Tsim rau Manufacturing (DFM): Optimizing Geometries
Ib tus neeg tsav tsheb loj tshaj plaws ntawm CNC machining nqi yog geometric complexity. Txhua qhov tshwj xeeb ntawm ib feem yuav tsum muaj cov cuab yeej txiav lub cev kom hla txoj hauv kev los ntawm cov khoom siv. Yog hais tias ib tug feature nyuaj rau ib lub cuab tam mus cuag, los yog yuav tsum tsis yog - cov cuab yeej txheem, tus nqi nce mus. Design for Manufacturing (DFM) yog kev xyaum tsim cov khoom hauv ib txoj hauv kev uas ua rau lawv yooj yim- thiab pheej yig- los tsim kom tau raws li qhov ua tau.
1. Txoj Cai Internal Radius
Ib qho kev ua yuam kev ntau tshaj plaws uas cov neeg pib ua yog tsim qhov chaw nrog cov hnab tsho hauv qab zoo kawg nkaus lossis 90-degree ntsug kaum. Vim hais tias CNC milling cov cuab yeej yog puag ncig lub tog raj kheej (xws li laum khoom), lawv ib txwm tawm tom qab lub kaum sab xis, hu ua fillet, raws li lawv txiav. Txhawm rau tshuab lub kaum ntse ntse 90-degree sab hauv, cov chaw tsim khoom yuav tsum siv cov haujlwm tshwj xeeb, qeeb, thiab kim dua lwm yam xws li Electrical Discharge Machining (EDM) lossis broaching.
Txhawm rau txo cov nqi, ib txwm tsim cov fab sab hauv nrog lub voj voog dav dav. Txawm zoo dua, ua rau lub kaum sab xis ntawm lub vojvoog me ntsis loj dua lub vojvoog ntawm cov cuab yeej txiav koj xav kom lub tshuab siv.
