Open Mind Technologies, a leading developer of hyperMILL CAD/CAM software solutions worldwide, announced it has joined the Georgia Tech Manufacturing 4.0 Consortium. The consortium is a membership-based organization that facilitates key collaborations between industry, academia, and government to develop and deploy advanced manufacturing technologies as well as provide workforce development. Initial members have contributed funding, technology, and skilled resources supported by the staff at the Georgia Tech AI Manufacturing Pilot Facility located in Atlanta, GA.
UK-based PTG Holroyd has announced that going forward, all models in its TG Series of ultra-precise helical rotor and thread grinding machines will be equipped with the Siemens digitally native Sinumerik One CNC as standard.
This paper presented some steps to get more insight into the effect of meshing damping on the dynamic response and noise emission of a two-stage gearbox transmission system. For this purpose, two variants of the model with different gear materials, one with plastic gears and one with steel gears, were considered. Both variants were designed for the same number of cycles of operation with similar root and flank safeties. The forced response analysis of the models was carried out and the exciting reaction bearing forces were calculated to evaluate which model can achieve better NVH characteristics results with lower noise emission from the housing.
