CNC machining yog tsim los ntawm kev kub ceev thiab kev ua haujlwm siab. Qhov no suav nrog kev tswj ceev ntawm CNC machining. Txhawm rau kom siv tag nrho cov kev ua haujlwm zoo stroke, cov khoom txav mus los yuav tsum muaj peev xwm ua kom nrawm nrawm nrawm rau lub sijhawm luv luv thiab nres kom raug rau hauv kev kub ceev stroke. Qhov no yog vim li cas nws yog tsim nyog los tswj qhov ceev ntawm CNC machining.
Raws li lub tswv yim qhib kev tswj hwm, peb tawm tswv yim ib txoj hauv kev uas tuaj yeem ua kom nrawm thiab nrawm nrawm ntawm CNC tshuab cuab yeej raws li txhua qhov nkhaus. Txoj kev no thawb lub tsis siv neeg acceleration thiab deceleration tswj los ntawm cov tsoos taag hom mus rau lub tshiab saj zawg zog hom, thiab tshawb nrhiav ib txoj hauv kev tshiab los txhim kho cov kev ua tau zoo ntawm CNC tshuab cuab yeej.
1. Yooj yim acceleration thiab deceleration tswj
Hauv CNC machining, qhov tshwj xeeb tsis siv neeg ceev tswj kev ua haujlwm feem ntau pom tau ncaj qha los ntawm qhov program program. Nyob rau hauv txoj kev no, nws yog ib qho tsim nyog los hloov cov yam ntxwv ntawm qhov nrawm thiab nrawm ntawm lub kaw lus lossis hloov kho NC qhov kev pab cuam los ntawm kev ntxiv lossis rho tawm tswj, yog li cov neeg siv tsis tuaj yeem ua rau NC tshuab cuab yeej muaj qhov zoo tshaj plaws acceleration thiab deceleration kev ua tau zoo raws li lawv tus kheej xav. Yog li ntawd, qhov hloov pauv tau nrawm thiab nrawm tswj txoj hauv kev tau thov los ntawm peb siv lub hauv paus ntsiab lus ntawm cov ntaub ntawv, faib cov acceleration thiab deceleration tswj rau hauv ob ntu: acceleration thiab deceleration piav qhia thiab kev siv, thiab cais cov acceleration thiab deceleration piav qhia los ntawm lub system program. Nyob rau hauv NC system software, ib tug dav tswj channel ywj siab ntawm acceleration thiab deceleration database cov ntsiab lus yog tsim los rau nws tus kheej ua kom tiav cov acceleration thiab deceleration xam thiab trajectory tswj.
2. Saj zawg zog tsis siv neeg acceleration tswj
Teem lub acceleration curve, analytical curve thiab non analytical curve, thiab khaws cia ua cov qauv hauv lub tsev qiv ntawv acceleration thiab deceleration nkhaus nyob rau hauv daim ntawv ntawm ib tug xov tooj rooj.
3. Saj zawg zog tsis siv neeg deceleration tswj
Lub acceleration tswj tseem khaws cia nyob rau hauv lub acceleration thiab deceleration nkhaus tsev qiv ntawv raws li ib tug template nyob rau hauv daim ntawv ntawm ib tug xov tooj rooj. Tsim nyog tsis siv neeg acceleration thiab deceleration tswj yog ib qho tseem ceeb txuas los xyuas kom meej qhov kev ua tau zoo ntawm CNC tshuab cuab yeej. Cov tsoos tsis siv neeg acceleration thiab deceleration tswj raws li qhov nkhaus nkhaus tsis yooj yim los xyuas kom meej tias cov txheej txheem acceleration thiab deceleration yog sib xws nrog lub tshuab cuab yeej kev ua tau zoo vim tsis muaj qhov yooj, thiab nws yog ib qho nyuaj rau ua tiav qhov zoo tshaj plaws dynamic yam ntxwv ntawm lub tshuab cuab yeej. kev txav mus los.
