Indlela Yesici Sesici Sezingxenye ze-3D Model

Ngokuvela kwemodeli yokukhiqiza "yezinhlobonhlobo eziningi, encane", indlela yokuthola ulwazi lokuklanywa ngabantu ikhawulele kakhulu ukusebenza kahle komsebenzi. Abantu banethemba lokuthi ukutholwa kolwazi lokuklama kungatholakala ngokuzenzakalela ngamakhompyutha.

Ulwazi lokwakhiwa luqondiswe kakhulu ezingxenyeni futhi ikakhulu lubhekisa ebudlelwaneni obuphakathi kwezici zemishini nezici zazo zezici nezici zemishini. Ngakho-ke, inhloso yokukhishwa kwesici ukuthola i-matrix element element yokucubungula kanye ne-matrix yobudlelwano besici sokucubungula.

Enqubeni yokumodela esezingeni eliphakeme ye-3D yamanje, imibono yokuchazwa okusekelwe kusici nayo iyamukelwa. Ukufeza ukukhishwa kwesici, kuyadingeka ukuthi uchaze izici kusengaphambili. Kunezinhlobo ezimbili zezindlela zencazelo yesici:

• 1) Chaza indlela yokukhiqiza yamapharamitha wesici womkhiqizo, shayela isizukulwane semodeli ngokulawula inani lesici sepharamitha, futhi uqaphele ukukhishwa kwepharamitha lesici ngenkathi kudizayina imodeli. Laba bobabili bayaphelelisana, okubizwa ngokuthi yi-feature pre-definition, noma i-feature-based parameterization Modeling.
• 2) Sebenzisa izakhi eziyisisekelo zejiyomethri ezinjengamaphoyinti, imigqa, nezindawo zokucaca ukuze uchaze imingcele yesici. Imodeli yokwakheka nokukhishwa kwesici akuphazamisani. Ngemuva kokuthi ukwakhiwa kwemodeli kuqediwe, ukukhishwa kwesici kuqediwe ngokuhlonza ifomu lenhlangano lezinto zejometri zemodeli nokufanisa amapharamitha wesici. Yincazelo yangemuva yezici, noma ukuqashelwa kwesici.

Uma kuqhathaniswa nezindlela zokubonwa kwesici, izindlela zokumodela ze-parametric zinezinzuzo ezilandelayo:

• 1) Ukumodela kwe-Parametric akukwazi kuphela ukuqeda isici sokufaka, kepha futhi kusiza abaklami ekumodeleni okusheshayo.
• 2) Indlela yokumodela enemingcele ikhipha izici ngokunembe kakhudlwana, futhi ayibangeli ukwahlulelwa okungalungile noma ukweqiwa. Indlela yokubona isici ilungele kuphela izici ezinomehluko omkhulu, futhi izici ezinamabomu wejometri afanayo kulula ukuzidida.

Ngakho-ke, le ndatshana isuselwa kwi-Siemens NX10.0 secondary development API, futhi isebenzisa indlela yokumodela ye-parametric ukubona ukukhishwa kwesici sokucutshungulwa kwezingxenye. Njengoba ukumodela okwenziwe ngamapharamitha kuchaze amapharamitha wesici ngaphambili, inani lepharamitha lingabizwa ngqo ngegama lepharamitha ukwakha ukucubungula kwesici se-matrix.

Ngakolunye uhlangothi, inikezela abasebenzisi ngomsebenzi wokukhetha indawo yesethenjwa, engathola isethenjwa ngokukhomba indawo eyisithenjwa; isici sokunamathisela singatholakala ngaphesheya kokunamathiselwe; uhlobo olufanayo lwesici lungatholakala ngokufanisa imingcele yezici zohlobo olufanayo lwesici sokucubungula esixhunywe endaweni efanayo. Lokhu kungakha i-matrix yezici zesici.

Kubunjiniyela bangempela, izici ezifanayo ziphathwa njengesici esihlanganisiwe futhi zicutshungulwe ndawonye esinyathelweni esisodwa. Ngakho-ke, ukucubungula ngemuva kuyadingeka ngesikhathi sokukhishwa kwesici, okungukuthi, ngemuva kokukhomba izici ezifanayo, zihlanganiswa zibe isici esiyinhlanganisela. Njengoba eminye imingcele yezici ezifanayo ngaphandle kwesikhundla ifana, amapharamitha wokuma kwezici ezihlanganisiwe kufomethi yesici se-matrix amukela isikhundla sesici esiboniswe kuqala kunqubo yokumodela. Ngaphezu kwalokho, ngemuva kokuhlanganiswa, izici ezisele zokucubungula azinazo izici ezifanayo, ngakho-ke i-matrix yobudlelwano besici idinga kuphela ukugcina izimpawu ezimbili zokuqala, okungukuthi, ubuhlobo benkomba nobudlelwano bokuncika.
