Process monitoring on gear cutting machines

Process monitoring makes gear cutting machines even more productive When cutting gears, optimizing tool life offers a significant potential for productivity improvements. Early replacement wastes usable tool life; if the wear mark is too wide, reconditioning requires excessive sharpening. This reduces the number of possible regrinds. Only monitoring of the actual wear ensures replacement at the correct time. Productivity gains using ARTIS process monitoring systems: • no additional operating costs • wear-dependent tool change or need-driven replacement of inserts • maximum number of tool regrinds...

The best monitoring for each gear cutting process Hobbing of small modules up to 5 mm on Liebherr gear cutting machines up to 500 mm workpiece diameter (LC 60 – LC 500) The hobbing of a gear up to module 5 mm often takes only a few seconds. The entire process, including initial cut, full cut, and deceleration is visualized in a curve. Monitoring uses mainly data collected during full cutting because this provides the most significant information. Deviations (red) indicate changes in the process, for example due to tool wear. Diameter compensation – the special plus offered by ARTIS Gear cutting...

Exclusive monitoring functions for Liebherr gear cutting machines Profile milling machines for internal and external gearing The use of profile milling machines to cut gears for large module internal and external gearing can also be reliably monitored with ARTIS systems. Each tooth gap is considered as an individual process. This enables simple comparison between the learning cut and all other machining for the same gearing, which also means that batch size 1 is possible. Similar to hobbing, the objective during profile milling is to identify wear and prevent insert breakage. Once again breakage...
