Workholding includes any device used to grip and present a workpiece to a cutting tool on a machine tool.
To provide an understanding of workholding as a fundamental issue in the machining processthis program, part of the Fundamental Manufacturing Processes Videoandnbsp;Series,andnbsp;examines the principles of workholding, millingandnbsp;and machining center workholding, and lathe workholding.
The principles of workholding segment covers datums, part location, the six degrees of freedom, the 3-2-1 locational method, and issues of reclamping or rechucking workpieces.
The millingandnbsp;and machining center workholding segment looks at small-lot, medium-lot, and mass-production workholding options while detailing the use of clamps, vises, multi-vises, cubes, columns, tombstones, indexers, rotary tables, modular fixturing, pallets, pneumatic clamping, hydraulic clamping, vacuum workholding, and application-dedicated fixtures.
The lathe workholding segment explores the use of three-jaw chucks, six-jaw chucks, four-jaw chucks, two-jaw chucks, indexing chucks, collets, collet chucks, between centers turning, drive dogs, face drivers, steady rests, and magnetic chucks and fixtures.
