Lab Session #3To carry out turning and taper turning (using compound rest method) on the lathe machine.Problem StatementThe processes of lathe are Facing, turning and taper turning. As this process is about toreduce the diameter of work piece, so to perform the turning and taper turning process veryproperly we need to ensure the turning of work piece, the angle of tool and many otherfeatures required for a perfect turning of work piece.ObjectiveTo perform turning operation of a cylindrical work pieceProperly give angels to the tool for proper taper turning operation.To reduce the diameter of work piece up to the measured & required readings.ApparatusLathe machine L&N Key mild steel cylindrical work pieceHSS single point cutting tool TheoryTurningTurningis usually defined for cylindrical work pieces. This is used to reduce the diameter of a work piece.Turningis a form of machining, a material removalprocess, which is used to create rotationalparts by cutting away unwanted material. Theturning processrequires lathe, work piece, fixture, and cutting tool.Taper TurningThetaper turningis an operation of producing a conical surface by gradual reduction in the diameter of a cylindrical work piece.
Methods for Taper turningTaper tuning is performed, when a specific taper is required on work-piece. This can be
