Trying to figure out what’s going on in this crazy economy of ours seems a bit like reading tea leaves—one part pseudoscience and three parts wild conjecture. Of course some pundits are telling us that this bull market has legs, while others insist that we’re due for a major correction. Some pump us up with positive news, while others remind us about scary stuff like the budget deficit, the European financial crisis and unemployment.
The shipping department is the closest
to the customer, and its main objective
is to maximize shipped orders every
month. Our lean guru shows how to eliminate waste in the shipping department.
When, in 1980, OSU professor Donald R. Houser created the Gear and Power Transmission Research Laboratory - then known as the Gear Dynamics and Gear and Power Transmission Laboratory (GearLab) - he did so with the seed money provided
by just three companies. Thirty-three years out, the lab has continued to grow, impress and—most importantly - succeed; it now boasts a roster of some 50 sponsoring companies and government agencies.
This paper proposes a method for the manufacture of a replacement pinion for an existing, large-sized skew bevel gear using multi-axis control and multitasking machine tool.
Audits of the heat treating department
are a vital part of any good quality program - either as part of a self-assessment or ISO program for a captive shop or - of equal importance - as part of an evaluation of the capabilities of a commercial heat treat supplier. In either case, the audit process needs to be formal in nature and follow specific guidelines.
The research presented here is part of an ongoing (six years to date) project of the Cluster of Excellence (CoE). CoE is a faculty-wide group of researchers from RWTH Aachen University in Aachen (North Rhine-Westphalia). This presentation is a result of the group’s examination of "integrative production technology for high-wage countries," in which a shaft for a dual-clutch gearbox is developed.
"Design for manufacturability" (DFM) is a well-established practice, essential to realizing the successful transformation of concepts into mass-produced gears and motion control
devices. And yet, all too often issues that could have been avoided are
identified very late in the process that
impact production costs and schedules.
This suggests that key DFM principles
are often underutilized in practice and
are not applied consistently - or to the
degree necessary - to avoid these negative results.
Hobbing is one of the most fundamental
processes in gear manufacturing. Its
productivity and versatility make hobbing
the gear manufacturing method of choice for a majority of spur and helical
gears.
Question: We manufacture some gears that require an axial face as a datum, as well as locating on the bore for centering. Other gears use only the bore for both axial and radial locating. What type of workholding is appropriate for each type of part? Is
there workholding that will work for both types?
