As a community, we gear engineers collaborate and share ideas to progress our collective capability. Technology progresses based on our efforts, and we have seen solid advances in the performance of our products as they become quieter, cheaper, more efficient, and more power dense. The pages of this magazine (past and present editions) are filled with examples where talented engineers have dug deeper into a subject using a more precise approach to a particular area concerning gear performance. The implied belief is always that greater precision (complexity) in the calculations brings greater accuracy (alignment with reality).
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.
Verisurf Software, Inc. introduces a new sales platform where customers can source new and pre-owned CMMs powered by Verisurf software. All machines are calibrated and certified and include Verisurf CMM Programming and Inspection Suite software.
With the release of the new Zeiss Inspect 3D metrology software, Zeiss offers its Industrial Quality Solutions customers numerous new functions. Zeiss Inspect Optical 3D is the solution for the inspection and evaluation of 3D measurement data. With this release, data acquisition is further accelerated and evaluation functions are further improved. The new Autosurfacing app also automatically converts scan data into a high-precision CAD model.
Differential gear manufacturers began moving away from the tried-and-true Revacycle broaching process to forgings some 30 years ago. At the time, forged differential gears seemed almost tailor-made to meet the needs of automotive, truck, and other vehicle producers: Relatively inexpensive when produced in high volumes; able to deliver the high power densities necessitated by the severe size constraints imposed by a differential cage; durable and robust.
To ensure all customers and their machines benefit from digital assistance, GF Machining Solutions (GFMS) has launched their new My rConnect platform engineered for the company’s EDM, milling, and laser texturing machines. The all-encompassing platform allows shops to connect any model of GFMS machine for fast, responsive, and easily accessible service and support while also providing expanded digital capabilities.
Sandvik has signed an agreement to acquire esco GmbH engineering solutions consulting, a German-based supplier of software for power skiving, an important technology within gear machining. Esco’s software solutions supports design, production and quality inspection in the main area of gear manufacturing. The company will be reported in Sandvik Coromant, a division within Sandvik Manufacturing and Machining Solutions.
