Metrology Gets Connected

“Metrology and its relationship to manufacturing is rapidly evolving,” Ken Woodbine, president, Wilcox Associates, a brand of Hexagon Metrology (North Kingstown, RI), recently observed. “We are seeing larger quantities and faster speeds of measurement data collection. The next challenge is what to do with all that data.”

Grinding Roots

Until the middle of 2010, first-tier subcontract machinist, JJ Churchill, could produce turbine blades only if they had their fir-tree root-forms preground elsewhere, or if they were subsequently added by another subcontractor. No longer is this the case.

Tooling and Workholding

Overall, there are two overriding customer needs: reducing cycle time and machine downtime. They want higher feed rates and depth of cut for greater metal removal.

Today’s Solid-Carbide Tools Are Top Producers

Solid-carbide round tools have seemingly been around forever; before them, high-speed steel (HSS) tools ruled the roost, and after them a growing selection of alternative processes like indexables, EDM, waterjet and now additive manufacturing emerged as competition.

New Tech Powers Grinding Ops

Abrasive machining is a tried-and-true technology for meeting exacting tolerances and producing superior finishes. Manufacturers continue to develop new capabilities.
