Amasistimu wamagiya eplanethi anikeza ukusebenza kahle okuphezulu, ukwakheka okuhlangene, nokusabalalisa komthwalo okuhle kakhulu. Bangakwazi ukufinyelela ku-97% izinga lokudluliswa kwamandla, banikeze i-torque ephezulu ephaketheni elincane, futhi basabalalise amandla ngokulinganayo phakathi kwamagiya amaningi, okuwenza alungele ukusetshenziswa kwezimboni ezihlukahlukene.

Q2. Ngabe i-powder metallurgy izuzisa kanjani ukukhiqizwa kwamagiya eplanethi? 

I-powder metallurgy inika amandla ukukhiqizwa kwezingxenye zegiya zeplanethi ezinembayo ezinodoti omncane wezinto ezibonakalayo. Le nqubo ivumela amajiyometri ayinkimbinkimbi, iqeda ukwenziwa kwemishini yesibili, inikeza ukudambisa umsindo kwemvelo, futhi inikeza ukonga kwezindleko kuzimo zokukhiqiza zevolumu ephezulu.

Q3. Yiziphi izingxenye ezibalulekile zesistimu yegiya leplanethi? 

Isistimu yegiya leplanethi iqukethe izingxenye ezintathu eziyinhloko: igiya lelanga phakathi nendawo, amagiya amaningi eplanethi elizungezile, kanye negiya lendandatho yangaphandle. Ingxenye ngayinye idlala indima ebalulekile ekudlulisweni kwamandla nasekusabalaliseni umthwalo ngaphakathi kohlelo.

Q4. Amagiya eplanethi ahlolwa kanjani ikhwalithi nokuqina? 

Ukulawulwa kwekhwalithi yamagiya eplanethi kuhlanganisa amasu okulinganisa ukunemba, izimiso zokuhlola ukuqina, nezitifiketi zomkhakha. Amasistimu e-metrology athuthukisiwe akala amaphutha ephrofayela nokunemba kobukhulu, kuyilapho ukuhlola okuguquguqukayo kulingisa izimo zomhlaba wangempela ukubikezela ubude besikhathi bezingxenye ngokunembile.

Q5. Yikuphi ukuthuthuka kwezinto ezibonakalayo okuthuthukise ukusebenza kwegiya leplanethi? 

Intuthuko yezinto ezibonakalayo yakamuva ihlanganisa ama-alloys ensimbi asebenza kahle kakhulu, ukuhlanganiswa kwezinto eziyinhlanganisela, nobuchwepheshe bokwelapha obusezingeni eliphezulu. Lezi zinto ezintsha ziholele kumagiya eplanethi anamandla athuthukisiwe, isisindo esincishisiwe, ukumelana nokuguga okuthuthukisiwe, nokusebenza okungcono ezimeni ezimbi kakhulu.
