Molao-motheo oa ho sebetsa oa polygon
Bakeng sa ho sebetsana le li-workpieces tsa polygonal holim'a lathe, sesebelisoa se khethehileng joalokaha se bontšitsoe setšoantšong se hloka ho kenngoa.

Ha e reteleha, e kenngoa holim'a poleiti e bohareng ea li-slide ho etsa hore workpiece le sesebelisoa se pota-potile ka tsela e le 'ngoe,' me kamano ea karo-karolelano ea lebelo pakeng tsa sesebelisoa le workpiece e nang le palo e itseng ea lihlooho tsa lisebelisoa e sebelisoa ho hlokomela motsamao o lekanyelitsoeng oa sesebelisoa le workpiece, e le hore e lemohuoe ho ea ka molao oa ntshetsopele Surface theha, tlatsa tshebetso ya lisekoere, hexagon, triangolo kamehla, trapezoid, moropa, thekeng, bataletseng, daemane, poligoni e sa tloaelehang le polygonal workpiece e nang le taper.
Ka mohlala, ha u sebetsana le kgutlotharo e equilateral, karo-karolelano ea phetisetso ea sesebelisoa ho workpiece ke i = 3, kahoo trajectory ea ntlha ea sesebelisoa e amanang le axis ea workpiece ke nako le nako e pheta-phetoang e koetsoeng nakong ea ts'ebetso ea ho itšeha. karolo e bohareng e pota-potiloeng ke mokokotlo e etsa kgutlotharo e batlang e le teng.
Haeba workpiece axis e ka ntle ho sesebelisoa tip tshisinyo sedikadikwe, kgutlotharo bitsoa "outer itšeha mokhoa" e bontšitsoe Figure a; haeba workpiece axis ke ka hare ho sesebelisoa keletso tshisinyo selikalikoe, e bitsoa "ka hare ho itšeha mokhoa", 'me kgutlotharo hlaha joaloka Figure b bontša.
E ka bonoa ho tloha litšoantšong tse tharo tse hlahisitsoeng, ebang mokhoa oa ho itšeha ka ntle kapa mokhoa oa ho itšeha ka hare o sebelisoa, bokaholimo ba li-workpieces tse entsoeng ka li-triangular ha li bataletse, empa ke lifahleho tse chitja tsa arc tse batlang li bataletse. Ka hona, mokhoa oa ho fetola li-polygone tse boletsoeng ka holimo ke feela E ka sebelisoang ts'ebetsong e sa hlokeng ho bata holimo holimo.
2 Kenyelletso ea lisebelisoa tse sebelisoang haholo
Kenyelletso e kaholimo ke mohopolo oa setso, 'me lits'ebetsong tse sebetsang ho na le mefuta e fapaneng ea tlhahiso ea lisebelisoa, molao-motheo o ts'oana, empa kenyelletsong ea molao-motheo, sesebelisoa se etsa motsamao o ka sehloohong holim'a spindle, workpiece e etsa motsamao o thusang. , 'me ka ts'ebetsong e sebetsang, workpiece e tsamaisoa haholo-holo holim'a spindle.
Ha ho phethola polygon, "flying cutter disk" e sebelisoa ho seha li-polygone (mahlakoreng a mararo ho isa ho a robeli) ka lehlakoreng la sesebediswa sa axisymmetric. Karolo ea ho sebetsa (sehlahisoa se seholo) le sesebelisoa se potolohang (hlooho e sehang e fofang) li sebetsa 'moho ka mokhoa o ts'oanang ho kopanya sebaka sa ho sebetsa.
Palo ea libaka tse sehiloeng li itšetlehile ka karolelano ea phetisetso le palo ea likhahla tsa ho itšeha ka sesebelisoa sa ho itšeha. Tataiso ea ho potoloha ha workpiece le sesebelisoa e fapane.
Ho sebetsa Hexagons
Ho sebetsa Rectangle
Sehahi se nang le mahare a mabeli se sebelisetsoa ho khaola li-quadrilaterals, 'me seha se nang le li-blades tse tharo se sebelisetsoa ho khaola li-hexagon, joalo-joalo Haeba ho sebelisoa litekanyetso tse fapaneng tsa phetisetso kapa palo ea likhahla tsa sesebelisoa e fetoloa, li-depressions tse kholo kapa ho kheloha ho tsoileng matsoho. li-arcs li ka hlaha holim'a sebaka sa mosebetsi.
Ka lebaka la molao-motheo ona, moralo oa kemiso o hlahisoang ke ntlha e nepahetseng ke ellipse, empa mokoloko o kentsoeng holim'a matla a wrench ke karolo ea ellipse e nang le radius e kholoanyane ea curvature, kahoo ha e ame kopano ea ho tiisa le ho hlephisa. ho sebetsa.
