Koj puas nkag siab txog daim ntawv thov ntawm geometric kam rau ua hauv CNC machining?
Qhov tshwj xeeb ntawm geometric tolerances yog ib qho tseem ceeb ntawm CNC machining, vim nws ua kom muaj tseeb ntawm cov khoom.Geometric kam rau ua yog cov variations uas yuav ua tau nyob rau hauv qhov loj, zoo, orientation thiab qhov chaw ntawm ib tug feature ntawm ib daim.Cov kev hloov pauv no tseem ceeb heev rau kev ua haujlwm ntawm qhov chaw.
Geometric kam rau ua yog siv hauv CNC machining rau ntau yam kev siv.
Dimensional tswj:
Geometric tolerences tso cai rau kev tswj xyuas qhov loj thiab qhov loj me ntawm cov yam ntxwv ua haujlwm.Nws ua kom ntseeg tau tias txhua qhov chaw tau zoo sib xws thiab ua tau raws li lawv qhov kev xav tau.
Daim Ntawv Tswj:
Geometric Tolerances xyuas kom meej tias cov duab xav tau thiab contour tiav rau cov yam ntxwv ua haujlwm.Nws yog ib qho tseem ceeb rau cov khoom uas yuav tsum tau sib sau ua ke, los yog muaj cov kev cai tshwj xeeb mating.
Orientation Control:
Geometric tolerences yog siv rau kev tswj ntawm lub kaum sab xis ntawm cov nta xws li qhov, qhov thiab qhov chaw.Nws yog ib qho tseem ceeb tshwj xeeb tshaj yog rau cov khoom uas xav tau kev sib raug zoo los yog yuav tsum haum rau lwm qhov chaw.
Geometric Tolerances:
Geometric tolerences yog qhov sib txawv uas tuaj yeem ua rau hauv txoj haujlwm ntawm cov yam ntxwv ntawm ib yam khoom.Nws ua kom ntseeg tau tias cov yam ntxwv tseem ceeb ntawm ib feem tau muab tso rau hauv kev sib raug zoo rau ib leeg, ua kom muaj kev ua haujlwm zoo thiab sib dhos.
Tswj profile:
Geometric Tolerances yog siv los tswj tag nrho cov duab thiab profile rau cov yam ntxwv nyuaj xws li curves, contours thiab nto.Qhov no ua kom paub tseeb tias cov khoom siv ua tau raws li qhov yuav tsum tau ua ntawm qhov profile.
Control ntawm Concentricity & Symmetry:
Geometric tolerances ua lub luag haujlwm tseem ceeb hauv kev ua tiav qhov sib npaug & sib luag rau cov yam ntxwv ua haujlwm.Nws yog ib qho tseem ceeb tshwj xeeb tshaj yog thaum aligning rotating Cheebtsam xws li shafts, gears thiab bearings.
Kev tswj kev khiav hauj lwm:
Geometric tolerances qhia qhov kev tso cai hloov pauv hauv qhov ncaj thiab voj voog ntawm kev sib hloovcnc tig part.Nws yog tsim los xyuas kom meej kev ua haujlwm du thiab txo kev vibrations thiab yuam kev.
Yog tias peb tsis nkag siab txog geometric tolerances ntawm cov duab kos hauv kev tsim khoom, tom qab ntawd kev txheeb xyuas kev ua haujlwm yuav raug kaw thiab cov txiaj ntsig ntawm kev ua haujlwm tseem tuaj yeem loj heev.Cov lus no muaj 14-khoom thoob ntiaj teb tus qauv geometric kam rau ua cim.
