Lab Session #3 To carry out turning and taper turning (using compound rest method) on the lathe machine. Problem Statement The processes of lathe are Facing, turning and taper turning. As this process is about to reduce the diameter of work piece, so to perform the turning and taper turning process very properly we need to ensure the turning of work piece, the angle of tool and many other features required for a perfect turning of work piece. Objective To perform turning operation of a cylindrical work piece Properly give angels to the tool for proper taper turning operation. To reduce the diameter of work piece up to the measured & required readings. Apparatus Lathe machine L&N Key mild steel cylindrical work piece HSS single point cutting tool Theory Turning Turning is usually defined for cylindrical work pieces. This is used to reduce the diameter of a work piece. Turning is a form of machining, a material removal process , which is used to create rotational parts by cutting away unwanted material. The turning process requires lathe, work piece, fixture, and cutting tool. Taper Turning The taper turning is an operation of producing a conical surface by gradual reduction in the diameter of a cylindrical work piece.
Methods for Taper turning Taper tuning is performed, when a specific taper is required on work-piece. This can be
