Khoom Hardness: Cov ntaub ntawv nyuaj heev tuaj yeem ua rau lub tshuab tsis yooj yim thiab tuaj yeem ua rau cov cuab yeej hnav sai, lub neej ntev dua, thiab cov nqi siab dua.
Thaum tshav kub kub tiam: Qee cov ntaub ntawv, thaum machined, tuaj yeem tsim cov cua sov ntau dhau, ua rau thermal distortion thiab cuam tshuam qhov tseeb ntawm qhov.
Toughness: Cov khoom siv tawv thiab fiber ntau tuaj yeem ua rau muaj teeb meem nrog cov cuab yeej tawg thiab yuav xav tau cov nqi noj qeeb qeeb, uas tuaj yeem txo cov khoom lag luam.
Ua Haujlwm Hardening: Qee cov ntaub ntawv, zoo li qee hom hlau, tuaj yeem ua haujlwm hnyav, uas txhais tau tias lawv nyuaj dua li lawv tau ua. Qhov no tuaj yeem ua rau machining nyuaj dua.
Galling: Thaum ob qhov chaw nyob hauv kev sib txheeb, qee cov ntaub ntawv tuaj yeem ua rau lub qhov txhab lossis vuam ntawm qhov chaw, uas tuaj yeem ua rau cov cuab yeej thiab cov khoom puas.
Thermal Expansion: Cov ntaub ntawv nthuav dav thaum cua sov. Yog tias tsis suav rau, qhov no tuaj yeem ua rau qhov tsis raug ntawm qhov tsis raug ntawm qhov tiav.
Machineability: Tsis yog txhua yam khoom siv sib npaug yooj yim rau tshuab. Kev ua haujlwm tsis zoo tuaj yeem ua rau lub ntsej muag tsis zoo, qhov tsis raug, thiab lub sijhawm ntau lawm.
Residual Stress: Machining tuaj yeem ua rau muaj kev ntxhov siab nyob hauv cov khoom, uas tuaj yeem ua rau muaj kev sib hloov lossis distortion ntawm ntu tom qab machining.
Tshuaj Reactivity: Cov ntaub ntawv reactive tuaj yeem corrode los yog puas los ntawm cov kua txiav siv hauv machining, ua rau ib feem degradation.
Grain Structure: Cov qauv nplej ntawm cov ntaub ntawv zoo li cam khwb cia hlau tuaj yeem ua rau cov yam ntxwv tsis sib xws ntawm machining thiab tuaj yeem tsim cov txiaj ntsig nyuaj.
Warpage: Qee cov ntaub ntawv muaj feem cuam tshuam los yog sib tw tom qab kev kho cua sov lossis thaum lub sijhawm ua haujlwm, tshwj xeeb tshaj yog tias lawv tsis tau txais kev txhawb nqa zoo.
Sib tham: Kev vibrations thaum lub sij hawm machining, hu ua chatter, tuaj yeem ua rau tsis zoo ntawm qhov kawg thiab qhov tsis raug. Qee cov ntaub ntawv yuav muaj kev cuam tshuam ntau dua rau kev sib tham vim lawv cov khoom siv kho tshuab.
Tool Deflection: Machining softer cov ntaub ntawv tuaj yeem ua rau cov cuab yeej txiav kom deflect, ua rau qhov tsis raug ntawm qhov tiav.
Chip Tsim: Nyuaj hauv kev tsim cov nti tuaj yeem ua rau cov khoom tsis zoo thiab cov cuab yeej tawg. Qee cov ntaub ntawv nyuaj rau qhov no ntau dua li lwm tus.
Tus nqi khoom siv: Tus nqi ntawm cov khoom siv nws tus kheej tuaj yeem yog qhov teeb meem, tshwj xeeb tshaj yog rau kev ua haujlwm precision qhov twg me me ntawm cov khoom muaj txiaj ntsig feem ntau siv.
Environmental Considerations: Qee cov ntaub ntawv yuav muaj kev txwv ib puag ncig lossis kev txhawj xeeb pov tseg uas yuav tsum tau tswj xyuas.
Muaj: Qhov muaj thiab cov saw hlau xav tau rau qee yam khoom tuaj yeem cuam tshuam rau lub sijhawm tsim khoom thiab tus nqi.
Recycling thiab Sustainability: Kev muaj peev xwm rov ua dua tshiab lossis kev cuam tshuam ib puag ncig ntawm cov khoom siv tuaj yeem ua rau muaj kev txhawj xeeb, tshwj xeeb tshaj yog rau cov tuam txhab uas muaj lub hom phiaj sustainability.
Txhawm rau txo cov teeb meem no, nws yog ib qho tseem ceeb uas yuav tau xaiv cov khoom tsim nyog rau txoj haujlwm, suav nrog cov kev cai tshwj xeeb ntawm cov khoom thiab cov peev txheej ntawm cov txheej txheem machining. Tsis tas li ntawd, siv cov txheej txheem machining siab heev, cov cuab yeej zoo, thiab kev ua haujlwm kom zoo tuaj yeem pab kov yeej ntau yam teeb meem cuam tshuam nrog precision machining cov ntaub ntawv.
