Njira yowerengera yotsika d-ges-Td ndiye kukula koyambira kwa mainchesi a ulusi - kupatuka kwa datum - kulolerana.
Chitsanzo: M8 ulusi wakunja 6g giredi lalikulu m'mimba mwake chapamwamba malire mtengo φ8-0.028=φ7.972.
M'munsi malire mtengoφ8-0.028-0.212=φ7.76
Zindikirani: ① Kukula kwakukulu kwa ulusi kumatsimikiziridwa ndi kukula kwa ndodo yopukutidwa komanso kuchuluka kwa mawonekedwe a ulusi wa ulusi wogudubuza / wodzigudubuza, ndipo mtengo wake umasiyana mosiyana ndi kukula kwake kwa ulusi kutengera yemweyo akusowekapo ndi ulusi processing zida. Ndiko kuti, ngati chigawo chapakati chili chaching'ono, chiwombankhanga chachikulu chidzakhala chachikulu, ndipo mosiyana ngati m'mimba mwake muli wamkulu, m'mimba mwake waukulu udzakhala wochepa.
② Pazigawo zomwe zimafuna chithandizo cha kutentha ndi chithandizo chapamwamba, poganizira za kukonza, ulusi wapakati uyenera kuyendetsedwa kuti ukhale pamwamba pa malire apansi a kalasi ya 6h kuphatikizapo 0.04mm panthawi yopanga kwenikweni. Mwachitsanzo, ulusi wakunja wa M8 ukugwedeza (kugudubuza) Kuzama kwakukulu kwa waya kuyenera kukhala pamwamba pa φ7.83 ndi pansi pa 7.95.
4. Kuwerengera ndi kulolerana kwa ulusi wamkati mkati
a. Kuwerengera kukula kwa ulusi wamkati kakang'ono (D1)
Kukula kwa ulusi = kukula kwa ulusi wamkati - phula × kokwanira
Chitsanzo: Kuzama kwakukulu kwa ulusi wamkati M8 ndi 8-1.25 × 1.0825 = 6.646875≈6.647
b. Kuwerengera kwa kulolerana kwazing'ono (kutengera phula) ndi mtengo wapakati wa 6H wamkati

P2.0 +0.375 P2.5 +0.48
M'munsi malire apatuka chilinganizo cha 6H kalasi yamkati ulusi D1 + HE1 ndi yoyambira kukula kwa ulusi wamkati m'mimba mwake yaying'ono + kupatuka.
Zindikirani: Mtengo wotsikirapo wa 6H ndi "0"
Kuwerengera kwa mtengo wapamwamba wa kalasi ya 6H ulusi wamkati ndi = D1 + HE1 + TD1, yomwe ndi kukula kwake kwa kagawo kakang'ono ka ulusi wamkati + kupatuka + kulekerera.
Chitsanzo: Malire apamwamba a ulusi wamkati wa 6H grade M8 ndi 6.647 +0 = 6.647
Malire apansi ang'onoang'ono a 6H kalasi ya M8 mkati ulusi ndi 6.647 + 0 + 0.265 = 6.912
c. Kuwerengera kwapatuka koyambira kagawo kakang'ono ka ulusi wamkati 6G kalasi (kutengera phula) ndi mtengo waung'ono
P0.8 +0.024 P1.0 +0.026 P1.25 +0.028 P1.5 +0.032 P1.75 +0.034
P2.0 +0.038 P2.5 +0.042
Njira yochepetsera malire ang'onoang'ono a 6G kalasi yamkati ulusi = D1 + GE1, yomwe ndi kukula kwake kwa ulusi wamkati + kupatuka.
Chitsanzo: Malire otsika ang'onoang'ono a 6G grade M8 ulusi wamkati ndi 6.647 + 0.028 = 6.675
The chapamwamba malire mtengo chilinganizo cha 6G kalasi M8 mkati ulusi awiri D1+GE1+TD1 ndi zofunika kukula kwa mkati ulusi + kupatuka + kulolerana.
Chitsanzo: Malire apamwamba a ulusi wamkati wa 6G grade M8 ndi 6.647 + 0.028 + 0.265 = 6.94
Zindikirani: ① Kutalika kwa ulusi wamkati kumagwirizana mwachindunji ndi nthawi yonyamula katundu ya ulusi wamkati, kotero kuyenera kukhala mkati mwa malire apamwamba a giredi 6H panthawi yopanga yopanda kanthu.
