Ukukhethwa kweSixhobo seGeometrical Parameters
Ukukhetha isixhobo kuluhlu olukhoyo kufuneka kuqwalaselwe iiparamitha zejometri ezifana nenani lamazinyo, i-rake angle kunye ne-blade helix angle.Kwinkqubo yokugqiba, i-chips yensimbi engenasici ayilula ukugoba.Isixhobo esinamazinyo amancinci kunye nepokotho ye-chip enkulu kufuneka ikhethwe ukwenza ukususwa kwe-chip kugudiswe kwaye kunenzuzo ekusetyenzweni kwentsimbi yentsimbi echanekileyo.Nangona kunjalo, ukuba i-angle ye-rake inkulu kakhulu, iya kwenza buthathaka amandla kwaye inxibe ukuxhathisa komphetho wokusika isixhobo.Ngokuqhelekileyo, i-end Mill kunye ne-rake angle eqhelekileyo ye-10-20 degrees kufuneka ikhethwe.I-angle ye-helix inxulumene ngokusondeleyo neyona angle ye-rake yesixhobo.Xa kusetyenzwa insimbi engenasici, ukusetyenziswa kwe-helix angle milling cutter kunokwenza amandla okusika abe mancinciinkqubo echanekileyo yomatshinikwaye umatshini uzinzile.
Umgangatho womphezulu we-workpiece uphezulu, kwaye i-engile ye-helix ngokubanzi yi-35 ° -45 °.Ngenxa yokusebenza kakubi kokusika, ubushushu obuphezulu bokusika kunye nobomi obufutshane besixhobo sezinto zensimbi ezingenasici.Ke ngoko, ukusetyenziswa kokusikwa kwensimbi engenasici kufuneka kube ngaphantsi kuneyentsimbi yekhabhoni eqhelekileyo.
Ukupholisa okwaneleyo kunye nokuthambisa kunokwandisa kakhulu ubomi besixhobo kunye nokuphucula umgangatho womphezulu wokuchanekaamalungu oomatshiniemva kokucubungula.Kwimveliso yangempela, ioli ekhethekileyo yokusika insimbi engenasici ingakhethwa njengento epholileyo, kwaye umsebenzi wokuphuma kwamanzi kwiziko loxinzelelo oluphezulu lwesixhobo sokuphotha umatshini unokukhethwa.Ioli yokusika ifafazwe kwindawo yokusika kwingcinezelo ephezulu yokupholisa ngenkani kunye ne-lubrication ukuze ifumane ukupholisa okulungileyo kunye nefuthe lokuthambisa.
