Comprehensive Analysis of Machining Center NC Issues
I. Txhais thiab Scope ntawm Machining Center NC Teeb meem
Thaum lub chaw machining qhov chaw Numerical Control (NC) system ua haujlwm tsis zoo, nws feem ntau tshwm sim raws li kev cuam tshuam kev ua haujlwm, txo qhov raug machining, cov khoom siv tswb, lossis ua tiav qhov kaw lus. Cov teeb meem zoo li no tuaj yeem tshwm sim los ntawm software (xws li, programming yuam kev, teeb tsa tsis raug) lossis kho vajtse (xws li tsav tsis ua haujlwm, sensor malfunctions). Piv txwv li, ib lub tuam txhab tau raug kev txom nyem loj ntawm cov khoom seem muaj nqis ntau lab vim NC system nco kev noj nyiaj txiag, qhia txog qhov tseem ceeb rau kev kuaj mob raws sij hawm. Ntawm nws qhov tseem ceeb, NC qhov teeb meem cuam tshuam nrog kev ua tsis tiav hauv kev sib koom tes ntawm NC system thiab cov khoom siv tshuab, feem ntau tshwm sim los ntawm kev hloov pauv ntawm lub zog, kev cuam tshuam ib puag ncig, lossis kev ua haujlwm yuam kev.
II. Common NC Issue Types and Diagnostic Techniques
- Program-txog teeb meem: yuam kev nyob rau hauv G- sau code los yog tsis raug post- processor settings tuaj yeem ua rau cov cuab yeej txawv txav. Txoj kev sib txawv tuaj yeem tshawb pom thaum ntxov siv cov haujlwm simulation.
- Hardware faults: Servo motor overheating thiab encoder teeb liab poob yog cov teeb meem kho vajtse. Kev ruaj ntseg hluav taws xob tuaj yeem kuaj xyuas nrog multimeter, thaum lub teeb liab waveforms tuaj yeem pom ntawm oscilloscope rau kev ua txhaum sai sai.
- Kev sib txuas lus tsis txaus ntseeg: Kev cuam tshuam hauv cov ntaub ntawv xa tawm ntawm NC thiab PLC feem ntau tshwm sim los ntawm xoob xaim lossis IP chaw nyob tsis sib haum. Txoj kev daws teeb meem segmented yog pom zoo: ua ntej txheeb xyuas cov xwm txheej ntawm lub network module qhia teeb, tom qab ntawd xyuas cov txheej txheem kev teeb tsa.
Ib txoj kev tshawb fawb txog kev saib xyuas tau qhia tias los ntawm kev sib piv cov cav tsis sib xws los ntawm lub tshuab ua haujlwm nrog cov uas muaj qhov yuam kev, cov kws tshaj lij nrhiav pom Z-axis acceleration parameter tau hloov kho tsis raug; kho nws rov qab machining raug, underscoring qhov tseem ceeb ntawm parameter cov ntaub ntawv - khaws cia.
III. Peb lub tswv yim zoo los tiv thaiv NC teeb meem
- Tsim cov ntaub ntawv kev noj qab haus huv cov cuab yeej: Sau txhua hnub machining tsis txwv, tswb codes, thiab kev saib xyuas keeb kwm los tsim cov ntaub ntawv - tsav tsheb txij nkawm. Ib lub tuam txhab tau ua tiav kev kwv yees spindle bearing hnav txaus ntshai ob lub lis piam ua ntej los ntawm kev txheeb xyuas 3,000 cov ntaub ntawv keeb kwm nkag.
- Ua ib tug tier tu system:
Txhua hnub: Ntxuav cov kiv cua txias, xyuas cov roj qib.
Txhua lub lim tiam: Thaub qab qhov system parameters, calibrate linear scales.
Txhua hli: Hloov hydraulic roj lim ntsiab, sim grounding kuj.
- Tsim kom muaj ntau- pab neeg ua haujlwm txawj ua haujlwm: Yuav tsum muaj cov neeg ua haujlwm kho tshuab kom paub cov kev txawj ua haujlwm yooj yim thiab cov programmers kom nkag siab txog cov qauv kev sib kis. Los ntawm hla- kev cob qhia, ib lub rooj cob qhia txo qhov nruab nrab NC qhov teeb meem lub sij hawm daws teeb meem los ntawm 4 teev mus rau 1.2 teev.
