Imiyalo yokuhlela yesikhungo semishini ye-CNC, uma ungayazi, woza uzoyifunda

1. misa isikhashana umyalo

I-G04X (U)_/P_ ibhekisela esikhathini sokumisa ithuluzi (isiphakeli siyama, i-spindle ayimi), futhi inani ngemva kwekheli P noma X isikhathi sokumisa okwesikhashana. Inani ngemva

Isibonelo, i-G04X2.0; noma i-G04X2000; ima imizuzwana emi-2

I-G04P2000;

Kodwa-ke, kwezinye iziqondiso zokucubungula uhlelo lwembobo (njenge-G82, G88 ne-G89), ukuze kuqinisekiswe ukunemba kwemgodi ongaphansi, kunesikhathi sokumisa isikhashana lapho ithuluzi licubungula ukuya phansi kwembobo. Ngalesi sikhathi, ingavezwa kuphela ngekheli elithi P. Uma Ikheli X libonisa ukuthi isistimu yokulawula ibheka u-X njengenani lokuxhumanisa i-eksisi engu-X futhi ikwenze.

Isibonelo, i-G82X100.0Y100.0Z-20.0R5.0F200P2000; bhola (100.0, 100.0) phansi kwembobo bese ume imizuzwana emi-2

G82X100.0Y100.0Z-20.0R5.0F200X2.0; ukubhoboza (2.0, 100.0) ukuya phansi kwembobo ngaphandle kokumisa isikhashana.

2. Umehluko nokuxhumana phakathi kwe-M00, M01, M02 kanye ne-M30

I-M00 iyisiyalezo sokumisa isikhashana esingenamibandela sohlelo. Lapho uhlelo lwenziwa, i-feed iyama futhi i-spindle iyama. Ukuze uqale kabusha uhlelo, kufanele uqale ubuyele kusimo se-JOG, cindezela u-CW (spindle phambili) ukuze uqale i-spindle, bese ubuyela kusimo se-AUTO, cindezela inkinobho ethi QALA ukuze uqale uhlelo.

I-M01 iwuhlelo olukhethayo lokumisa isikhashana. Ngaphambi kokuthi uhlelo lusetshenziswe, ukhiye we-OPSTOP kuphaneli yokulawula kufanele uvule. Umphumela ngemva kokubulawa uyafana no-M00. Uhlelo kumele luqalwe kabusha njengoba ngenhla.

I-M00 ne-M01 zivame ukusetshenziselwa ukuhlola noma ukususwa kwe-chip yobukhulu bengcezu yokusebenza ngesikhathi sokucubungula.

I-M02 iyisimiso esiyinhloko sokuphela kohlelo. Uma lo myalo wenziwe, i-feed iyama, i-spindle iyama, futhi okokupholisa kuyavalwa. Kodwa ikhesa yohlelo iyama ekupheleni kohlelo.

I-M30 iwumyalo oyinhloko wokuphela kohlelo. Umsebenzi uyafana no-M02, umehluko ukuthi ikhesa ibuyela endaweni yekhanda lohlelo, kungakhathaliseki ukuthi zikhona yini ezinye izingxenye zohlelo ngemva kwe-M30.

3. Amakheli D kanye no-H anencazelo efanayo

Izinhlaka zesinxephezelo zamathuluzi D no-H zinomsebenzi ofanayo futhi zingashintshwa ngokuthanda kwakho. Zombili zimelela igama lekheli lerejista yesinxephezelo ohlelweni lwe-CNC, kodwa inani elithile lesinxephezelo linqunywa ikheli lenombolo yesinxephezelo elingemuva kwazo. Kodwa-ke, ezikhungweni zemishini, ukuze kuvinjelwe amaphutha, ngokuvamile kubekwa ngokungemthetho ukuthi H ikheli lesinxephezelo sobude bethuluzi, inombolo yesinxephezelo isuka ku-1 iye ku-20, D ikheli lesinxephezelo serediyasi yethuluzi, futhi inombolo yesinxephezelo iqala kuNo. 21 (iphephabhuku elinamathuluzi angama-20).
