Yooj yim muab, macro yog siv cov qauv los ua cov khoom. Piv txwv li, ellipse, yog tias tsis muaj macro, peb yuav tsum xam cov ntsiab lus ntawm qhov nkhaus taw tes los ntawm taw tes, thiab maj mam kwv yees nws nrog txoj kab ncaj nraim. Yog hais tias nws yog ib tug workpiece nrog siab smoothness yuav tsum, ces peb yuav tsum tau xam ntau cov ntsiab lus, tab sis tom qab siv lub macro, peb muab lub ellipse formula rau hauv lub system thiab ces peb muab lub Z kev koom tes thiab ntxiv ib tug npaum li cas txhua zaus, ces tus macro yuav cia li suav X kev tswj hwm thiab ua kev txiav. Qhov tseeb, lub luag haujlwm tseem ceeb ntawm macro hauv qhov program yog xam.

Hais txog macro programs
Dab tsi yog macro program
Thaum programming, peb yuav khaws cov lus qhia uas tuaj yeem ua tiav qee yam haujlwm rau hauv lub cim xeeb zoo li lub subroutine, thiab hu rau lawv nrog cov lus qhia dav dav. Thaum siv nws, peb tsuas yog yuav tsum tau muab cov lus qhia dav dav no kom ua tiav cov haujlwm khaws cia Cov lus qhia no yog hu ua tus neeg siv macro program lub cev, lossis macro program luv luv.
Cov lus txib dav dav no hu ua tus neeg siv macro hu hais kom ua. Thaum programming, programmers tsuas yog yuav tsum nco txog cov lus qhia macro tab sis tsis yog macro programs.
Thaum twg macro programming yuav siv?
1) Manually programmed ua qauv nkhaus (xws li yooj yim, ceev cov tswv yim)
2) Kev txiav tsis tu ncua (raws li kev txiav module)
3) Inter-program tswj (kev pab cuam teem sijhawm)
4) Kev tswj cov cuab yeej (cov cuab yeej hnav)
5) Tsis siv neeg ntsuas (hauv tshuab sojntsuam)
Qhov txawv ntawm macro program thiab ib txwm ua haujlwm
1) Hauv macro program lub cev, tuaj yeem siv qhov sib txawv, qhov tseem ceeb tuaj yeem raug xa mus rau qhov sib txawv, suav tuaj yeem ua tiav ntawm qhov sib txawv, thiab cov kev pabcuam tuaj yeem dhia.
2) Hauv cov kev pab cuam zoo tib yam, tsuas yog qhov tsis tu ncua tuaj yeem teev tau, thiab kev ua haujlwm ntawm qhov tsis tuaj yeem ua tsis tau. Cov kev pab cuam tsuas tuaj yeem ua tiav ua ntu zus thiab tsis tuaj yeem dhia, yog li cov haujlwm raug kho thiab hloov tsis tau.
3) Kev ua haujlwm macro yog qhov tshwj xeeb rau cov neeg siv los txhim kho kev ua haujlwm ntawm CNC tshuab cuab yeej, thiab kev siv cov macro program hauv kev ua haujlwm zoo sib xws yuav ua tiav ob zaug qhov txiaj ntsig nrog ib nrab ntawm kev siv zog.

Kev hloov pauv thiab hom ntawm macro programs
Cov yam ntxwv ntawm macro programs
Qhov kev pabcuam macro tuaj yeem siv qhov sib txawv, thiab qhov sib txawv tuaj yeem siv los ua cov haujlwm sib xws; tus nqi sib txawv tiag tiag tuaj yeem muab rau qhov sib txawv los ntawm kev qhia macro program.
Peb Hom Variables
Daim ntawv sawv cev sib txawv ntawm CNC system yog "#" ua raws li 1 txog 4 tus lej, thiab muaj peb hom kev sib txawv:
(1) Cov hloov pauv hauv zos: # 1 ~ # 33 yog cov hloov pauv siv hauv zos hauv macro program, uas yog siv rau kev hloov pauv hloov pauv ywj pheej.
(2) Kev hloov pauv ntau: tus neeg siv tuaj yeem siv nws dawb, thiab nws yog ib txwm muaj rau txhua qhov subroutine thiab txhua qhov kev pabcuam macro hu ua los ntawm cov haujlwm tseem ceeb. # 100 ~ # 149, tom qab kaw lub hwj chim, tag nrho cov nqi sib txawv yuav raug tshem tawm, thaum # 500 ~ # 509, tom qab kaw lub hwj chim, qhov sib txawv ntawm qhov tseem ceeb tuaj yeem txuag tau.
(3) Kev sib txawv ntawm qhov system: Nws tau txhais los ntawm kev ua raws li 4 tus lej, nws tuaj yeem tau txais kev nyeem nkaus xwb lossis nyeem / sau cov ntaub ntawv muaj nyob rau hauv lub tshuab cuab yeej processor lossis NC nco, suav nrog kev sib pauv tsis cuam tshuam txog lub tshuab cuab yeej processor, tshuab cuab yeej lub xeev tau. parameters, System ntaub ntawv xws li kev ua tsis.
Yooj yim hu hom ntawm macro program
Qhov kev hu yooj yim ntawm qhov program macro txhais tau hais tias nyob rau hauv qhov kev zov me nyuam tseem ceeb, qhov kev pab cuam macro tuaj yeem raug hu los ntawm ib qho thaiv.
Hom ntawv thov:
G65 P (tus naj npawb macro program) L (tus lej ntawm qhov rov ua dua) (ua haujlwm sib txawv).
Ntawm lawv: G65 - macro program hu ua lus txib;
P (macro program nab npawb) - tus lej ntawm qhov program macro hu ua;
L (tus naj npawb ntawm kev rov ua dua) - tus naj npawb ntawm kev rov ua haujlwm ntawm macro program, thaum tus lej rov ua dua yog 1, nws tuaj yeem raug tshem tawm;
(Variable Assignment) - Muab qhov tseem ceeb rau cov hloov pauv siv hauv macro program.
Ib yam ntawm qhov kev pabcuam macro thiab subroutine yog tias ib qho kev pabcuam macro tuaj yeem raug hu los ntawm lwm qhov kev pabcuam macro, txog li 4 zaug.
Macro program sau hom ntawv
Cov ntawv sau ntawm ib qho kev pabcuam macro yog tib yam li cov txheej txheem subroutine. Nws hom ntawv yog:
0-(0001-8999 yog tus lej macro program)
N10 command
N-M99
Nyob rau hauv cov ntsiab lus ntawm qhov kev pab cuam macro saum toj no, ntxiv rau cov lus qhia siv ntau tshaj plaws, kev hloov pauv, cov lus qhia ua lej lej thiab lwm cov lus qhia tswj kuj tuaj yeem siv. Tus nqi sib txawv yog muab rau hauv macro program hu rau kev qhia.

Tau txais raws li hom qauv ntawm parabola, qhov twg SQRT yog lub cim square hauv paus, thiab n yog tus coefficient
G01X=2×R2 plus n
Z=R1
Txoj kev ua, ntxiv rau 2 yog convex, n yog tus nqi ntawm qhov pib ntawm X axis
R1=R1-1
Tus nqi sib txawv increment yog 1mm
IF R1>-30 GOTOB AA
If the variable R1>-30, qhov kev zov me nyuam dhia rov qab mus rau qhov cim: AA
