Slide 1 - Lathe and drilling machines Unit V
Slide 2 - Manufacturing process It is a process which involves the conversion of raw materials into desired product.
Slide 3 - Methods involved Material removal Assembly or joining process Finishing process
Slide 4 - Material removal operation It involves removal of extra material from the given material to obtain required dimension of product. Material removal can be in small scale or large scale small scale – fitting, craftwork etc large scale – industrial products.
Slide 5 - Tool A tool is a device use to carry out various manufacturing operation. Hand tools. Machine tools
Slide 6 - Hand tools Tools which are used manually by human effort. Files hacksaw
Slide 7 - Machine tools Defined as power driven machine which accomplishes the cutting operation or machining operations.
Slide 8 - Lathe A lathe is machine tool employed generally to produce circular objects. Operations Drilling Grinding Shaping Milling
Slide 9 - Classification of lathe Engine lathe Speed lathe Turret lathe Capstan lathe Automatic lathe Computer numerically controlled lathe.
Slide 10 - Lathe principle of working A lathe works on the principle that “a cutting tool can remove chips from the rotating work pieces to produce circular objects”.
Slide 11 - Figure shows a work holding device known as chuck and is rotated a very high speed. A V-shaped cutting tool is held against the work piece. When the tool is moved parallel to axis of work piece material is removed.
Slide 12 - Lathe
Slide 13 - Major components Bed Head stock Tail stock Carriage assembly Main drive
Slide 14 - Bed It is the foundation part of lathe and supports all its parts. Top of bed has a guide way which is machined to precision. Head stock Main spindle projects out from headstock. Housing comprises of feed gear box and cone pulley. Rigidly mounted on bed.
Slide 15 - Tail stock Movable part of the lathe that carries dead centre. Main function is to support the free end of the work piece. Also used to clamp tools like twist drill and reamers for making holes. Tailstock is mounted loosely on guide ways can be moved and locked in position.
Slide 16 - ppt slide no 16 content not found
Slide 17 - Carriage assembly Saddle Cross slide Compound rest Apron Tool post
Slide 18 - ppt slide no 18 content not found
Slide 19 - Saddle H shaped casting that slides over the outer set of guide ways Serves as base for cross slide. Cross slide It is mounted on the saddle. Enables lateral movement of cutting tool laterally by means of cross slide handwheel.
Slide 20 - ppt slide no 20 content not found
Slide 21 - Compound rest Mounted on top of cross slide and supports the tool post. It can be swiveled at an angle to perform taper turning operation. Tool post It is used to clamp the tool holder in position.
Slide 22 - ppt slide no 22 content not found
Slide 23 - Apron It is the part which is fitted saddle, facing operator. It houses levers, hand wheels mechanism for manual and automatic movement of carriage assembly.
Slide 24 - Main drive It is an electric motor which drives the spindle through transmission system.
Slide 25 - Other component Lead screw It is a rod which runs longitudinally in front of lathe bed. The rotation of lead screw moves the carriage to and fro longitudinally during thread cutting operation.
Slide 26 - Lathe specifications Maximum diameter of the workpiece that can be revolved over the lathe bed. Maximum diameter and width of the workpiece that can revolve over gap in bed.
Slide 27 - Maximum length of workpiece that can be mounted between centers. Overall length of the bed.
Slide 28 - ppt slide no 28 content not found
Slide 29 - Lathe operations Turning Taper turning Facing Thread cutting Knurling
Slide 30 - Turning It is an operation in which the workpiece is reduced to the cylindrical section of required diameter.
Slide 31 - Operation is carried out with a single point cutting tool. Work piece is supported between the two centers permit rotation of workpiece.
Slide 32 - Tool is fed perpendicular to the axis of workpiece to a known depth and then moved parallel to axis of work.
Slide 33 - Facing An operation performed on lathe to generate flat surface. Direction of feed is perpendicular to the axis of the lathe.
Slide 34 - Length of the work should not be extended more than 1.5 times the diameter of the work piece.
Slide 35 - ppt slide no 35 content not found
Slide 36 - Knurling Operation performed on lathe to generate serrated surface. Tool used is called as “knurling tool”.
Slide 37 - ppt slide no 37 content not found
Slide 38 - Tool consist of one upper roller and one lower roller which contains the impression. Tool is set in such a way that both rollers touch the work.
Slide 39 - Low speed of about 60 to 80 rpm and feed is 0.38 to 0.78mm/revolution.
Slide 40 - ppt slide no 40 content not found
Slide 41 - Taper Turning It is the operation of reducing the diameter of the workpiece gradually along its length. Different types of Taper turning Compound slide swivelling method Tailstock offset
Slide 42 - Taper Turning by Swiveling the Compound Rest
Slide 43 - Axis of the tool is moved inclined to produce the required taper. Compound rest which supports tool post is swiveled at required taper angle and locked.
Slide 44 - ppt slide no 44 content not found
Slide 45 - ppt slide no 45 content not found
Slide 46 - Taper Turning by Tailstock offset
Slide 47 - In this method the workpiece is inclined with respect to the lathe axis. Tool movement is in line with the lathe axis to produce taper. Tail stock is shifted by a small distance called offset.
Slide 48 - Thread cutting A thread is a helical shaped groove formed on cylindrical surface of workpiece. Thread cutting is an operation performed on lathe to produce threads by using a tool whose shape will be same as that of thread.
Slide 49 - ppt slide no 49 content not found
Slide 50 - Drilling Drilling is an operation to produce a cylindrical hole in workpiece. Tool used is called as “drill bit”. Tool is held on the tailstock and stationary. Work is held in chuck. Tool is fed against the revolving work by rotating hand wheel.
