Electrical discharge machining (EDM) yog ib hom hluav taws xob paug machining, tshwj xeeb tshaj yog cov txheej txheem tsim lub qhov. EDM tshem tawm cov khoom siv los ntawm kev siv cov pa tawm hauv cov kua nruab nrab kom ua rau cov khoom siv hluav taws xob. Nws cov thev naus laus zis tseem ceeb nyob hauv kev siv lub hollow tubular electrode (feem ntau yog tooj dag lossis tooj liab raj) los ua cov pa taws tawm ntawm lub workpiece kom tshem tawm cov hlau. Tsis zoo li cov xaim EDM lossis cov txheej txheem tsim, cov electrode yog hollow, thiab lub tshuab nruab nrab (feem ntau yog dej) dhau los ntawm lub qhov me me hauv nruab nrab ntawm lub raj electrode, ua haujlwm kom txias thiab ntws tawm cov khoom yaig.
Raws li lub hauv paus ntsiab lus no, EDM thev naus laus zis muaj cov yam ntxwv hauv qab no: nws tuaj yeem siv lub siab -hardness, siab - lub zog, thiab siab - toughness conductive khoom; nws tsis muaj qhov tseem ceeb macroscopic mechanical quab yuam thaum lub sij hawm machining, ua rau nws haum rau tsawg- rigidity workpieces thiab microstructure machining; Nws tuaj yeem nkag mus ncaj qha rau hauv qhov chaw lossis qhov chaw nkhaus thiab tuaj yeem siv los tshem tawm cov khoom tawg thiab cov kais dej los ntawm cov khoom ua haujlwm yam tsis muaj kev puas tsuaj rau lub qhov qub; qhov siab tshaj plaws qhov tob - rau - txoj kab uas hla tuaj yeem ncav cuag 300: 1. High-ceev me- qhov machining yog ib qho tseem ceeb ntawm txoj kev loj hlob ntawm hluav taws xob tawm machining (EDM) los daws cov teeb meem xws li qhov tob loj - mus rau - txoj kab uas hla piv thiab tshem tawm cov nti nyuaj. Micro- hluav taws xob tso tawm machining (MED) yog kev txiav- ntug kev taw qhia, suav nrog cov thev naus laus zis tseem ceeb xws li micro-feed mechanisms, micro-machining servo systems, micro-sensors, thiab kev tsim cov electrodes me me.
