modana ack machining prakriya haye jisamen ack kaatane kaa upkaran, aamtaur parr ack gair-rotary tool bitt, workpeace key ghoomate samay cumm yaa jyada raikhik roop seey aage badhkar ack helix toolpath kaa varnan kartaa haye.
aamtaur parr "modd" shabd iss kaatane kii kriya dwara "baahari" satahon kii peedhi key liye aarakshit haye, jabaki yeh vahee aavashyak kaatane kii kriya jaba "aantarik" satahon (chhed, ack prakaar yaa dusare key) parr lagu kii jaati haye tou ise "ubaau" kahaa jaataa haye. iss prakaar vakyansh "modd aur ubaau" prakriyaon key badey parivaar koo vargeekrit kartaa haye jise lathing key roop mein jaanaa jaataa haye. workpeace parr chehare kii kataai, chaahe vaha ack modd yaa ubaau upkaran key saath hoe, koo "saamana karna" kahaa jaataa haye, aur ise ack upasamuchchay key roop mein kissy bhee shreni mein jodaa jaa sakata haye.
modane koo haath seey, kharad key paaramparik roop mein kiya jaa sakata haye, jisake liye aksar operator dwara nirantar paryavekshan kii aavashyakta hoti haye, yaa ack swachaalit kharad kaa upayog karke joe naheen hotaa haye. aaj iss tarah key swachaalan kaa sabse aam prakaar computer sankhyaatmak niyantran haye, jise cnc key roop mein jaanaa jaataa haye. (see. aine. see. kaa upayog aamtaur parr modane key alawa kaee anya prakaar key machining key saath bhee kiya jaataa haye.)
jaba kaary-tukade koo ghumaaya jaataa haye (lakadi, dhaatu, plastic yaa patthar jaisi apekshaakrit kathor samagri kaa ack tukada) aur ack kaatane key upkaran koo sateek vyaas aur gaharaai kaa utpaadan karane key liye 1,2 yaa 3 akshon key saath ghumaaya jaataa haye. vibhinn jyaamiti mein nalika ghatakon kaa utpaadan karane key liye cylinder key baahar yaa ander (jise ubaau bhee kahaa jaataa haye) modd diyaa jaa sakata haye. haalaanki abb kaafee durlabh haye, praarambhik kharad kaa upayog jatil jyaamitiya aakritiyon, yahaan taka kii platonic thhos padarthon kaa utpaadan karane key liye bhee kiya jaa sakata haye; haalaanki cnc key aagaman key baad seey iss uddeshya key liye gair-computerykrit toolpath niyantran kaa upayog karna asamanya hoe gayaa haye.
modane kii prakriyaaen aam taur parr ack kharad parr kii jaati hain, jinhen sabse purana machine upkaran maanaa jaataa haye, aur vibhinn prakaar key hoe sakate hain jaise kii "seedha modd", "taper turning", "profiling" yaa "baahari groving". una prakaar kii modane kii prakriyaaen vibhinn aakar kii samagri kaa utpaadan curr sakati hain jaise kii "seedha", "shankudhari", "ghumaavdaar", yaa "groved" workpeace.
samanya taur parr, modane mein saral "ekal-bindu kaatane" upkaran kaa upayog kiya jaataa haye. workpeace samagri key pratyek samooh mein upkaran konon kaa ack ishtatam sett hotaa haye joe varshon seey vikasit kiya gayaa haye.
modane key sanchaalan seey apashisht dhaatu key tukadon koo chips (uttari america), yaa swarf (britten) key roop mein jaanaa jaataa haye. kuchh kshetron mein unhein "turnings" key roop mein jaanaa jaa sakata haye.
upkaran kii gati kii akshen shaabdik roop seey ack seedhi rekha hoe sakati hain, yaa way vakron yaa konon key kuchh sett key saath hoe sakati hain, lekin way anivarya roop seey raikhik hain (gair ganitiya arth mein).
ack ghatak joe sanchaalan koo modane key adheen haye, usey "parivartit bhaag" yaa "machini ghatak" kahaa jaa sakata haye. modane kaa sanchaalan ack kharad machine parr kiya jaataa haye jise haath seey yaa see. aine. see. dwara sanchaalit kiya jaa sakata haye.
sanchaalan koo modana.
vishisht sanchaalan mein shamil hainh
modane kii samanya prakriya mein ack bhaag koo ghumana shamil haye jabaki ack ekal-bindu kaatane vaale upkaran koo ghoornan kii dhuri key samanantar sthanantarit kiya jaataa haye. modd bhaag kii baahari satah key saath-saath aantarik satah (prakriya koo ubaau key roop mein jaanaa jaataa haye) parr kiya jaa sakata haye. praarambhik samagri aam taur parr casting, forging, extrusion yaa drying jaisi anya prakriyaon dwara utpann ack workpeace hoti haye.
