Ukujika kusebenzisa i-lathe ukususa izinto ngaphandle kwendawo yokusebenza ejikelezayo, ngelixa i-boring isusa izinto ngaphakathi kwendawo yokusebenza ejikelezayo.#isiseko
Ukuguqula yinkqubo yokususa izinto kwi-diameter yangaphandle ye-workpiece ejikelezayo usebenzisa i-lathe.Abasiki benqaku elinye basika isinyithi ukusuka kwisixhobo sokusebenza sibe (ngokufanelekileyo) iitshiphusi ezimfutshane, ezibukhali ekulula ukuzisusa.
I-CNC lathe kunye nokulawulwa kwesantya sokusika rhoqo ivumela umqhubi ukuba akhethe isantya sokusika, kwaye emva koko umatshini ulungelelanisa ngokuzenzekelayo i-RPM njengoko isixhobo sokusika sidlula ububanzi obuhlukeneyo kunye ne-contour yangaphandle ye-workpiece.Iileyile zanamhlanje zikwafumaneka kwi-turret enye kunye noqwalaselo lwe-turret ephindwe kabini: ii-turrets enye ine-axis ethe tyaba kunye nethe nkqo, kwaye ii-turrets eziphindwe kabini zinezibini ezithe tye nezithe nkqo kwi-turret nganye.
Izixhobo zokujika zakwangoko yayiziziqwenga eziluqilima eziluxande ezenziwe ngesantya esiphezulu sentsimbi eneharika kunye neekona zokuvula kwelinye icala.Xa isixhobo sisiba buthuntu, umkhandi wesitshixo usilola kwisixhobo sokusila ukuze sisetyenziswe ngokuphindaphindiweyo.Izixhobo ze-HSS zisaxhaphakile kwiileyile ezindala, kodwa izixhobo ze-carbide ziye zaziwa ngakumbi, ngakumbi kwifom ye-brazed single point.I-Carbide inokumelana nokunxiba okungcono kunye nobunzima, okwandisa imveliso kunye nobomi besixhobo, kodwa kubiza kakhulu kwaye kufuna amava ukubuyisela kwakhona.
Ukujika kukudibanisa umgca (isixhobo) kunye ne-rotary (workpiece) intshukumo.Ngoko ke, isantya sokusika sichazwa njengomgama wokujikeleza (obhalwe njenge-sfm - i-surface foot ngomzuzu - okanye i-smm - i-square meter ngomzuzu - ukuhamba kwenqaku phezu kwenxalenye ngomzuzu omnye).I-feedrate (echazwe ngee-intshi okanye i-millimeters nge-revolution) ngumgama onqamlekileyo isixhobo esihamba kunye okanye ngaphesheya kwendawo yokusebenza.Ukutya kwakhona ngamanye amaxesha kuchazwa njengomgama omgca (in/min okanye mm/min) esiwuhambayo isixhobo ngomzuzu omnye.
Iimfuno zesantya sokutya ziyahluka ngokuxhomekeke kwinjongo yokusebenza.Umzekelo, kwi-roughing, ukutya okuphezulu kudla ngokuba ngcono ekwandiseni amaxabiso okususwa kwesinyithi, kodwa inxalenye ephezulu yokuqina kunye namandla omatshini ayafuneka.Kwangaxeshanye, ukugqiba ukujika kunokucothisa isantya sokutya ukuze kuphunyezwe uburhabaxa bomphezulu obuchazwe kumzobo wenxalenye.
Ukusebenza kwesixhobo sokusika kuxhomekeke kakhulu kwi-angle yesixhobo esinxulumene nomsebenzi.Amagama achazwe kweli candelo asebenza ekusikeni nasekufakeni ucoceko kwaye ayasebenza nakwizixhobo eziqhagamshelwe kwindawo enye.
