1.Maitiro ekusarudza ekucheka kwekugaya anowanzo tarisa zvinotevera zvinhu zvekusarudza:
(1) Chikamu chimiro (tichifunga nezveprofile yekugadzira): Iyo profil yekugadzirisa inogona kazhinji kuve yakati sandara, yakadzika, mhango, shinda, nezvimwe. Zvishandiso zvinoshandiswa kune akasiyana maprofiles akasiyana. Semuenzaniso, fillet milling cutter inogona kugaya convex nzvimbo, asi kwete Milling concave nzvimbo.
(2) Material: Funga machinability ayo, chip kuumba, kuoma uye alloying zvinhu. Vagadziri vezvishandiso vanowanzo patsanura zvinhu kuita simbi, simbi isina tsvina, simbi yakakandwa, isiri-ferrous simbi, super alloys, titanium alloys uye zvakaoma zvinhu.
(3) Machining mamiriro: Machining mamiriro anosanganisira kugadzikana kweiyo workpiece sisitimu yemuchina wemuchina wekugadzirisa, iyo clamping mamiriro emudziyo inobata uye zvichingodaro.
(4) Machine tool-fixture-workpiece system kugadzikana: Izvi zvinoda kunzwisisa simba riripo rechishandiso chemuchina, spindle rudzi uye zvirevo, zera remuchina wemuchina, nezvimwewo, uye kureba kwechibatiso chibatiso uye axial/ radial runout Situation.
(5) Chikamu chekugadzirisa uye chikamu-chikamu: Izvi zvinosanganisira kugaya pamapfudzi, kugaya ndege, kugaya mbiri, nezvimwe, izvo zvinoda kusanganiswa nehunhu hwechishandiso chekusarudza chishandiso.
2. Kusarudzwa kweiyo geometric angle yekucheka milling
(1)Sarudzo yekona yekumberi. Iyo rake angle yekucheka milling inofanira kutariswa zvinoenderana nechinhu chechishandiso uye workpiece. Pane kazhinji zvinokanganisa mukugaya, saka zvinodikanwa kuve nechokwadi chekuti kucheka kumucheto kune simba rakakwirira. Kazhinji, kona yerake yeguyo idiki pane yekucheka reke angle yechibatiso; high-speed simbi yakakura kudarika cemented carbide tool; uyezve, kana kugaya mapurasitiki zvinhu, nekuda kweiyo yakakura yekucheka deformation, yakakura rake angle inofanirwa kushandiswa; pakugaya brittle zvinhu , Iyo angle angle inofanira kuva diki; kana kugadzirisa zvinhu zvine simba rakawanda uye kuoma, iyo yakaipa rake angle inogona kushandiswa zvakare.
(2)Sarudzo yekurerekera blade. Iyo helix angle β yekunze denderedzwa rekupedzisira guyo uye cylindrical milling cutter ndiyo blade inclination λ s. Izvi zvinoita kuti mazino anocheka zvishoma nezvishoma acheke mukati uye kunze kwechishandiso, achivandudza kutsetseka kwekugaya. Kuwedzera β kunogona kuwedzera iyo chaiyo rake angle, kurodza kucheka, uye kuita kuti machipisi ave nyore kuburitsa. Kune vanocheka kugaya nehupamhi hwekugaya, kuwedzera helix angle β haina kukosha, saka β=0 kana kukosha diki kunowanzoitika.
(3) Sarudzo yekona huru yekutsauka uye yechipiri deflection angle. Mhedzisiro yekona yekupinda yeface milling cutter uye simba rayo pakugayo kwakafanana neiyo yekona yekupinda yechishandiso chekutenderedza mukutendeuka. Makona ekupinda anowanzo shandiswa 45°, 60°, 75°, uye 90°. Kuomarara kwemaitiro ehurongwa hwakanaka, uye kukosha kudiki kunoshandiswa; kana zvisina kudaro, kukosha kukuru kunoshandiswa, uye kusarudzwa kwekona yekupinda kunoratidzwa muTebhu 4-3. Iyo yechipiri deflection angle inowanzoita 5°～10°. Iyo cylindrical milling cutter ine chete iyo huru yekucheka kumucheto uye haina yechipiri yekucheka mupendero, saka hapana yechipiri deflection angle, uye kona yekupinda i90 °.
