Kuti uwane kugaya shinda, muchina unofanirwa kuve uine matatu-axis yekubatanidza.Iyo helical interpolation ibasa reCNC muchina maturusi.Chishandiso chinodzora chishandiso kuona iyo helical trajectory.The helical interpolation inoumbwa nendege denderedzwa interpolation uye mutsara inofamba perpendicular kune ndege.
Semuenzaniso: The spiral trajectory kubva papoint A kusvika kunongedzo B (Mufananidzo 1) inobatanidzwa neXY plane circular interpolation motion uye Z linear linear motion.
Kune akawanda CNC masisitimu, basa iri rinogona kuitwa nemirairo miviri inotevera yakasiyana.
G02: Pakarepo tsono denderedzwa interpolation command
G03: Counterclockwise denderedzwa kududzira rairo
Iyo thread milling motion (Figure 2) inoratidza kuti inoumbwa nekutenderera kwechombo uye kutenderera kwemuchina wehelical interpolation.Munguva yekududzirwa kweIgrid denderedzwa,
Uchishandisa iyo geometric fomu yeprop, yakasanganiswa nekufamba kwechishandiso chekufambisa gomo munzira yeZ axis, tambo inodiwa inogadziriswa.Thread milling inogona kushandiswa
Nzira nhatu dzinotevera dzekucheka-mukati.
① Arc yekucheka nzira
② Radial yekucheka-mukati nzira
③ Tangential yekupinda nzira
① Arc yekucheka nzira
Neiyi nzira, chishandiso chinocheka mushe, chichisiya pasina mavanga ekucheka uye pasina vibration, kunyangwe kana uchigadzira zvinhu zvakaomarara.Kurongeka kweiyi nzira kwakatonyanya kuomarara kupfuura nzira yeradial yekucheka-mukati, uye zvinokurudzirwa kushandisa nzira iyi paunenge uchigadzira tambo dzakakwana.
1-2: Kukurumidza kumira
2-3: Chishandiso chinocheka tangentially padivi pearc feed, uku ichidudzira chikafu pamwe neiyo Z axis.
3-4: 360 ° izere denderedzwa yetambo yekududzira mafambiro, axial movement imwe lead
4-5: Chishandiso chinocheka tangentially pamwe nearc feed uye inoita kududzira kufamba pamwe neZ axis.
5-6: Kukurumidza kudzoka
② Radial yekucheka-mukati nzira
Iyi nzira ndiyo iri nyore, asi dzimwe nguva zvinotevera zviviri zvinoitika
Chekutanga, pachave nemadiki madiki mamaki akachekwa-mukati uye akachekwa, asi hazvizokanganisa kunaka kweshinda.
Chechipiri, paunenge uchigadzira zvinhu zvakaoma zvikuru, kana uchicheka mukati memazino anenge akazara, nekuda kwekuwedzera kwenzvimbo yekubatana pakati pechishandiso uye workpiece, chiitiko chekudengenyeka chinogona kuitika.Kuti udzivise kuzununguka kana uchicheka mumhando yemazino akazara, huwandu hwekudya hunofanira kudzikiswa kusvika pa1/3 ye spiral interpolation inopa zvakanyanya sezvinobvira.
1-2: Kukurumidza kumira
2-3: 360 ° yakazara denderedzwa yehelical interpolation motion, imwe inotungamira yeaxial kufamba.
3-4: radial kudzoka
③ Tangential yekupinda nzira
Iyi nzira iri nyore kwazvo uye ine zvakanakira nzira yekucheka arc, asi yakakodzera chete kugayo kwetambo dzekunze.
1-2: Kukurumidza kumira
2-3: 360 ° yakazara denderedzwa yetambo yekududzira mafambiro, axial kufamba nemutobvu mumwe
3-4: Kukurumidza kudzoka