I-engile yeraki ephezulu (ekwabizwa ngokuba yi-engile yerake yangasemva) yi-engile eyenziwe phakathi kwe-engile yokufaka kunye nomgca othe gqolo kwisixhobo sokusebenza xa ujongwe kwicala, ngaphambili nangasemva kwesixhobo.I-engile ephezulu yeraki ilungile xa i-engile yeraki ithotywa ukusuka kwindawo yokusikwa ukuya kwi-shank;ukungathathi hlangothi xa umgca ophezulu wokufaka uhambelana nomphezulu we-shank;kwaye ingathathi hlangothi xa ithotywe ukusuka kwindawo yokusika.iphezulu kunesibambi sesixhobo, i-engile yeharika ephezulu ayinambi..Iiblades kunye nezibambo nazo zohlulwe zibe zii-engile ezilungileyo nezingalunganga.Ufakelo olunotyekelo olufanelekileyo lunamacala akrazukileyo kunye nezibambi ezifanelekileyo ezineengile eziphozithivu kunye necala lehariki.Ufakelo olungalunganga lusisikweri ngokumalunga nomphezulu wencakuba kwaye zilungele izibambo ezinomphezulu ongalunganga kunye nee-engile zehariki ezisecaleni.I-engile ephezulu yeraki yohlukile kuba ixhomekeke kwijometri yofakelo: ii-chipbreakers eziphantsi komhlaba eziqinisekileyo okanye ezenziweyo zinokutshintsha i-engile ephezulu yehariki ukusuka kwi-negative ukuya kwi-positive.Ii-engile zeraki eziphezulu zikholisa ukuba nkulu kwizinto ezithambileyo, ezithambileyo ngakumbi ezifuna ii-engile zokucheba ezinkulu, ngelixa izinto eziqinileyo, eziqinileyo zisikwa ngcono ngokungathathi hlangothi okanye kwejiyometri engalunganga.
I-engile yeraki esecaleni eyenziwe phakathi kobuso bencakuba kunye nomgca othe tyaba kwi-workpiece, njengoko kubonwa ukusuka ekupheleni kobuso.Ezi zi-angles zilungile xa zihlanjululwe kude ne-edge edge, zingathathi hlangothi xa zi-perpendicular ukuya kwi-cutting edge, kunye ne-negative xa zihlanjululwe phezulu.Ubunzima obunokwenzeka besixhobo buxhomekeke kwi-angle ye-rake yecala, ii-engile ezincinci zivumela ukusetyenziswa kwezixhobo ezityebileyo ezonyusa amandla kodwa zifuna amandla aphezulu okusika.Ii-angles ezinkulu zivelisa ii-chips ezincinci kunye neemfuno ezisezantsi zokusika, kodwa ngaphaya kweyona ndawo iphakamileyo ekhuthazwayo, i-edge yokusika iyancipha kwaye ukuhanjiswa kobushushu kuyancipha.
I-bevel yokusika isiphelo yenziwe phakathi komda wokusika we-blade ekupheleni kwesixhobo kunye nomgca we-perpendicular ukuya ngasemva kwesibambo.Le angle ichaza i-gap phakathi kwesixhobo sokusika kunye nomgangatho ogqityiweyo we-workpiece.
Isiphelo sokugqibela sifumaneka ngaphantsi kwesiphelo sokusika kwaye senziwe phakathi kobuso bokugqibela bokufaka kunye nomgca we-perpendicular kwisiseko se-shank.I-Tip overhang ikuvumela ukuba wenze i-angle yokunceda (eyenziwe nge-shank end kunye nomgca we-perpendicular kwingcambu ye-shank) inkulu kune-angle yokunceda.
I-angle yokucoca ngecala ichaza i-angle phantsi kwecala lokusika.Yenziwe ngamacala e-blade kunye nomgca we-perpendicular kwisiseko somqheba.Njengomphathi wokugqibela, i-overhang ivumela ukukhululeka kwecala (okwenziwe ngecala lesiphatho kunye nomgca we-perpendicular ukuya kwisiseko somqheba) ukuba ube mkhulu kunokukhululwa.
