Tooling U Work holding Questions with Answers All Correct

Tooling U Work holding Questions with Answers All Correct Angle Plate - Answer-A work holding device that consists of two surfaces connected at a 90° angle. Angle plates can securely hold rectangular workpieces or raise a workpiece from the worktable surface. Bar Feeding Machine - Answer-A device that continuously extrudes a long piece of bar stock at a steady rate. Bar feeding machines can be used with lathes and collets to quickly create a series of individual parts. Bar Stock - Answer-Raw material purchased from metal manufacturers in the form of long bars. Bar stock may be round, square, or hexagonal. Base Plate - Answer-A flat, rectangular fixture body with holes, slots, or both to allow the placement of fixture components. Base plates are set on a machine worktable for milling, drilling, or grinding operations. Bushings - Answer-A hardened metal tube, either fixed or removable, that is used to constrain or guide tools or to reduce friction. Bushings are used in jigs to guide cutting tools such as drills and reamers. Cams - Answer-A rotating circular surface used to transmit motion. Cams can be used to lock clamps into place. Changeovers - Answer-The process of switching a machine tool or workholding device from one setup to another for a different operation. Changeover speed can be improved through the use of power clamping for workholding. Collar - Answer-A circular component that surrounds and supports another component. Collars include the openings on collet faces, which surround and grip a workpiece during manufacturing operations. Cutting Fluid - Answer-A fluid used to cool, lubricate, and clear chips during a material removal process. Cutting fluid, or coolant, can improve tool life and finished part quality when used correctly. Destructive Testing - Answer-A part assessment method that places materials in harsh conditions that lead to part failure. Destructive testing, such as the guided bend test and transverse tension test, uses the application of force, meaning parts undergoing the tests must be held securely through workholding. Diameters - Answer-The distance from one edge of a circle to the opposite edge going through the center. Diameter describes the size of round and cylindrical workpieces and tools. Drill Plates - Answer-A jig component with a flat surface and carefully positioned holes. Drill plates guide the cutting tool in placing holes of the correct size and shape. Drill Presses - Answer-A machining tool with a multipoint cutting tool that penetrates the surface of a workpiece and makes a round hole. Drill presses can be used for a variety of holemaking operations. Honing - Answer-A finishing process that uses abrasive stones to grind away small amounts of workpiece material. Honing is used to create high quality surface finishes and tight tolerances. Hydraulic Clamping - Answer-A clamping system that uses the power created from compressed liquid to create the gripping force for clamps to hold a workpiece in place. Hydraulic clamping is generally used with larger workpieces over pneumatic clamps because the equipment takes up less space. Independent Chucks - Answer-A round lathe workholding device with jaws that open and close individually. Independent chucks require more operator intervention but center workpieces more precisely than self-centering chucks. Indexing - Answer-Moving a workpiece or machine component to another location in a fixed, controlled increment. Indexing allows for the precise machining of similar features in regular places on a part.
