Umgaqo wokusebenza wepolygon processing
Ukucubungula i-polygonal workpieces kwi-lathe, isixhobo esikhethekileyo njengoko kuboniswe kumzobo kufuneka sifakwe.

Xa ujika, ifakwe kwipleyiti yesilayidi ephakathi ukwenza isixhobo sokusebenza kunye nesixhobo sijikeleze kwicala elinye, kwaye ubudlelwane besantya phakathi kwesixhobo kunye nesixhobo sokusebenza kunye nenani elithile leentloko zesixhobo sisetyenziselwa ukuqonda intshukumo yesalathiso. isixhobo kunye workpiece, ukuze iphunyezwe ngokomgaqo wophuhliso Surface ukwenza, gqibezela ukusetyenzwa isikwere, ihexagon, unxantathu rhoqo, trapezoid, igubu, esinqeni, flat, idayimane, ipoligoni engaqhelekanga kunye umsebenzi wepolygonal nge taper.
Umzekelo, xa kusetyenzwa unxantathu olinganayo, umlinganiselo wokudluliselwa kwesixhobo kwi-workpiece ngu-i = 3, ngoko ke i-trajectory yencam yesixhobo enxulumene ne-axis ye-workpiece yi-curve ephindaphindiweyo evaliweyo ngexesha lenkqubo yokusika, kwaye indawo ephakathi ejikelezwe ligophe yenza unxantathu oqikelelweyo.
Ukuba i-axis workpiece ingaphandle isixhobo incam intshukumo isangqa, unxantathu ebizwa "indlela yokusika yangaphandle" iboniswe kuMfanekiso a; ukuba i-axis workpiece ingaphakathi isixhobo incam intshukumo isangqa, ibizwa ngokuba "indlela yokusika yangaphakathi", kwaye unxantathu ibonakala ngathi Figure b ibonisa.
Inokubonwa kwimiba ye-triangular eveziweyo, ingaba indlela yokusika yangaphandle okanye indlela yokusika yangaphakathi isetyenzisiweyo, iindawo zokusebenza ze-triangular ezicutshungulwayo azikho flat, kodwa zisetyhula ze-arc ubuso obumalunga ne-flat. Ngoko ke, indlela yokuguqula iipolygons ezikhankanywe ngasentla kuphela Inokusetyenziswa ekuqhubeni okungafunekiyo ukuphakama okuphezulu.
2 Intshayelelo yezixhobo ezisetyenziswa ngokubanzi
Intshayelelo engentla yithiyori yemveli, kwaye kwizicelo ezisebenzayo kukho iindlela ezahlukeneyo zokubonisa isixhobo, umgaqo uyafana, kodwa kwintshayelelo yomgaqo, isixhobo senza intshukumo ephambili kwi-spindle, i-workpiece yenza intshukumo encedisayo. , kwaye kwizicelo ezisebenzayo, i-workpiece ishukunyiswa ikakhulu kwi-spindle.
Ekujikeni kwepolygon, i-flying cutter disk isetyenziselwa ukusika iipoligoni (amacala amathathu ukuya kwasibhozo) kwicala le-axisymmetric workpiece. Isixhobo sokusebenza (i-spindle engundoqo) kunye nesixhobo esijikelezayo (intloko ye-flying cutter) isebenza kunye ngendlela edibeneyo yokutshiza indawo yokusebenza.
Inani leendawo ezisikiweyo zixhomekeke kumlinganiselo wokudluliselwa kunye nenani leengqungquthela zokusika kwisixhobo sokusika. Isalathiso sokujikeleza kwendawo yokusebenza kunye nesixhobo sichasene.
Ukusetyenzwa kweeHexagons
Ukusetyenzwa kweRectangle
I-cutter enamacangca amabini isetyenziselwa ukusika i-quadrilaterals, kwaye i-cutter enamacangca amathathu isetyenziselwa ukusika i-hexagons, njl. Ukuba imilinganiselo yokuhambisa eyahlukileyo isetyenzisiwe okanye inani leemida zokusika isixhobo litshintshiwe, ukudakumba okukhulu okanye ukuphambuka okuphumayo. Iiarcs zinokuvela kumphezulu wesixhobo sokusebenza.
Ngenxa yalo mgaqo-siseko, i-trajectory ye-outline eyenziwa yi-tip point ifana ne-ellipse, kodwa ijika eliphunyeziweyo kumphezulu wamandla we-wrench licandelo le-ellipse kunye ne-radius enkulu ye-curvature, ngoko ayichaphazeli ukuqinisa kunye nokukhulula. ukusebenza.
