Ua rau Workpiece DeformationCauses ntawm Workpiece Deformation
- Imbalanced internal stresses: Cov ntaub ntawv inherently muaj internal stresses. Hlau txiav cuam tshuam qhov sib npaug ntawm cov kev ntxhov siab, ua rau deformation raws li cov khoom siv los ua kom sib npaug.
- Workpieces qauv: Workpieces nrog nqaim thiab elongated duab, raws li zoo raws li nyias phab ntsa thickness, yog nquag deformation thaum hlau txiav.
- Lwm yam tseem ceeb: Cov teeb meem ntsig txog cov khoom siv, teeb meem kev kho cua sov, tsim teeb meem, kev npaj cov txheej txheem, thiab tsis raug clamping thiab txiav txoj kev xaiv tuaj yeem ua rau cov khoom deformation.

Kev Tiv Thaiv Kev Ntsuas rau Workpiece Deformation
Pre-cut ntxhib machining los yog kev ntxhov siab nyem txiav: Ua cov machining ntxhib los yog siv cov txheej txheem kev ntxhov siab txo kev ntxhov siab yuav pab txo qis cov kev ntxhov siab nyob hauv cov khoom ua ntej xaim txiav, txo qhov kev pheej hmoo ntawm deformation.
Machining pilot qhov: Thaum txiav cov pwm convex, machining pilot qhov nyob rau hauv cov khoom ua ntej cov txheej txheem txiav tiag tiag pab tswj kev ntxhov siab thiab tiv thaiv qhib lossis kaw deformations.
Optimizing txiav txoj kev: Kev npaj cov kev txiav kom raug yog qhov tseem ceeb heev. Pib cov txheej txheem txiav nyob ze ntawm qhov kawg clamped, tso cov ntu ntu ntawm qhov kawg ntawm txoj kev, thiab qhov chaw nres cov ntsiab lus ze rau qhov kawg clamped kom txo qis deformation los ntawm kev txiav tsis raug.
Ntau qhov hlais: Yog hais tias lub workpiece deformation txuas ntxiv txawm tias muaj kev tiv thaiv kev tiv thaiv, kev siv ntau qhov kev txiav tuaj yeem ua tau zoo. Txoj hauv kev no suav nrog kev faib cov txheej txheem txiav rau ntau theem kom ua tiav qhov xav tau qhov tseeb thaum txo qis deformation los ntawm kev ntxhov siab sab hauv.
Incorporating ntau tuav cov ntsiab lus: Rau qhov loj thiab nyuaj-zoo li tus workpieces, koom nrog ntau cov ntsiab lus tuav los ntawm kev ntxiv ob peb lub ntsiab lus pib thoob plaws hauv txoj kev txiav pab faib cov khoom txiav thiab txo qis deformation.Pre-cut ntxhib machining los yog kev ntxhov siab nyem txiav: Ua cov machining ntxhib lossis siv cov txheej txheem kev ntxhov siab. pab alleviate residual stresses nyob rau hauv cov khoom ua ntej xaim txiav, txo qhov zoo ntawm deformation.
Machining pilot qhov: Thaum txiav convex pwm, machining pilot qhov nyob rau hauv cov khoom ua ntej qhov tseeb txiav txheej txheem pab tswj kev ntxhov siab tshuav thiab tiv thaiv qhib los yog kaw deformations.
Optimizing txiav txoj kev: Kev npaj cov kev txiav kom raug yog qhov tseem ceeb heev. Pib cov txheej txheem txiav nyob ze ntawm qhov kawg clamped, tso cov ntu ntu ntawm qhov kawg ntawm txoj kev, thiab qhov chaw nres cov ntsiab lus ze rau qhov kawg clamped kom txo qis deformation los ntawm kev txiav tsis raug.

Workpiece deformation hauv cov txheej txheem hlau txiav tuaj yeem tswj tau zoo los ntawm kev sib xyaw ua ke ntawm kev tiv thaiv. Los ntawm kev hais txog cov hauv paus ntsiab lus xws li kev tsis sib haum xeeb hauv kev ntxhov siab, txhim kho txoj hauv kev zoo, thiab siv cov txheej txheem kev ntxhov siab, cov tuam txhab tuaj yeem txo qhov kev ua haujlwm deformation thiab xyuas kom meej qhov ntev hauv lawv cov kev ua haujlwm hlau. Kev ua raws li cov tswv yim no tsis yog tsuas yog txhim kho tag nrho cov khoom zoo kawg nkaus xwb tab sis kuj txhim kho kev ua tau zoo thiab kev ntseeg siab ntawm cov txheej txheem hlau txiav.Workpiece deformation hauv cov txheej txheem hlau txiav tuaj yeem tswj tau zoo los ntawm kev sib xyaw ua ke ntawm kev tiv thaiv kev tiv thaiv.