I-angle ekhokelayo (eyaziwa nangokuthi i-angle yokusika i-angle edge okanye i-lead angle) yenziwe phakathi kwecala lokusika i-edge yokufakwa kunye necala lomnini.Le angle ikhokela isixhobo kwi-workpiece, kwaye njengoko isanda, i-chip ebanzi, encinci iyaveliswa.Ijometri kunye nemeko yezinto eziphathekayo zizinto eziphambili ekukhetheni i-angle ehamba phambili yesixhobo sokusika.Umzekelo, izixhobo ezine-angle ye-helix egxininisiweyo zinokubonelela ngokusebenza okubalulekileyo xa usikwa i-sintered, i-discontinuous, okanye i-hardware ngaphandle kokuchaphazela kakhulu umda wesixhobo sokusika.AbaSebenzi kufuneka balungelelanise le nzuzo kunye nokwanda kokuphambuka kunye nokungcangcazela, njengoko ii-engile zokunyusa ezinkulu zenza amandla amakhulu eradial.Izixhobo zokuguqula i-pitch zero zibonelela ngobubanzi be-chip obulingana nobunzulu bokusikwa kwimisebenzi yokuguqula, ngelixa izixhobo zokusika ezine-angle yokuzibandakanya zivumela ubunzulu obusebenzayo bokusikwa kunye nobubanzi be-chip obuhambelanayo ukuba bugqithise ubunzulu bokwenyani bokusikwa kwi-workpiece.Uninzi lwemisebenzi yokuguqula ingenziwa ngokufanelekileyo ngoluhlu lwe-angle yokusondela ye-10 ukuya kwi-30 degrees (inkqubo ye-metric ibuyisela i-engile ukusuka kwi-90 degrees ukuya kwelinye, isenza uluhlu olufanelekileyo lwe-engile ye-80 ukuya kuma-60 degrees).
Zombini incam kunye namacala kufuneka ube nokukhululeka okwaneleyo kunye nokukhululeka ukwenzela ukuba isixhobo singene ekusikeni.Ukuba akukho sithuba, akukho chips ziya kubumba, kodwa ukuba akukho sithuba esaneleyo, isixhobo siya kuxubha kwaye sivelise ubushushu.Izixhobo zokuguqula indawo enye nazo zifuna ukukhululeka kobuso kunye necala ukuze ungene kwi-cut.
Xa ujika, i-workpiece iphantsi kwe-tangential, i-radial kunye ne-axial cutting forces.Impembelelo enkulu ekusetyenzisweni kwamandla isetyenziswa ngamandla e-tangential;Amandla e-axial (ukutya) cinezela inxalenye kwicala le-longitudinal;kunye ne-radial (ubunzulu bokusika) amandla athande ukutyhala i-workpiece kunye nesibambi sesixhobo.“Amandla okusika” sisimbuku sale mikhosi mithathu.Kwi-engile engu-zero yokuphakama, zikumlinganiselo we-4:2:1 (tangential:axial:radial).Njengoko i-angle ehamba phambili inyuka, amandla e-axial ayancipha kwaye amandla okusika i-radial ayanda.
Uhlobo lweshanki, ireyidi yekona, kunye nokumila kofakelo nako kunempembelelo enkulu kobona bude buphezulu bomphetho osebenzayo wokusika wofakelo olujikayo.Iindibaniselwano ezithile zokufaka iradiyasi kunye nesibambi zinokufuna imbuyekezo yobukhulu ukuze kuxhamle ngokupheleleyo umphetho wokusika.
Umgangatho womphezulu kwimisebenzi yokuguqula ixhomekeke kukuqina kwesixhobo, umatshini kunye nomsebenzi.Nje ukuba ukuqina kumiselwe, ubudlelwane phakathi kokutya komatshini (kwi/rev okanye mm/rev) kunye nokufaka okanye iprofayili yempumlo yesixhobo ingasetyenziselwa ukumisela umgangatho womphezulu womsebenzi.Iprofayili yempumlo ibonakaliswa ngokwerediyasi: kwinqanaba elithile, iradiyasi enkulu ithetha ukugqitywa komphezulu ongcono, kodwa iradiyasi enkulu kakhulu inokubangela ukungcangcazela.Kwimisebenzi yomatshini efuna ngaphantsi kweradiyasi eyiyeyona ilungileyo, umyinge wesondlo unokufuna ukuncitshiswa ukufezekisa isiphumo esifunekayo.
