TurningMajority of lathe workFeed is from right to leftRough cut: large DOC, slow feedFinish cut: 1 or more cuts, less than 0.015 DOC
Tapered Turning Using Compound RestCompound rest set at desired angleCompound slide used to feed the toolLimited to short tapersDifficult to set taper accuracy
Tapered TurningUsing Taper AttachmentAttachment to carriage which controls movement of cross-slideLimited to tapers less than 6in./ft.
Tapered TurningOffset of the tailstockLimited to small tapersSeldom usedCNC Machine
BoringInternal turningEnlarging an existing hole
BoringPurposes:Make the hole concentric with axis of rotationImprove surface finishEnlarge holeCreate special features, i.e. o-ring grooveFeeds and DOC less in boring operations than turning due to tool overhangEquations for N and MRR the same as turning.
Lathe OperationsFacing Flat surface produced perpendicular to axis of rotation
Parting Operation that removes a finished part from the raw stock
Lathe OperationsKnurling A cold, forming process that produces a raised diamond pattern on the surface.
