Dab tsi yog kev cai hlau qhov chaw thiab cov khoom siv? Cias muab, kev cai hlau qhov chaw thiab cov khoom yog cov hlau sib dhos ua raws li tus neeg siv khoom xav tau thiab tsim cov duab kos. Cov khoom no tuaj yeem muaj cov duab yooj yim lossis cov geometry nyuaj, thiab feem ntau yog siv los sib sau ua ke rau hauv cov tshuab loj lossis cov khoom siv. Piv nrog rau cov qauv kev cai, cov khoom siv kev cai muab kev yooj yim dua hauv kev tsim thiab kev ua haujlwm, ua tau raws li cov kev xav tau tshwj xeeb.
Cov txheej txheem hauv kev tsim cov khoom siv hlau muaj xws li machining, casting, forging, stamping, welding, thiab additive manufacturing. Machining yog ib txoj hauv kev tsim cov duab uas xav tau los ntawm kev tshem tawm cov khoom siv ntau dhau; Cov cuab yeej siv feem ntau suav nrog tshuab dhos, tshuab milling, thiab tshuab drilling. Casting cuam tshuam nrog cov hlau molten rau hauv pwm thiab cia nws txias los ua ib feem; haum rau ntau lawm. Forging deforms hlau los ntawm kev siv lub siab, ua kom nws lub zog thiab toughness; haum rau cov khoom uas raug rau siab loads. Stamping thiab welding yog cov txheej txheem ntawm kev sib koom thiab tsim cov khoom siv hlau siv cov cuab yeej siv zog thiab cua sov.