Nje ukuba inqanaba lamandla elifunekayo lifikelelwe, imveliso iyanda ngobunzulu bokunqunyulwa, ukondla kunye nesantya.
Ubunzulu bokusika bulula kakhulu ukunyuka, kodwa ukuphuculwa kunokwenzeka kuphela ngezinto ezaneleyo kunye namandla.Ukuphinda kabini ubunzulu bokusikwa kwandisa imveliso ngaphandle kokunyusa ubushushu bokusika, amandla okuqina, okanye amandla okusika nge-intshi nganye ye-cubic okanye isentimitha (ekwaziwa njengamandla athile okusika).Oku kuphinda kabini amandla afunekayo, kodwa ubomi besixhobo abuncitshiswanga ukuba isixhobo sihlangabezana neemfuno zamandla okusika tangential.
Ukutshintsha umyinge wesondlo nako kulula noko.Ukuphinda kabini umyinge wesondlo kuphinda kabini ubukhulu be-chip kunye nokwanda (kodwa akuphindi) amandla okusika, ukusika ubushushu, kunye namandla afunekayo.Olu tshintsho lunciphisa ubomi besixhobo, kodwa hayi ngesiqingatha.Amandla athile okusika (amandla okusika anxulumene nobungakanani bezinto ezisusiweyo) nawo ayancipha ngokunyuka kwesantya sokutya.Njengoko izinga lokutya linyuka, amandla angaphezulu asebenza kumda wokusika anokubangela ukuba i-dimples yenze i-rake surface ye-insert ngenxa yokushisa okwandayo kunye nokuxhatshazwa okwenziwa ngexesha lokusika.Abaqhubi kufuneka babeke iliso ngononophelo olu tshintsho ukunqanda ukusilela okuyintlekele apho iitshiphusi ziba namandla kunencakuba.
Akunabulumko ukunyusa isantya sokusika xa kuthelekiswa nokutshintsha ubunzulu bokusika kunye nesantya sokutya.Ukunyuka kwesantya kwakhokelela ekunyukeni okukhulu kweqondo lokushisa kunye nokunciphisa i-shear kunye nemikhosi ethile yokusika.Ukuphinda-phinda isantya sokusika kufuna amandla awongezelelweyo kwaye kunciphisa ubomi besixhobo ngaphezu kwesiqingatha.Owona mthwalo kwiharika ephezulu ungacuthwa, kodwa amaqondo obushushu aphezulu okusika asabangela iicraters.
Ukufakela ukunxiba kuphawu oluqhelekileyo lwempumelelo okanye ukungaphumeleli kwawo nawuphi na umsebenzi wokuguqula.Ezinye izikhombisi eziqhelekileyo ziquka iitshiphusi ezingamkelekanga kunye neengxaki kunye nomsebenzi okanye umatshini.Njengomgaqo jikelele, umqhubi kufuneka abonise i-insert kwi-0.030 in. (0.77 mm) i-flank wear.Ukugqiba imisebenzi, umqhubi kufuneka abonise kwimigama ye-0.015 in. (0.38 mm) okanye ngaphantsi.
Abanini bokufaka izalathiso ezibotshwe ngoomatshini bathobela imigangatho elithoba yenkqubo ye-ISO kunye ne-ANSI.
Ileta yokuqala kwinkqubo ibonisa indlela yokufaka i-canvas.Iindidi ezine eziqhelekileyo zongamele, kodwa uhlobo ngalunye luneentlobo ezininzi.