② Pakukonza ulusi wamkati, kucheperako kwake kwa ulusi wamkati kumakhala ndi mphamvu pakugwiritsa ntchito bwino kwa chida chopangira makina - mpopi. Malinga ndi kagwiritsidwe ntchito, kung'ung'udza kwake kumakhala bwinoko, koma poganizira mozama, m'mimba mwake yaying'ono imagwiritsidwa ntchito. Ngati ndi chitsulo chosungunula kapena gawo la aluminiyamu, malire apansi mpaka malire apakati ang'onoang'ono ayenera kugwiritsidwa ntchito.
③ Kuzama pang'ono kwa ulusi wamkati 6G kumatha kukhazikitsidwa ngati 6H popanga zopanda kanthu. Mlingo wolondola makamaka umayang'ana momwe ulusiwo umakhalira. Chifukwa chake, kutalika kwapampopi kokha kumaganiziridwa panthawi yokonza ulusi popanda kuganizira kukula kwa dzenje lowala.
5. Njira yowerengera ya njira imodzi yolozera mutu
Njira yowerengera ya njira yolondolera imodzi: n=40/Z
n: ndi chiwerengero cha zosintha zomwe mutu wogawa uyenera kutembenuka
Z: gawo lofanana la workpiece
40: Nambala yokhazikika ya mutu wogawa
Chitsanzo: Kuwerengetsera mphero ya makona atatu
Lowetsani mu fomula: n=40/6
Kuwerengera: ① Sambani kagawo kakang'ono: Pezani chogawa chaching'ono 2 ndikuchigawa, ndiko kuti, gawani nambala ndi denominator ndi 2 nthawi yomweyo kuti mupeze 20/3. Pamene kuchepetsa kagawo kakang'ono, magawo ake ofanana amakhalabe osasintha.
② Werengetsani gawolo: Pakadali pano, zimatengera mayendedwe a manambala ndi denominator; ngati manambala ndi denominator ndi zazikulu, werengerani.
20÷3=6(2/3) ndi mtengo wa n, ndiko kuti, mutu wogawa uyenera kutembenuzidwa nthawi 6(2/3). Panthawiyi, kagawo kakang'ono kakhala nambala yosakanikirana; gawo lalikulu la nambala yosakanikirana, 6, ndi nambala yogawa Mutu uyenera kutembenuza 6 mozungulira. Gawo la 2/3 lokhala ndi kachigawo kakang'ono likhoza kukhala 2/3 la kutembenuka kumodzi, ndipo liyenera kuwerengedwanso panthawiyi.
③ Kuwerengera kwa kusankha kwa mbale yolozera: Kuwerengera kwa bwalo lochepera limodzi kuyenera kuzindikirika mothandizidwa ndi mbale yolozera pamutu wolozera. Gawo loyamba pakuwerengera ndikukulitsa gawo 2/3 nthawi yomweyo. Mwachitsanzo: ngati gawolo likukulitsidwa nthawi 14 nthawi imodzi, gawolo ndi 28/42; ngati ikukulitsidwa nthawi 10 nthawi imodzi, mphambu ndi 20/30; ngati ikulitsidwa nthawi 13 nthawi imodzi, chiwerengerocho ndi 26/39 ... Kuchulukitsa kwachipata chogawanitsa kuyenera kusankhidwa malinga ndi chiwerengero cha mabowo mu mbale yolozera.
Panthawi imeneyi, muyenera kusamala:
①Nambala ya mabowo osankhidwa pa indexing plate iyenera kugawikana ndi denominator 3. Mwachitsanzo, mu chitsanzo chapitachi, mabowo 42 ndi 14 nthawi 3, mabowo 30 ndi 10 kuchulukitsa 3, 39 ndi 13 nthawi 3 ...
② Kukula kwa kachigawo kakang'ono kuyenera kukhala kotero kuti nambala ndi denominator zikukulitsidwa nthawi imodzi ndipo magawo awo ofanana amakhalabe osasinthika, monga mu chitsanzo.
28/42=2/3×14=(2×14)/(3×14); 20/30=2/3×10=(2×10)/(3×10);
26/39=2/3×13=(2×13)/(3×13)
Denominator 42 ya 28/42 imayikidwa pogwiritsa ntchito mabowo 42 a chiwerengero cha chiwerengero; Nambala 28 ili patsogolo pa dzenje la gudumu lakumtunda ndikuzungulira pa dzenje la 28, ndiye kuti, dzenje la 29 ndiye bowo la gudumu lapano, ndipo 20/30 ili pa 30 Mbale yolozera dzenje imatembenuzidwira kutsogolo. ndipo dzenje la 10 kapena dzenje la 11 ndilo dzenje loyikapo epicycle. 26/39 ndiye bowo loyika epicycle pambuyo poti mbale yolozera mabowo 39 itembenuzidwe patsogolo ndipo dzenje la 26 ndi dzenje la 27.
