percussion drilling (move to a location and create the hole by delivering a sequence of pulses) in addition to on-the-fly drilling.
With SmartPerf, complex patterns involving non-uniform hole spacing and varying hole size are easily produced. Common applications involve drilling a pattern around a pre-existing machined feature (PHOTO ABOVE) and creating custom spray patterns based on an array of non-uniformly spaced, sized, and shaped holes.
Quality is enhanced because SmartPerf reduces heat input to the workpiece. This is especially important when laser drilling thermal barrier and other coated high temperature alloy metals. When used in conjunction with Laserdyne SmartPierce, results are even more effective since the process produces less debris, less heat and less part distortion.
