Experiment No.1 Objective: To identify construction, working and operation of lathe machine. Apparatus: •Lathe Machine •Cutting tools Theory: Lathe Machine Lathe Machine is a basic machine which is used in every metal forming industries. It is combination of many parts which works together to perform a desire function. A lathe machine is used to machine cylindrical work piece which is 360 o symmetrical form the axis of rotation. It is used to perform turning, chamfering, boring, facing, threading, shaping, slot cutting etc. on a cylindrical work piece. There are many parts of lathe machine but each machine consists of some basic parts which are essential for its proper working. These parts are bed, tool post, head stock, tail stock, legs, gear chain, lead screw, carriage, cross slide, split nut, apron, chip pan, guide ways etc. these parts work together to obtain desire motion of tool and work piece so it can be machined.
