Ukuze ufezekise ukugaya intambo, umatshini kufuneka ube nonxibelelwano lwe-axis emithathu. I-helical interpolation ngumsebenzi wezixhobo zomatshini we-CNC. Isixhobo silawula isixhobo ukuqonda i-helical trajectory. I-helical interpolation yenziwa yi-plane circular interpolation kunye ne-linear motion perpendicular to the plane.
Umzekelo: I-spiral trajectory ukusuka kwindawo A ukuya kwindawo B (Figure 1) idityaniswe yi-XY plane circular interpolation motion kunye ne-Z linear motion.
Kwiinkqubo ezininzi ze-CNC, lo msebenzi unokuphunyezwa ngemiyalelo emibini eyahlukeneyo elandelayo.

G03: Umyalelo wokuguqulela kwisetyhula echasene newotshi
Intshukumo yokugaya intambo (Figure 2) ibonisa ukuba yenziwe ngokujikeleza kwesixhobo kunye nentshukumo ye-helical interpolation yomatshini. Ngexesha lofakelo lwezangqa ze-Igrid,
Ukusebenzisa ifom yejometri yeprop, idibaniswe nokuhamba kwesixhobo sokuhambisa i-pitch kwindlela ye-axis ye-Z, intambo efunekayo icutshungulwa. Ukugaya imisonto kunokusebenzisa
Ezi ndlela zintathu zilandelayo zokusika.
① Indlela yokusikwa kweArc
② Indlela yokusika yeradial
③ Indlela yokungena yeTangential
① Indlela yokusika iArc
Ngale ndlela, isixhobo sinqunyulwa ngokutyibilikayo, singashiyi zimpawu zokusikwa kunye nokungcangcazela, nokuba kusetyenzwa ngezinto ezinzima. Udweliso lwenkqubo yale ndlela luntsonkothile ngakumbi kunendlela yokusika i-radial, kwaye kuyacetyiswa ukuba kusetyenziswe le ndlela xa kusenziwa imisonto echanekileyo.
I-1-2: Ukumiswa ngokukhawuleza
I-2-3: Isixhobo sisika ngokukhawuleza ecaleni kwe-arc feed, ngelixa sidibanisa isondlo ecaleni kwe-axis ye-Z.
I-3-4: 360 ° isangqa esipheleleyo sentshukumo yokufaka intambo, intshukumo ye-axial ikhokelela enye
I-4-5: Isixhobo sisika ngokungxamisekileyo ecaleni kwe-arc feed kwaye senza intshukumo ye-interpolation ecaleni kwe-axis ye-Z.
5-6: Ukubuya ngokukhawuleza
② Indlela yokusika yeradial
Le ndlela yeyona ilula, kodwa ngamanye amaxesha kwenzeka ezi meko zimbini zilandelayo
Okokuqala, kuya kubakho amanqaku amancinci amancinci kwindawo yokusika kunye nokusika, kodwa ayiyi kuchaphazela umgangatho womsonto.
Okwesibini, xa kucutshungulwa izinto ezinzima kakhulu, xa usika kumazinyo aphantse apheleleyo, ngenxa yokunyuka kwendawo yoqhagamshelwano phakathi kwesixhobo kunye ne-workpiece, i-phenomenon of vibration ingenzeka. Ukuze uthintele ukungcangcazela xa usikwa kuhlobo lwamazinyo apheleleyo, isixa sesondlo kufuneka sincitshiswe sibe yi-1/3 yonikezelo lwe-spiral interpolation kangangoko kunokwenzeka.
I-1-2: Ukumiswa ngokukhawuleza
I-2-3: 360 ° isangqa esipheleleyo sentshukumo ye-helical interpolation, isikhokelo esinye sentshukumo ye-axial
3-4: ukubuya kweradial
③ Indlela yokungena yeTangential
Le ndlela ilula kakhulu kwaye ineenzuzo zendlela yokusika i-arc, kodwa ifanelekile kuphela ukugaya imicu yangaphandle.
I-1-2: Ukumiswa ngokukhawuleza
I-2-3: I-360 ° isangqa esipheleleyo sentshukumo yokufaka intambo, intshukumo ye-axial ngesikhokelo esinye
3-4: Ukubuya ngokukhawuleza
