Umsebenzi wenkqubo yokuhlela umkhondo wesixhobo sesixhobo somatshini se-nc

Inkqubo yokuhlela umkhondo wesixhobo yenziwe ngokuguqulwa kwendlela yesixhobo, ukuhlela umgca wokusika, ukuboniswa kwemizobo kwendlela yesixhobo, ukulayisha kunye nokukhupha umkhondo wesixhobo, njl.

1. Utshintsho lweJiyomethri

Umxholo wokuguqulwa kwejometri yendlela yesixhobo uquka uvavanyo, ukujikeleza kunye nomfanekiso wesibuko. Ukuguqulwa koguqulelo, kuphela umbindi wemela ovunyelweyo ukuba utshintshe, kwaye i-vector ye-axis yemela ayitshintshi. Ukuguqulwa komfanekiso wesibuko kunye nokujikeleza, ubungakanani obufanelekileyo besikhungo semela kunye nomphini wemela buyatshintsha.

2. Guqula utshintsho

I-transpose lutshintsho kwicala lokuhamba ukusuka kwicala lokuqala ukuya kwicala elitsha lokuhamba.Injongo yotshintsho lwe-transpose ingaba yindlela yokunxibelelana kokusika kuphela (intlawulo yesixhobo se-3d semi-precision iyasebenza) okanye indlela yeziko lesixhobo esijikelezayo, kwaye ixabiso lempazamo alikho ngaphezulu kwexabiso elivumelekileyo xa kusetyenzwa kwicala elitsha lesixhobo.Ekubeni utshintsho lwe-transposing lungatshintshi indlela ye-cutter axis, indlela yesixhobo se-machining esine-multi-coordinate ayinakutshintshwa. Utshintsho lwe-transposing lolona lusebenzayo kwi-tool track eyenziwe yi-equal-parameter discrete algorithm kwindlela ye-parametric machining. Kwi-tool track eyenziwe ngezinye iindlela ze-parametric line, imigca yokusika ingabethelwa ngobude obulinganayo be-arc ngokweendawo ezichaziweyo ngaphambi kotshintsho lwe-transposing, ukuze inani leendawo zesikhundla somgca ngamnye wokusika lifane kwaye lisasazwe ngokulinganayo.

3. Cima

Injongo yokusebenza kokucima ingaba yithrekhi yesixhobo kwindawo yokuma, kwicandelo lokusika, umqolo wokusika, ibhloko yokusika okanye kwanohlelo lonke, okanye inxalenye yethrekhi yesixhobo esinqumliweyo.

4. Umthungi

Into yendlela yesixhobo eza kunqunyulwa kufuneka ichazwe kuqala, emva koko into yokunqunyulwa, njengomphezulu wokuhlola, kufuneka ichazwe. Okokugqibela, chaza iindawo eziza kucinywa. Umsebenzi wokunqunyulwa ufuna i-algorithm yokudibana phakathi kwento enqunyiweyo (indlela yesixhobo) kunye nento enqunyiweyo (njengomphezulu wokuhlola).

5. Buyisela kwimeko yesiqhelo

Imo yokusebenza yokubuyisela iquka iintlobo ezimbini: enye kukubuyisela kwihlabathi liphela, oko kukuthi, ukubuyisa zonke izinto zethrekhi yesixhobo ezisusiweyo; enye kukubuyisela nge-cyclic, oko kukuthi, ngokwendlela yokucima ngokulandelelana ukubuyisela into yethrekhi yesixhobo esusiweyo, ngalo lonke ixesha umsebenzi wokubuyisela, buyisela into yethrekhi yesixhobo esusiweyo, de yonke into yethrekhi yesixhobo esusiweyo ibuyiselwe.

6. Ukudibanisa izinto zombini

Into yokusebenza ehambelanayo inokuba yindlela enye eya kwindlela, okanye ingaba yindlela yesixhobo kuyo yonke inkqubo. Umsebenzi we-homogenization uquka oku kulandelayo:

(1) umgca wokusika ngokwenqaku u-N ukuze ufumane ubude obulinganayo be-arc encryption. Le ndlela yile: okokuqala, ukufakela i-cutting line curve, uze emva koko ngokwe-arc length ye-curve discrete ukuya kuma-N points. I-vector eqhelekileyo ye-cutter axis kunye ne-swing plane iguqulwa kuqala ibe yi-trajectory ye-vector endpoint, ize ifakwe kwaye ikhutshwe, ize ekugqibeleni iguqulwe ibe yi-unit vector.

(2) kumqolo wokusika ngokwempazamo enikiweyo, indlela yokujonga iparameter iyasetyenziswa ukuze kuhlolwe indawo yesikhundla ngokuthe ngqo.

(3) faka indawo yokusika phakathi kwamanqaku amabini endawo ngokudityaniswa okuthe ngqo.

7. Cwangcisa

Xa yonke eminye imisebenzi yokuhlela igqityiwe, umkhondo wesixhobo unokudityaniswa kwaye ulungiswe. Okokuqala, ulwalathiso lwesixhobo kufuneka luchazwe (olungangqinelani nolwalathiso lwesixhobo olubekwe yinkqubo ngexesha lokubala indlela yesixhobo), ulwalathiso lwesixhobo lusenokungangqinelani nolwalathiso lwesixhobo olubekwe yinkqubo ngexesha lokubala indlela yesixhobo, kwaye ukuphakama kokuphakamisa isixhobo kufuneka kunikwe kwicala elinye lesixhobo. Nje ukuba ezi migaqo zamkelwe, inkqubo iya kulungelelanisa ngokuzenzekelayo imveliso yeendlela zesixhobo kuhlelo.
