Enye yeenzuzo eziphambili zeizixhobo zeplanethiiiseti kukukwazi kwabo ukusasaza umthwalo kwiigiya ezininzi, okukhokelela ekongezeni kokuqina kunye nokusebenza okuphuculweyo. Olu luyilo lukwabonelela ngomlinganiselo ophezulu we-torque-to-weight, okwenza kube yinto efanelekileyo kwizicelo ezifuna imveliso enamandla kwifom edibeneyo. Ukongeza, iinkqubo zegiya zeplanethi zibonelela ngezinto eziguquguqukayo ezinemilinganiselo eyahlukeneyo yegiya, evumela ukuba kube lula
Kumashishini afana noomatshini beemoto kunye noomatshini bemizi-mveliso, iiseti zegiya zeplanethi ziqhele ukusetyenziswa kuthumelo ukubonelela ngezantya ezininzi kunye nokuphatha imithwalo enzima. Ukusebenza kwabo kunye nokuqina kwabo kubenza babe lolona khetho lukhethwayo kwiinjineli ezijonge ukufikelela kulawulo oluchanekileyo lwentshukumo kunye nolawulo lwamandla. Kwabo bafuna ukuthembeka kunye nokusebenza, iinkqubo zegiya zeplanethi
Sixhotyiswe ngezixhobo zokuhlola ezikumgangatho ophezulu ezifana noomatshini wokulinganisa uBrown & Sharpe olungelelanisa ezintathu, uColin Begg P100/P65/P26 iziko lokulinganisa, isixhobo saseJamani iMarl cylindricity, umhloli wokurhabaxa waseJapan, iProfayili yeOptical, iprojekti, umatshini wokulinganisa ubude njl.njl. kuhlolwa ngokuchanekileyo nangokupheleleyo .
