Mune yakakwirira-chaiyo yekugadzirisa zviitiko zvepicosecond-level laser yekumaka michina, hwaro, sechinhu chepakati chinotsigira chikamu chemidziyo, kusarudzwa kwayo kwezvinhu kunotarisisa kugadzikana kwekurongeka kwekugadzirisa. Granite uye simbi yakakandwa zvinhu zviviri zvakajairika zvekugadzira base. Ichi chinyorwa chichaita kuenzanisa kubva kuzvinhu zvakaita sezvimiro zvemuviri, musimboti weiyo chaiyo attenuation, uye inoshanda data data, ichipa hwaro hwesainzi hwekusimudzira michina. .
I. Musiyano wePfuma Yezvinhu: Mufungo Wepazasi Wekuita Kwazvo
Granite ibwe rechisikigo rinopisa, rinoumbwa nekuvhara kwekristaro kwemaminerari akadai sequartz uye feldspar mukati. Iyo inoratidzirwa neyakaomeswa chimiro uye yakakwirira kuoma. Density yaro inowanzova pakati pe 2.7 ne 3.1g/cm³, uye coefficient yayo yekuwedzera kwekushisa yakaderera zvakanyanya, inenge (4-8) × 10⁻⁶/℃, iyo inogona kurwisa zvinobudirira pesvedzero yekuchinja kwekushisa pakururama kwemidziyo. Uye zvakare, iyo yakasarudzika microstructure yegranite inoiisa yakanakisa damping kuita, ichiigonesa kukurumidza kutora ekunze vibration simba uye kuderedza kupindira kwe vibration pakugadzirisa iko kurongeka. .
Cast iron, sechinyakare maindasitiri zvinhu, ine density inosvika 7.86g/cm³, ine simba repamusoro rekumanikidza, asi inopisa.
Nhamba yekuwedzera (inenge 12 × 10⁻⁶/℃) ndeye 1.5-3 nguva yegranite. Uyezve, kune flake graphite zvimiro mukati mesimbi yakakandwa. Munguva yekushandiswa kwenguva refu, zvimiro izvi zvinogona kutungamirira kune kushushikana mupfungwa, kukanganisa kugadzikana kwezvinhu uye zvozokonzera kuderera kwechokwadi. .
Ii. Precision Attenuation Mechanism muPicosecond-level Machining
Picosecond-level laser processing ine zvakanyanyisa zvinodiwa zvekugadzikana kwezvakatipoteredza. Chero kushomeka kushoma kweiyo base zvinhu kuchakwidziridzwa kuita mugumisiro wekugadzirisa. Kuchinja kwematembiricha, kuzunguzika kunokonzerwa nekushanda kwemidziyo, kuneta pasi pemutoro wenguva refu, nezvimwewo, zvese zvinhu zvakakosha zvinotungamira mukumisikidzwa kwechokwadi. .
Kana kutonhora kuchichinja, saizi yegranite inoshanduka zvishoma nekuda kweiyo yakaderera coefficient yekuwedzera kwekupisa. Iyo yakakura yekupisa yekuwedzera coefficient yesimbi yakakandwa ichaita kuti base iite deformation iyo inonetsa kuona neziso rakashama. Iyi deformation inokanganisa zvakananga kugadzikana kweiyo laser optical nzira uye kuita kuti iyo yekumaka chinzvimbo ichinje. Panyaya yekudedera, iyo yakakwira yekunyorovesa hunhu hwegranite inogona kudzikisira 100Hz vibration mukati memasekonzi 0.12, nepo simbi yakakandwa inoda masekonzi 0.9. Pasi pepamusoro-frequency vibration mamiriro, iko kurongeka kwemidziyo ine mabhesi esimbi yakakandwa kunowanzo chinja. .
Iii. Kuenzanisa kwe Precision Attenuation Data
Zvinoenderana nemiedzo yemasangano ehunyanzvi, panguva yekuenderera mberi kwe8-awa picosecond laser yekumaka mashandiro, kudzikisira kweiyo XY-axis yekumisikidza kurongeka kwemidziyo ine base yegranite iri mukati me ± 0.5μm. Iko kunyatso kuderedzwa kwesimbi yakakandwa base midziyo inosvika ± 3μm, ine mutsauko wakakura. Munzvimbo yakateedzerwa ine tembiricha shanduko ye5 ℃, thermal deformation kukanganisa kwegranite base midziyo ingori + 0.8μm, nepo iyo yesimbi yakakandwa base midziyo yakakwira kusvika + 12μm. .
Uyezve, kubva pakuona kwekushandiswa kwenguva refu, kukanganisa kwehuwandu hwemabhesi egranite inongova 0.03%, nepo chiyero chekusatongerwa kwemabhesi esimbi yakakandwa yakakwira se0.5% nekuda kwekugadzikana kwemaitiro. Aya data anoratidza zvizere kuti pasi peiyo yepamusoro-chaiyo zvinodiwa zvepicosecond-level process, iyo kugadzikana mukana weiyo granite base yakakosha. .
Iv. Simudzira Mazano uye Anoshanda Zvishandiso
Kune mabhizinesi anoteedzera kwekupedzisira kugadzirisa kurongeka, kukwidziridza iyo cast iron base kune iyo granite base inzira inoshanda yekusimudzira mashandiro emidziyo. Munguva yekusimudzira maitiro, kutarisisa kunofanirwa kubhadharwa kune iko kurongeka kweiyo granite base kuti ive nechokwadi chekuti iyo yepamusoro flatness inosangana nezvinodiwa zvekugadzira. Panguva imwecheteyo, mukubatana nemidziyo yekubatsira senge air flotation vibration isolation system, iyo anti-vibration kuita kwemidziyo inogona kuwedzeredzwa. .
Parizvino, mumaindasitiri akadai semiconductor chip kugadzira uye chaiyo optical component processing, laser yekumaka michina ine mabhesi egranite yakagamuchirwa zvakanyanya, zvinobudirira kusimudzira goho rechigadzirwa uye kugona kugadzira. Semuyenzaniso, mushure mekunge mumwe mugadziri wemagetsi akwidziridza simbi yekukandira base, chiyero chemhando yechigadzirwa chakawedzera kubva pa82% kusvika 97%, uye kugona kwekugadzira kwakawedzera zvakanyanya. .
Mukupedzisa, mukukwidziridzwa kwepicosecond-level laser yekumaka michina, granite, nekudzikama kwayo kwekushisa, kuita kwekunyorova kwepamusoro uye kugona kwenguva refu kwekuchengetedza, yave sarudzo yakanaka kupfuura simbi yekukanda. Mabhizinesi anogona kusarudza zvine musoro zvigadziro zvichibva pane zvawo zvekugadzirisa zvinodiwa uye mabhajeti kuti awane kukwidziridzwa kwakazara kwekuita kwemidziyo.
