20—GEAR Production Supplement P R O D U C T N E W S Edited by Stephanie Monsanty | Non-Contact Probe Enables Force-Free Measurement of Gear Profles Hexagon Metrology's HP-O non-contact scanning probe is intended to be an alternative to tactile analog measurement and scanning probes and is well-suited for scanning large parts and those that are rotationally symmetric. The device exerts no physical impact on the workpiece for force-free measurement of blisks, blades, gear profles, fank lines and other potentially deformable parts without a loss of accuracy. Its 3-mm diameter and measurement range of 20 mm provides access to points that are not accessible to tactile probes, the company says, and optical measurements can be captured in single-point or scanning mode. According to Hexagon, the probe delivers repeatability of less than 0.3 microns when used with its Leitz PMM-C CMM. Offering an acceptance angle of ±30 degrees, the probe can measure diffcult-to-access features at a scanning speed of 1,000 points per second for rapid throughput. Additionally, the probe's scanning technology is based on frequency-modulated interferometric optical distance measurement and is not affected by ambient light. It is multi-sensor compatible in a single part program using a standard toolchanger. Hexagon Metrology Inc. | 855-443-9638 | Software Eases Milling of Gears, Splines Sandvik Coromant's InvoMilling 1.0 software enables fexible manufacturing of gears and splines on universal fve-axis machining centers. Developed by Sandvik Coromant and Euklid, the CAM software generates CNC programs to produce different gear profles with a limited range of standard-stock precision tools. The software includes milling path generation and simulation functionality. According to Sandvik Coromant, when combined with its CoroMill 161 and 162 cutters, the InvoMilling software enables shorter lead times for production of gears and splines. The method is suitable for machining small- and medium-size batches. Sandvik Coromant Co. | 800-726-3845 |