Ufakelo lwe-C lusebenzisa i-clamp ephezulu kwiifakelo ezingenawo umngxuma ophakathi.Inkqubo ixhomekeke ngokupheleleyo kukhuhlane kwaye ifaneleke kakhulu ukuba isetyenziswe ngokufakela okulungileyo kwindawo ephakathi ukuya kokukhanya okujikayo kunye nezicelo ezikruqulayo.
Ufaka uM bamba iphedi ekhuselayo yomqolo wokufaka kunye nesitshixo secam esicinezela into efakiweyo eludongeni lomngxuma.I-clamp ephezulu ibamba umva we-insert kwaye ithintele ekuphakanyisweni xa umthwalo wokusika usetyenziswe kwincam yokufaka.Ufakelo lwe-M lufaneleke ngokukodwa ukufakwa okuphakathi komngxuma ophakathi ukuya kobunzima.
Izifakelo zodidi lwe-S zisebenzisa izikrufu zeTorx okanye ze-Allen ezingenanto kodwa zifuna ukutshona okanye ukutshona.Izikrufu ziyakwazi ukubamba kumaqondo obushushu aphezulu, ngoko ke le nkqubo ifaneleka kakhulu kukukhanya ukuya kumodareyitha ukujika kunye nemisebenzi ekruqulayo.
Ukufakwa kwe-P kuhambelana nomgangatho we-ISO wokujika iimela.I-insert icinezelwe eludongeni lwepokotho nge-lever ejikelezayo, ejikelezayo xa i-screw yokulungelelanisa isetyenzisiwe.Olu fakelo lufanelene kakhulu nokufakwa kweraki engalunganga kunye nemingxuma ephakathi ukuya kobunzima bokuguqula izicelo, kodwa aziphazamisi ukunyusa kokufaka ngexesha lokusika.
Inxalenye yesibini isebenzisa oonobumba ukubonisa imilo yencakuba.Inxalenye yesithathu isebenzisa oonobumba ukubonisa indibaniselwano yee-shanks ezithe tye okanye ze-offset kunye ne-helix angles.
Ileta yesine ibonisa i-angle yangaphambili yesiphatho okanye i-angle yangasemva ye-blade.Kwi-engile yeharika, i-P yi-engile ephozithivu yeharika xa isixa se-engile yokucoca isiphelo kunye ne-engile wedge ingaphantsi kwama-90 degrees;U-N yi-engile ethabathayo xa isibalo sezi engile sikhulu kuno-90 degrees;O yi-engile yeraki engathathi hlangothi, isixa sayo esiziidigri ezingama-90 ngqo.I-angle yokucoca ngokuthe ngqo iboniswa ngoonobumba abaninzi.
Owesihlanu ngunobumba obonisa isandla esinesixhobo.U-R ubonisa ukuba sisixhobo sasekunene esisika ukusuka ekunene ukuya ekhohlo, ngelixa u-L ehambelana nesixhobo esisekhohlo esisika ukusuka ekhohlo ukuya ekunene.Izixhobo ze-N zingathathi hlangothi kwaye ziyakwazi ukusika kuyo nayiphi na indlela.
Amacandelo 6 kunye ne-7 achaza umahluko phakathi kwe-imperial kunye ne-metric systems yokulinganisa.Kwinkqubo yobukhosi, la macandelo ahambelana neenombolo ezimbini ezibonisa icandelo lesibiyeli.Kwi-square shanks, inani lisixa sesinye kwishumi elinesithandathu lobubanzi kunye nobude (5/8 intshi yinguqu esuka ku-"0x" ukuya ku-"xx"), ngelixa kumanqina axande, inani lokuqala lisetyenziselwa ukumela isibhozo se ububanzi.ikota, idijithi yesibini imele ikota yobude.Kukho izinto ezimbalwa ezingaphandle kule nkqubo, ezifana ne-1¼” x 1½” isiphatho, esebenzisa igama elithi 91. Inkqubo yemetric isebenzisa amanani amabini ubude nobubanzi.(oluphi ulandelelwano.) Ngaloo ndlela, i-blade enguxande eyi-15 mm ukuphakama kunye ne-5 mm ububanzi iya kuba nenombolo ye-1505.
