Tsis txaus cov hniav rigidity: ntev thiab nyias cov hniav muaj cov tsis zoo rigidity nyob rau hauv lub machining txheej txheem, thiab nws yog nquag mus elastic deformation thaum lub sij hawm ua tiav, uas ua rau nws nyuaj rau lav lub machining raug.
Cov nqi ua haujlwm siab: kev ua haujlwm siab plaub thiab tsib-axis txuas ntawm CNC tshuab cov cuab yeej yog kim, ntev machining voj voog, tsis tshua muaj efficiency, nce nqi tsim khoom.

High-efficiency machining txheej txheem tshawb fawb
1. Kev xaiv cov cuab yeej thiab txoj kev npaj
Cov cuab yeej xaiv: rau qhov nyuaj machining ntawm titanium alloy, SKG ceev pub milling cutter tshwj xeeb tsim rau titanium alloy yog siv rau roughing, SKG milling cutter txais me me deflection lub kaum sab xis thiab tsis tshua muaj S-type insert, txiav quab yuam yog nyob rau hauv axial kev taw qhia. , thiab sab nraud ntawm lub cuab yeej txais kev zam ntawm cov qauv hollow, uas yog tsim rau lub impeller lub nyias-walled qauv thiab cov yam ntxwv ntawm cov txheej txheem tshwj xeeb, thiab nws muaj peev xwm txhim kho lub roughing efficiency thiab txo tus nqi ntawm cov cuab yeej siv.
Txoj kev npaj: Nyob rau theem grooving ntxhib, ib txoj hauv kev saum toj-down grooving yog siv txheej txheej los ntawm cov kev taw qhia ntawm tus neeg khiav dej num kom paub txog tus nqi tuav ntawm cov hniav los ntawm kev tswj cov machining cheeb tsam ntawm txhua txheej ntawm cov neeg khiav dej num los xyuas kom meej qhov rigidity. ntawm cov hniav. Hauv cov txheej txheem tiav, taw tes milling yog siv los txiav txim siab qhov nyiaj ntawm cov hniav, xaiv qhov tsim nyog cov cuab yeej ua tiav, txo cov txiav quab yuam, thiab xyuas kom muaj kev ruaj ntseg thiab kev ua tiav.
2. Optimization ntawm milling tsis
Txoj kev sim orthogonal: siv txoj kev sim orthogonal los kawm txog cov yam ntxwv ntawm ntau lub axis milling ntawm titanium alloy, thiab tshuaj xyuas qhov cuam tshuam ntawm milling ceev, pub ib tus hniav, milling dav, milling qhov tob thiab lub cuab yeej inclination lub kaum sab xis ntawm lub milling quab yuam thiab nto roughness. Tus qauv regression twv ua ntej ntawm tsib-yam milling quab yuam thiab nto roughness ntawm TC4 titanium alloy milling los ntawm carbide pob cutter raws li emulsion raws li milling kua yog tsim thiab nws rationality yog xyuas.
Simulation thiab sim validation: Kev suav cov cuab yeej axis vector thiab kev pom ntawm toolpath tau ua tiav los ntawm kev siv MATLAB nrog MAX-PAC thiab UG kev sib koom ua ke. Qhov ua tau thiab kev ua tau zoo tshaj plaws ntawm cov cuab yeej ua tau zoo tshaj plaws tau txheeb xyuas los ntawm kev simulation thiab qhov tseeb machining xeem.
3. Ntau lub hom phiaj optimization
Roughing optimization: aiming ntawm qhov teeb meem ntawm tus nqi siab thiab tsis tshua muaj efficiency ntawm titanium alloy zuag qhia tag nrho impeller roughing, tsim ib tug multi-lub hom phiaj optimization lej qauv nrog rau qhov tsawg kawg nkaus cov cuab yeej siv thiab lub siab tshaj plaws milling efficiency raws li lub hom phiaj muaj nuj nqi, thiab daws cov multi-hom phiaj optimization. Qhov teeb meem ntawm Pareto pom kev daws teeb meem frontier nrog kev txhim kho algorithm toolbox.
Kev ua tiav tiav: rau qhov yuav tsum tau muaj qhov zoo ntawm qhov chaw zoo thiab kev ua haujlwm siab ntawm titanium alloy impeller tiav, tsim kom muaj ntau lub hom phiaj optimization lej qauv nrog qhov zoo ntawm qhov zoo thiab qhov siab tshaj plaws milling efficiency raws li lub hom phiaj muaj nuj nqi, thiab txhim kho lub machining zoo thiab efficiency los ntawm optimization. algorithm.
