Ubwoko bw'uruganda rutunganya impera

Hari ibyiciro byinshi binini by'ibikoresho byo gusya mu mpera no mu maso, nko gukata hagati ugereranyije no gukata hagati (niba urusyo rushobora gukata mu buryo butunguranye); no gushyira mu byiciro hakurikijwe umubare w'imiringi; hakurikijwe inguni ya helix; hakurikijwe ibikoresho; no mu gusiga ibikoresho. Buri cyiciro gishobora kugabanywamo byinshi hakurikijwe ikoreshwa ryihariye n'imiterere yihariye.

Inguni ikunzwe cyane yo gukata ibikoresho by'icyuma, cyane cyane iyo ukata ibikoresho by'icyuma muri rusange, ni 30°. Kurangizainganda za nyuma, ni ibisanzwe kubona uruziga rurerure cyane, rufite inguni za helix 45° cyangwa 60°.Imashini zitunganya imirimbo zigororotse(inguni ya helix 0°) ikoreshwa mu bintu byihariye, nko gusya pulasitiki cyangwa ibintu bivanze na epoxy na kirahuri. Inganda zitunganya flute end zigororotse nazo zakoreshejwe mu mateka mu gukata ibyuma mbere y'uko Carl A. Bergstrom wo muri Weldon Tool Company avumbura uruganda rutunganya flute end rukozwe mu buryo bwa helical mu 1918.

Hariho inganda zikora ibikoresho byo mu mpera zifite inguni ihindagurika ya flute helix cyangwa inguni ya pseudo-random helix, hamwe n'imiterere y'inguni idahoraho, kugira ngo bifashe kumenagura ibikoresho mo ibice bito mu gihe cyo gukata (kunoza uburyo bwo gukuramo ibyuma no kugabanya ibyago byo gufungana) no kugabanya imikorere y'ibikoresho ku bice binini. Imiterere imwe n'imwe igezweho irimo n'ibintu bito nka chamfer yo mu mfuruka na chipbreaker. Nubwo bihenze cyane, bitewe n'imiterere igoye cyane n'uburyo bwo gukora, nk'iyiinganda za nyumabishobora kumara igihe kirekire bitewe no kwangirika guke no kongera umusaruro muriimashini yihuta cyaneporogaramu (HSM).

Bigenda birushaho kuba ibisanzwe ko inganda zisanzwe zikora neza zisimbuzwa izindi zihendutse kandi zihendutse.ibikoresho byo gukata(nubwo bihenze cyane mu ntangiriro, bigabanya igihe cyo guhindura ibikoresho kandi bigatuma byoroshye gusimbuza impande zashaje cyangwa zavunitse aho gusimbuza igikoresho cyose).

Imashini zikoreshwa mu gupima zigurishwa mu buryo bwa empire na metric shank ndetse na cutting diameter. Muri Amerika, metric iraboneka byoroshye, ariko ikoreshwa gusa mu maduka amwe n'amwe y'imashini ntabwo ikoreshwa mu yandi; muri Kanada, bitewe n'uko igihugu cyegereye Amerika, ni ko bimeze. Muri Aziya no mu Burayi, metric diameter ni isanzwe.