Amacandelo VIII kunye ne-IX nawo ahluke phakathi kweeyunithi ze-imperial kunye ne-metric.Kwinkqubo yobukhosi, icandelo lesi-8 lijongene nemilinganiselo yokufaka, kwaye icandelo lesi-9 lithetha ngobuso nobude besixhobo.Ubungakanani be-blade bunqunywe ngubukhulu besangqa esibhaliweyo, ngokunyuka kweyesibhozo ye-intshi.Ubude besiphelo kunye nesixhobo buboniswa ngoonobumba: AG kwiisayizi ezamkelekileyo zangasemva nezokugqibela zesixhobo, kunye ne-MU (ngaphandle kwe-O okanye i-Q) kwiisayizi ezamkelekileyo zangaphambili nezokugqibela.Kwi-metric system, inxalenye yesi-8 ibhekisela kubude besixhobo, kwaye inxalenye ye-9 ibhekisela kubukhulu be-blade.Ubude besixhobo buboniswa ngoonobumba, ngelixa uxande kunye nobukhulu bokufaka iparalelogram, amanani asetyenziswa ukubonisa ubude bowona mgca wokusika omde kwiimilimitha, ukungahoywa kweedesimali kunye namadijithi omnye andulelwe nguziro.Ezinye iifom zisebenzisa ubude becala kwiimilimitha (idayamitha yencakuba engqukuva) kwaye zikwangazihoyi iidesimali kunye nesimaphambili samadijithi omnye ezinoziro.
Inkqubo yemetriki isebenzisa icandelo leshumi kunye nelokugqibela, elibandakanya izikhundla zezibiyeli ezifanelekileyo kunye nokunyamezela kwe-± 0.08mm ngasemva nasekupheleni (Q), ngaphambili nangasemva (F), nasemva, ngaphambili nasekupheleni (B).
Izixhobo zenqaku elinye zifumaneka kwiindlela ezahlukeneyo, ubungakanani kunye nemathiriyeli.Abasiki benqaku elinye banokwenziwa ngesantya esiphezulu sentsimbi, intsimbi yekhabhoni, i-cobalt alloy okanye i-carbide.Nangona kunjalo, njengoko ishishini litshintshela kwizixhobo zokuguqula ezinencapha, iindleko zezi zixhobo zabenza baphantse bangabinamsebenzi.
Izixhobo ze-Brazed-tipped-tipped zisebenzisa umzimba wezinto ezingabizi kunye nencam okanye i-blank yezinto ezibizileyo zokusika eziboshwe kwindawo yokusika.Izixhobo zengcebiso ziquka isantya esiphezulu sentsimbi, i-carbide kunye ne-cubic boron nitride.Ezi zixhobo zifumaneka ngobukhulu A ukuya ku-G, kunye ne-A, B, E, F, kunye ne-G offset styles zinokusetyenziswa njengezixhobo zokusika zesandla sasekunene okanye sasekhohlo.Kwimibhobho yesikwere, inombolo elandelayo ileta ibonisa ukuphakama okanye ububanzi bomese kwishumi elinesithandathu le-intshi.Ngeemela ze-square shank, inani lokuqala liyinani lobubanzi be-shank kwi-intshi yesibhozo ye-intshi, kwaye inombolo yesibini yinani lokuphakama kwe-shank kwikota enye ye-intshi.
I-radius ye-tip ye-brazed tipped tool ixhomekeke kubukhulu be-shank kunye nomqhubi kufuneka aqinisekise ukuba ubungakanani besixhobo bufanelekile kwiimfuno zokugqiba.
Ukukruqula kusetyenziswa ikakhulu ukugqiba imingxunya emikhulu emingxumayo kwi-castings okanye imingxuma yokugqobhoza kwi-forgings.Uninzi lwezixhobo ziyafana nezixhobo zokuguqula zangaphandle, kodwa i-angle yokusika ibaluleke kakhulu ngenxa yemicimbi yokukhutshwa kwetshiphu.