modane key kaam key sandarbh mein, kaatane key upkaran koo sahee konn parr ghoornan kaary tukade key ghoornan kii dhuri parr leey jaanaa shamil haye. yeh cross-slide key sanchaalan dwara kiya jaa sakata haye, yadi ack fitt kiya gayaa haye, tou anudairdhya feed (modd) seey alag haye. yeh aksar workpeace key utpaadan mein kiya jaane vaalaa pahala operation hotaa haye, aur aksar antim hotaa haye-isaliye vakyansh "samaapt hotaa haye.
iss prakriya koo, jise parting off yaa cutoff bhee kahaa jaataa haye, kaa upayog gahari khaanche banaane key liye kiya jaataa haye joe apane mool stock seey ack poorna yaa aanshik-poorna ghatak koo hataa dega.
groving ack alag honey kii tarah haye, sivaay isake kii khaanche koo stock seey ack poorna/aanshik-poorna ghatak koo kaatane key bajaay ack vishisht gaharaai taka kaataa jaataa haye. groving koo aantarik aur baahari satahon key saath-saath hisse key chehare parr (chehare parr groving yaa trapening) kiya jaa sakata haye.
gair-vishisht sanchaalan mein shamil hainh
kharad.
kharad ack machine upkaran haye jiska upayog mukhya roop seey dhaatu, lakadi yaa anya samagriyon key tukadon koo aakar dene key liye kiya jaataa haye, jisase workpeace koo kharad dwara rakhaa aur ghumaaya jaataa haye, jabaki ack upkaran bitt koo kaatane kii kaarravaai key kaaran kaam mein unnat kiya jaataa haye. aasaani seey pehchaan key liye kharad koo teen prakaron mein vibhajit kiya jaa sakata haih injan kharad, burj kharad aur "vishesh uddeshya kharad". kuchh chhote bench mounted aur ardh-portable hotey hain. badey kharad farsh parr lagey hotey hain aur yadi unhein sthanantarit kiya jaanaa chaahiye tou vishesh parivahan kii aavashyakta hoe sakati haye.
khet aur rakharkhaav kii dukaanen aam taur parr ack kharad kaa upayog karati hain jise kaee sanchaalan key liye anukoolit kiya jaa sakata haye aur joe ack kaary sthal seey dusare kaary sthal parr leey jaane key liye bahut badaa naheen haye. injan kharad iss uddeshya key liye aadarsh roop seey upayukt haye. ack prashikshit prachaalak kissy bhee anya machine upkaran kii tulanaa mein injan kharad key saath adhik machining kaary puuraa curr sakata haye. burj kharad aur vishesh uddeshya vaale kharad kaa upayog aamtaur parr badey paimaane parr utpaadan yaa vishesh bhaagon key liye utpaadan yaa naukari kii dukaanon mein kiya jaataa haye, jabaki buniyaadi injan kharad kaa upayog aamtaur parr kissy bhee prakaar key kharad key kaam key liye kiya jaataa haye.
upkaran.
ack "ekal-bindu kaatane" upkaran key vibhinn konon, aakaron aur aakaron kaa machining sanchaalan mein ack workpeace kii parinami satah seey seedha sambandh hotaa haye. vibhinn prakaar key konn jaise "reck konn", "side reck konn", "cutting-aij konn", "raahat konn", "naak trijya" maujood hain aur workpeace key sambandh mein alag hoe sakate hain. isake alawa, "ekal-bindu kaatane" upkaran key kaee aakar hain, jaise "vee-aakar" aur "varg."aamtaur parr, operation key dauran kaatane key upkaran koo majbooti seey pakadane key liye ack vishesh upkaran dhaarak kaa upayog kiya jaataa haye.
modd kii gatishilata.
bull.
ack modd sanchaalan mein saapeksh bull machine upkaranon key design mein mahatvapurna hain. machine upkaran aur usake ghatakon koo operation key dauran mahatvapurna vikshepan, compan yaa gupshup kiye binaa inn balon kaa saamana karane mein saksham honah chaahiye. ack modd prakriya key dauran teen pramukh bull hotey hainh
gati aur feed.
cutter samagri, workpeace samagri, setup kathorta, machine upkaran kathorta aur spindle shakti, sheetlak vikalp aur anya karakon key aadhar parr gati aur modd key liye feed kaa chayan kiya jaataa haye.
