Indlela yokuthuthukisa ukunemba kwesikhunta sepulasitiki?
1. Ikhwalithi yokucubungula isikhunta ihlanganisa ukunemba kokucubungula kanye nekhwalithi ephezulu
Ukunemba komshini yizinga lokuvumelana phakathi kosayizi wangempela, umumo kanye nokuma kwendawo engaphezulu yengxenye eyenziwe ngomshini kanye nemingcele yejiyomethri efanelekile edingwa umdwebo.
Ipharamitha yejiyomethri efanelekile, ngosayizi, usayizi ophakathi; Ngejometri engaphezulu, iyindilinga ngokuphelele, isilinda, indiza, ikhoni kanye nomugqa oqondile. Ngokuma okuhlangene phakathi kwezindawo, ihambisana ngokuphelele, iqondile, i-coaxial, i-symmetric, njll. Ukuchezuka phakathi kwamapharamitha wangempela wejiyomethri kanye namapharamitha afanelekile wejiyomethri wengxenye kubizwa ngokuthi iphutha lomshini.
Ukunemba komshini kanye nephutha lomshini womabili amagama asetshenziselwa ukuhlola amapharamitha ejiyomethri ezindawo ezinomshini. Ukunemba komshini kukalwa ngebanga lokubekezelelana, uma lincane inani lebanga, kuphakama ukunemba; Iphutha lomshini livezwa ngenani lenombolo, futhi inani lenombolo likhulu, iphutha likhulu. Ukunemba okuphezulu kokucubungula kusho iphutha elincane lokucubungula, futhi ngokuphambene nalokho.
Imingcele yangempela etholwe nganoma iyiphi indlela yokucubungula ngeke inembile ngokuphelele, kusukela emsebenzini wengxenye, inqobo nje uma iphutha lokucubungula lingaphakathi kokubekezelelana okudingekayo ngomdwebo wengxenye, ukunemba kokucubungula kubhekwa njengokuqinisekiswa.
Izinga lomshini lincike kwikhwalithi yomshini wezingxenye kanye nekhwalithi yomhlangano womshini. Ikhwalithi yomshini wezingxenye ihlanganisa ukunemba kwemishini yezingxenye kanye nekhwalithi ephezulu yezingxenye ezimbili. Ukunemba komshini kubhekisela ezingeni lapho imingcele yejiyomethri yangempela (usayizi, umumo kanye nendawo) yezingxenye ngemva kokucubungula ihambisana nemingcele efanelekile yejometri.
Umehluko phakathi kwabo ubizwa ngephutha lomshini. Usayizi wephutha lomshini ubonisa ukunemba komshini. Uma iphutha lilikhulu, kuncipha ukunemba kwemishini, futhi iphutha lincane, kukhulisa ukunemba komshini.
2. Izici eziyinhloko ezithinta ukunemba kokucubungula
2.1 Ukunemba kobukhulu
Isho izinga lokuvumelana phakathi kosayizi wangempela wengxenye emshinini kanye nendawo yokubekezelela yendawo yosayizi wengxenye. Ukunemba kwe-Dimensional kulawulwa ukubekezelela kwe-dimensional. Ukubekezelela i-Dimensional ukuhluka okuvumelekile kusayizi wengxenye ngesikhathi sokusika. Endabeni yosayizi ofanayo oyisisekelo, kuncane ukubekezelela kobukhulu futhi kukhulisa ukunemba kobukhulu.
2.2 Ukunemba komumo
Isho izinga lokuvumelana phakathi kwejiyomethri yangempela yengxenye eyenziwe ngomshini kanye nejometri efanelekile. Kunezinto eziyisi-6 zokuhlola ukunemba komumo, njengokuqondile, ukucaba, ukuzungeza, isilinda kanye nephrofayili yomugqa. Ukunemba komumo kulawulwa ukubekezelelana komumo, futhi ukubekezelelana komumo ngamunye kuhlukaniswe ngamaleveli okunemba angu-12 ngaphandle kwamazinga okunemba angu-13 okuzungeza kanye necylindricity. I-Level 1 iphezulu futhi ileveli ye-12 iphansi kakhulu.
2.3 Ukunemba kwesikhundla
Isho umehluko wokunemba kwendawo yangempela phakathi kwezindawo ezifanele zezingxenye zomshini. Kunezinto eziyisishiyagalombili zokuhlola ukunemba kwesikhundla, njengokufana, i-perpendicularity, ukuthambekela, i-coaxiality, i-symmetry, indawo, ukuphuma okuyindilinga kanye nokuphuma okugcwele. Ukunemba kwesikhundla kulawulwa ukubekezelelana kwesikhundla, okubuye kuhlukaniswe ngamaleveli okunemba ayi-12.