Ubungqongqo bukwabalulekile ekusebenzeni okukruqulayo.Ububanzi bombhobho kunye nesidingo sokukhutshwa okongeziweyo kuchaphazela ngokuthe ngqo ubungakanani obukhulu bebhar ekruqulayo.I-overhang yokwenyani yentsimbi yokubhongisa ibha iphindwe kane ubukhulu be-shank.Ukugqithisa lo mda kunokuchaphazela izinga lokususa isinyithi ngenxa yokulahlekelwa kokuqina kunye nethuba elikhulayo lokungcangcazela.
I-diameter, i-modulus ye-elasticity yezinto, ubude, kunye nomthwalo kwi-beam kuchaphazela ukuqina kunye nokuphambuka, kunye nobubanzi obunempembelelo enkulu, elandelwa bubude.Ukwandisa ububanzi bentonga okanye ukunciphisa ubude kuya kwandisa kakhulu ukuqina.
I-modulus ye-elasticity ixhomekeke kwizinto ezisetyenzisiweyo kwaye ayitshintshi ngenxa yonyango lokushisa.I-Steel ayizinzile kwi-30,000,000 psi, iintsimbi ezinzima zizinzile kwi-45,000,000 psi, kwaye i-carbides izinzile kwi-90,000,000 psi.
Nangona kunjalo, la manani aphakamileyo ngokuzinza, kunye nemivalo yensimbi ye-shank boring ibonelela ngokusebenza okwanelisayo kwizicelo ezininzi ukuya kwi-4: 1 L / D ratio.Imivalo edikayo ene-tungsten carbide shank iqhuba kakuhle kwi-6: 1 L / D ratio.
Imikhosi yokusika iRadial kunye ne-axial ngexesha lokudinwa kuxhomekeke kwi-angle yokuthambekela.Ukwandisa i-thrust force kwi-angle yokuphakamisa encinci kunceda ngakumbi ekunciphiseni ukungcangcazela.Njengoko i-angle ekhokelayo ikhula, amandla e-radial ayanda, kwaye i-force perpendicular ukuya kwindlela yokusika nayo iyanda, okubangela ukungcangcazela.
I-engile yokuphakamisa ecetyiswayo yolawulo lokungcangcazela komngxuma ngu-0° ukuya ku-15° (I-Imperial. I-engile yokunyuswa kwe-Metric yi-90° ukuya kuma-75°).Xa i-engile yokukhokela i-degrees ezili-15, amandla okusika i-radial aphantse aphindwe kabini kunaxa i-engile yokukhokela i-0 degrees.
Kuninzi lwemisebenzi ekruqulayo, izixhobo zokusika ezithambekele ngokufanelekileyo zikhethwa kuba zinciphisa amandla okusika.Nangona kunjalo, izixhobo ezintle zine-angle encinci yokucima, ngoko ke umqhubi kufuneka aqaphele ukuba kunokwenzeka ukuqhagamshelana phakathi kwesixhobo kunye nomsebenzi.Ukuqinisekisa ukucocwa ngokwaneleyo kubaluleke kakhulu xa imingxuma emincinci ikruqulayo.
Amandla eradial kunye ne-tangential ekukhuleni okukruqulayo njengoko i-radius yempumlo isanda, kodwa la mandla ayachatshazelwa yi-engile yokukhokela.Ubunzulu bokusikwa xa kukruqulayo kunokutshintsha olu budlelwane: ukuba ubunzulu bokusika bukhulu okanye bulingana ne-radius yekona, i-angle ekhokelayo imisela amandla e-radial.Ukuba ubunzulu bokusikwa bungaphantsi kweradiyasi yekona, ubunzulu bokusikwa ngokwawo kwandisa amandla eradial.Le ngxaki yenza ukuba kubaluleke ngakumbi kubasebenzisi ukusebenzisa irediyasi yempumlo encinci kunobunzulu bokusikwa.
