Nekuenderera mberi kwekusimudzira kwehunyanzvi hwekugadzira tekinoroji uye kusimudzira, mechanized yekugadzira modhi yave kutsiva kugadzirwa kwemanyorerwo mune mamwe minda yekugadzira, kunyanya muindasitiri yekugadzira.Nekuda kwenzvimbo yakakosha yekushandiswa kwezvimwe zvikamu zvakakosha, senge tembiricha yakakwira uye kudzvanywa kwakanyanya, kuitira kuti ive nechokwadi chekugadzikana kwezvikamu, mhando yezvikamu zvinofanirwa kusangana neakakodzera zviyero, izvo zvinoisa pamberi-yepamusoro-nhanho zvinodiwa zvemachining mhando.Machining quality inonyanya kuumbwa nezvikamu zviviri: machining kunyatsoita uye machining pamusoro pemhando.Chete nekunyatso kudzora maviri akakosha malink mukugadzira, iyo mhando yekugadzira inogona kudzorwa zvakanaka uye mhando yezvigadzirwa zvemichina zvinosvika pachiyero chekushandisa.
1. Connotation yemhando yekugadzira
Machining mhando inonyanya kusanganisira maviri maficha: machining kunyatsoita uye machining epamusoro mhando, ayo anokanganisa nemhando yejometri uye zvinhu zvakateerana.
1.1 mhando yejometri mukuita machining, mhando yejometri ichakanganisa iko kurongeka kwemachining.Geometric quality inoreva kukanganisa kwejometri pakati pechigadzirwa pamusoro uye chimiro mukuita machining.Iyo inonyanya kusanganisira maviri maficha: macro geometry kukanganisa uye micro geometry kukanganisa.Kazhinji, reshiyo pakati pekureba kwemafungu uye wavelength yemacro geometry kukanganisa yakakwira kupfuura 1000. Kazhinji, reshiyo yehurefu hwemafungu kune wavelength isingasviki makumi mashanu.
1.2 mhando yezvigadzirwa mukugadzira, mhando yezvishandiso inoreva shanduko pakati pemhando yezvivakwa zvemuviri zvinosanganisirwa muchikamu chepamusoro chezvigadzirwa zvemuchina uye matrix, inozivikanwawo sekugadzirisa dhizaini.Mukugadzirisa machining, hutano hwezvinhu huchakanganisa hutano hwepamusoro, hunonyanya kuratidzwa mubasa rekuoma kwepamusoro uye shanduko ye metallographic chimiro chepamusoro.Pakati pazvo, kuomeswa kwebasa repamusoro-soro kunoreva kuwedzera kwekuoma kwesimbi yepamusoro yezvigadzirwa zvemichini nekuda kwekugadzirwa kwepurasitiki uye kutsvedza pakati pezviyo panguva yekugadzira.Kazhinji, zvinhu zvitatu zvinofanirwa kutariswa mukuongororwa kwekuomarara kwemechini zvigadzirwa, zvinoti, kuomarara kwesimbi, kuomesa kudzika uye kuomesa dhigirii.Shanduko yemetallographic chimiro chepamusoro pe layer inoreva shanduko ye metallographic chimiro chepamusoro simbi yezvigadzirwa zvemakanika nekuda kwekuita kwekucheka kupisa mukugadzira.
2. Kufurira zvinhu zvemachining quality
Mukuita machining, matambudziko emhando yekugadzira machining anonyanya kusanganisira kucheka kwepamusoro kushata uye kukuya kwepamusoro.Kazhinji, izvo zvinokanganisa kunaka kwekugadzira zvinogona kukamurwa kuita zvinhu zviviri: geometric zvinhu uye zvemuviri zvinhu.
2.1 kucheka kwepamusoro roughness mukugadzira, dambudziko remhando yekucheka kwepamusoro roughness rinonyanya kusanganisira zvinhu zviviri: geometric factor uye zvinhu zvemuviri.Pakati pavo, geometric zvinhu zvinosanganisira hombe deflection angle, sub deflection angle, yekucheka chikafu uye zvichingodaro, nepo zvinhu zvemuviri zvinosanganisira workpiece zvinhu, kucheka kumhanya, chikafu uye zvichingodaro.Mukugadzira, ductile zvinhu zvinoshandiswa pakugadzirisa workpiece, iyo simbi yepurasitiki yemidziyo inokonzeresa deformation, uye iyo yakagadzirwa nemichina ichave yakaoma.Naizvozvo, kuti uderedze hukasha hwepamusoro uye uvandudze kucheka kwekuita kana uchishandisa yepakati kabhoni simbi uye yakaderera kabhoni simbi workpiece zvinhu zvine kuoma kwakanaka, zvinowanzodikanwa kuita quenching uye kupisa kurapwa pakati pekupedza.
Paunenge uchigadzira zvinhu zvepurasitiki, kumhanya kwekucheka kuchave nekukanganisa kukuru pane yakashongedzwa pamusoro roughness.Kana kumhanya kwekucheka kunosvika kune imwe chiyero, mukana wesimbi epurasitiki deformation yakadzikira, uye kushata kwepamusoro zvakare kudiki.
Paunenge uchidzora maparamendi ekucheka, kuderedza chikafu kunogona kuderedza kushata kwepamusoro kune imwe nhanho.Nekudaro, kana chiyero chekudya chiri chidiki kwazvo, kushata kwepamusoro kuchawedzera;Chete nekudzora chiyero chekudya zvine musoro ndipo kushata kwepamusoro kunogona kuderedzwa.
2.2 kukuya roughness mukuita machining, kugaya kunokonzerwa nekukohwewa kwezviyo zvinokurisa pagumbo.Kazhinji, kana zviyo zvakawanda zvejecha zvichipfuura nepakati pechikamu chechikamu chebasa, kunyanya kukwenya pane workpiece, uye contour yezvikwangwani pa workpiece inokanganisa kuoma kwepamusoro kwekukuya.Kana iyo contour ye notch pane workpiece yakanaka, iyo roughness yekukuya ichave yakaderera.Mukuwedzera, zvinhu zvemuviri zvinokanganisa kushata kwepamusoro kwekukuya ndeyekugaya zvimiro uye zvichingodaro.Mukugadzira, kumhanya kwevhiri rekukuya kuchakanganisa kugaya kwepamusoro, ukuwo kumhanya kweworkpiece kune mhedzisiro yekugaya kwepamusoro.Iyo inokurumidza kukurumidza kwekukuya vhiri, iyo inowedzera huwandu hweabrasive particles pa unit area ye workpiece in unit time, uye idiki iyo pamusoro roughness.Kuenzaniswa nekumhanya kwekukuya vhiri, kana kukurumidza kweworkpiece kukava nekukurumidza, nhamba yezviyo zvinoputika zvichipfuura nemuchina wakagadzirwa pamusoro peiyo workpiece muyuniti nguva ichave shoma, uye hutsinye hwepamusoro huchawedzerwa.Mukuwedzera, kana iyo longitudinal feed rate yegumbo rekukuya idiki pane hupamhi hwegumbo rekukuya, pamusoro peiyo workpiece ichachekwa kakawanda, kushata kweiyo workpiece kuchawedzera, uye hutsinye hwepamusoro hweworkpiece huchaderera.
