Izixazululo ezintathu ezilula zokuvula imishini

Ukukhishwa okusebenzayo kwe-chip kugwema ukunwaya indawo esebenza ngomshini futhi kuvimbela ama-chips ukuthi angabambeki engxenyeni kanye nethuluzi ngaphambi kokusikwa kwesibili, ngakho-ke ama-chips ensimbi kufanele aphuke kakhulu ngangokunokwenzeka ukuze ukukhiqizwa kube bushelelezi futhi kuzinze. Ngakho-ke yini okufanele ngiyenze uma ngiqhubeka nokuqopha?cnc machining ingxenye
Kunezixazululo ezintathu:
1. Khulisa ukujula kokusika kwe-Ap
2. Khulisa okuphakelayo F
3. Sebenzisa i-chip breaker blade ebukhali
Ukwandisa ukujula kokusika nokwandisa okuphakelayo kuyafana, okungukuthi, amandla okufakwa kwensimbi ayanda, ukuze kuthi lapho kusetshenziswa i-curvature efanayo, ukufakwa kwensimbi kungaphulwa.

 

Isibalo sibonisa isimo sokuthi amafayili ensimbi aphukile endaweni efanayo ngemuva kokujula kokusika. Ukwanda kokuphakelayo ukukhulisa ukujula kokusika endaweni ye-axial, ngakho-ke isizathu esifanayo, ngeke ngidwebe.
Yiqiniso, isikhathi esiningi, ukujula kokusika akukwazi ukulungiswa, ikakhulukazi ukulungisa okuphakelayo (okungcono ukunciphisa isivinini, u-F akashintshi, u-F uyakhuphuka, okungase futhi kuthuthukise impilo yamathuluzi). Nokho, ukwandisa okuphakelayo kuzoletha izinkinga ezihambisanayo.
Inkinga 1: Amandla okusika aba makhulu, isidingo samandla salo lonke uhlelo lokucubungula luyakhula, futhi ukudlidliza kungenzeka. Uma ukudlidliza kunganele, ezinye izindlela ziyadingeka.
Inkinga 2: Isiphetho sincishisiwe. Endabeni yamakhona ayindilinga afanayo, ukuqedwa kokuphakelayo okwandisiwe kuzokwehla nakanjani, ngakho-ke qaphela isiphetho se-workpiece. (Ubudlelwano phakathi kwefillet nesiphakeli bunefomula yokuhlola: Ra = (f * f ** 50) / re, okuphakelayo kukhudlwana, ikona lephuzu lethuluzi liba lincane, inani lobunzima obungaphezulu elitholiwe) Ake ngikhulume mayelana nokushintsha uhlobo lwe-groove. Uyini umkhombe? Eqinisweni, isampula ngayinye yamathuluzi inesingeniso ku-chipbreaker phambi kwayo. Ngokwesibonelo, okulandelayo.

I-chipbreaker ibheka ngokuyinhloko i-engeli yereki kanye nobubanzi beblade, njenge-engeli ephawulwe “kuphrofayela yegroove” ngenhla. Uma i-engeli inkulu, i-engeli yezinhlamvu zensimbi iba nkulu. Uma izicucu zensimbi ziba mncane, kungenzeka kakhulu. I-chip breaking, ngakho-ke uma uqhubeka nokuswayipha, kuyadingeka ukuthi ubheke i-angle yangaphambili yensingo oyisebenzisayo manje, bese ushintsha i-blade ye-engeli enkulu yangaphambili ukuze icutshungulwe, isimo sokuphuka kwe-chip sizoba ngcono.
Kukhona nobubanzi be-blade, ububanzi be-blade abukhonjiswa esithombeni esingenhla, kodwa kuboniswa ukujula kokusika, okungcono, okungukuthi, ukujula kwe-blade kulungele ukucubungula, uma usebenzisa i-blade ngokuqhubekayo, khona-ke uzobona Bheka amanye ama-blade angasika kancane kancane. Ezinye zibonisa ububanzi be-blade njengoba kuboniswe ngezansi.ingxenye yepulasitiki

Kulo mfanekiso ongenhla, ububanzi be-blade (njengo-0.21) buphawulwe. Kuqondwa kahle ukuthi ububanzi be-blade buncane, buncane bunganqunywa. Kodwa-ke, ukujula kokusika kufanele kube ububanzi be-blade, ngaphandle kwalokho akusikwa kodwa ukugaya. Ngamafuphi, ukukhuhla okuqhubekayo, khetha ububanzi be-blade encane, kungasika kube mncane, futhi isimo sokuphulwa kwe-chip singcono.
Kodwa-ke, ukukhetha i-rake angle enkulu kanye nobubanzi beblade encane nakho kuzodala izinkinga. Amandla e-blade awanele, futhi ithuluzi liyanelisa kakhulu. Ngakho-ke, uma ukhetha i-blade ebukhali bese uzama futhi, ungakhetha ethambile kancane. Kungenzeka ukwehlisa iphuzu kuqala (uma ukusebenza kahle kungadingeki).ingxenye ye-aluminium
