-
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.
