Kwihlabathi lokwenziwa kwezinto ngokuchanekileyo, ukusuka ekuvelisweni kwee-semiconductor ukuya ekuchwethezeni izinto ze-aerospace, umahluko phakathi kwempumelelo nokungaphumeleli udla ngokulinganiswa ngee-microns. Nangona ingqalelo eninzi inikwa kubuchule besixhobo somatshini ngokwaso—i-spindle, i-controller, ii-servo motors—isiseko apho ezi matshini zisekelwe khona sihlala singanakwa. Sekunjalo, sisiseko esilawula uzinzo olupheleleyo lwenkqubo.
Kangangamashumi eminyaka, intsimbi kunye nesinyithi esityhidiweyo beziyindlela eqhelekileyo yokubeka iziseko zoomatshini. Nangona kunjalo, njengoko iimfuno zokunyamezelana ziqina kwaye izinto eziguquguqukayo kwindalo ziba nzima ukuzilawula, eli shishini libona utshintsho olukhulu oluya kwi-granite yendalo. Eli nqaku liphonononga ifiziksi engasemva kolu tshintsho, lihlalutya isizathu sokuba iziseko zoomatshini be-granite zibe lukhetho olungenakuxoxiswana ngalo lwesiseko sezixhobo ezichanekileyo zokwenyani.
I-Physics of Stability: Ii-Coefficients zoKwandiswa koBushushu
Utshaba oluphambili lwezixhobo ezichanekileyo kukungaguquguquki kobushushu. Zonke izinto ziyanda xa zishushu kwaye ziyancipha xa zipholile. Kwisiseko somatshini, notshintsho oluncinci ngobukhulu lunokukhokelela kwiimpazamo ezinkulu zejiyometri kwindawo yokusebenza.
Umngeni weNsimbi
Intsimbi yinto eqinileyo enamandla okutsalwa, kodwa inengxaki yokwanda kobushushu obuphezulu (malunga ne-11.5 ukuya kwi-12.0 × 10⁻⁶/°C). Kwimeko eqhelekileyo yokusebenzela apho amaqondo obushushu anokutshintshatshintsha ngamadigri aliqela emini ngenxa yokukhanya kwelanga, imijikelo ye-HVAC, okanye oomatshini abakufutshane, isiseko sentsimbi siya kutshintsha imo ngokwasemzimbeni. Le nto, eyaziwa ngokuba yi-"thermal drift," inyanzela umatshini ukuba uhlale ulungisa, nto leyo edla ngokukhokelela kwiindawo ezilahliweyo okanye isidingo semijikelo emide yokufudumeza.
