CNC machining nws tus kheej yog kom paub automation, liberate manpower, txhim kho kev ua hauj lwm efficiency, raws li zoo raws li txhim kho qhov zoo thiab qhov tseeb ntawm lub workpiece, thiab lwm yam. Yog li yuav ua li cas los xyuas kom meej cov efficiency ntawm CNC machining? Kuv yuav teb cov lus nug hauv qab no rau koj:
Nyob rau hauv lub premise ntawm kom ntseeg tau lub du ua hauj lwm ntawm lub tshuab cuab yeej, yuav ua rau lub acceleration thiab deceleration txheej txheem lub sij hawm yog lub shortest txoj kev yog qhov zoo tshaj plaws tov los txhim kho qhov ceev ntawm CNC machining, tab sis kuj txoj kev kawm ntawm acceleration thiab deceleration yog qhov tseem ceeb tshaj plaws qhov teeb meem. .
Feem ntau hais lus, muaj ob qhov sib txawv acceleration thiab deceleration tswj schemes: ua ntej interpolation thiab tom qab interpolation pre-processing acceleration thiab deceleration tswj peb feem ntau hu rau pem hauv ntej acceleration thiab deceleration tswj, tom qab lub interpolator thiab ua ntej lub servo maub los tswj tus nqi noj ntawm lub Lub zog axis feem ntau hu ua tom qab acceleration thiab deceleration. Lub algorithm ntawm post-acceleration thiab deceleration tswj yog qhov yooj yim piv nrog rau pre-acceleration thiab deceleration, thiab nws tsis tas yuav xam lub deceleration point, tab sis lub servo nce ntawm txawv axes yog tsis zoo ib yam, uas yog ib qho yooj yim mus ua. qhov cuam tshuam ntawm qhov tseeb.
Yog li, tam sim no nyob rau hauv CNC machining feem ntau yog siv nyob rau hauv pem hauv ntej acceleration thiab deceleration tswj technology, acceleration thiab deceleration tswj txoj kev yuav summarized li saj zawg zog acceleration thiab deceleration txoj kev thiab tsoos acceleration thiab deceleration txoj kev, cov tsoos acceleration thiab deceleration txoj kev muaj trapezoidal acceleration thiab deceleration method thiab exponential acceleration thiab deceleration method thiab lwm txoj kev; flexible acceleration and deceleration method has trigonometric function acceleration and deceleration method, S-curve acceleration and deceleration method and polynomial acceleration thiab deceleration method. Cov tsoos trapezoidal thiab exponential acceleration thiab deceleration txoj kev cuam tshuam qhov smoothness ntawm kev txav vim qhov kev hloov pauv sai sai, thaum lub sij hawm yoog raws acceleration thiab deceleration txoj kev muaj kev txaus siab nyob rau hauv high-speed hardware processing vim lub nruam acceleration.
