Keywords: Machine Tools power driven machine producing components required shape size desired accuracy surface finish removing material workpeices Machine Tools classified two criteria desired purpose; as Single purpose Multi-purpose special purpose Machine Tool size chip removed; as Machine Tools smaller sized chips like grinding machine pol hing machine Machine Tools larger size chips like Lathe Machine Drilling Machine Pol hing Machine When we speak about Machine Tools one most important types machine tools are: Lathe Machine: Machine tool which holds workpeice securely between two rigid strong supports while workpeice revolves cutting tool rigidly held supported while being fed against revolving workpeice lathe machine generally includes following parts: Bed Head-stock Tail-stock Carriage Feed Mechanism Thread cutting mechan m It can perform wide range operations that include straight turning step turning Eccentric turning taper turning facing drilling reaming boaring knurling thread cutting (ii) Drilling Machine: It produces holes in solid material using drill fitted in drill chuck rotating drill made harder material than that workpeice it fed using hand power feed High amount heat generated during process makes use coolant necessity basic elements drilling machine constitute base column work table drill head Spindle drive typical drilling machine can perform wide variety operations that include drilling reaming boring counter-boring counter-sinking spot-facing tapping Milling Machine: Milling process in which metal removal takes place due cutting action revolving cutter machine tool on which milling operation performed called as Milling Machine Milling Machine contains following elements base column knee table saddle over-arm table arbor Milling Machine can carry out lot operations including plane milling Angular Milling form milling slot groove milling saw milling slitting key-way milling Grinding Machine: Grinding process removing material abrasive action revolving wheel on surface workpeice removal takes place in form small chips Generally grinding wheel mounted on spindle driven an electric motor Due small size chips grinding considered as fin hing operation Grinding machines classified into two types Rough non-prec ion grinders Fine prec ion grinders Broaching Machines: Broaching machining operation in which tool called as broach make small cut through surface metal Broach either pushed pulled help broaching machine broach capable removing material as deep as 6 mm in one stroke produce variety shapes Broaching Machines classified on myriad categories like power employed direction movement broach cutting style type drive number pull heads Honing Machine: Honing an abrasive machining process that produces prec ion surface on metal workpeice scrubbing an abradive stone against it along controlled path Lapping Machine: Lapping an abrading process improving surface finish reducing roughness on surface lapping machine consists stationery upper plate rotary lower plate workpeice loaded in Conditioning rings on lower plate Lapping mainly smoothing engine valves surface plates crankshafts No machine tools complete without use gears Gears manufactured both metals non-metals like cast iron brass aluminium Generally all gears cut through gear generating processes which are Gear Shaper Process: pinion shaped cutter during process which carries tooth profile be cut gear blank introduced help sliding head cut using fro motion It suitable medium large size batches Gear Hobbing Process: cutter in th process called hob which worm like structure that carries gear profile parallel ax hob rotated at suitable speed fed into gear blank comes end quick revision machine tools time th episode's question: Multi tasking Machines (MTMs)? time answer our last ep ode's question: lubricants forging lubricant as thermal barrier restrict heat transfer workpeice die It acts as parting compound part sticking workpiece Mechanical Engineering Insider's Joining Processes
