Cov Teeb Meem piav qhia: Thaum lub siab siab - ceev cnc milling ntawm Aerospace nyias {}} huab tais cov qauv hluav taws xob (phab ntsa thickness<2mm), complex dynamic coupling vibrations occur in the workpiece-tool-machine tool system, leading to chatter, periodic surface ripples, and severe dimensional accuracy deviations.

Lus teb: Tsim cov mot - Lub cev muaj zog thiab txheeb xyuas cov khoom siv hauv lub cev hauv kev hloov kho. Ua haujlwm sib txawv Helix lub tshuab molding cutters (30℃- 45℃graticity) kom cuam tshuam lub caij nyoog ntawm cov kev sib tham. Ua raws li cov khoom noj pub tshuaj raws li ntxaiv cov lus qhia tam sim no rau tiag- lub sij hawm cnc pub kev hloov kho. Utilize harmonic dampers or dynamic vibration absorbers to provide 20-30dB vibration attenuation in critical frequency bands. Ua kom zoo lub tshuab CNC clamping siv nqus plua plav chuck + Txhua tus clamp compitation kom nce system damping piv rau saum 0.08. Kwv yees tshuab tshuab tawm los ntawm kev sim ua kom zoo thiab tsim cov nyiaj them nqi kho mob rau cov haujlwm hauv cnc. Kev siv tsis meej parameter cnc machining: pawv huv machining nrog siab ceev hom-siab ceev hom, ua tiav cov kev tswj hwm ntawm RA0.4μm hauv cnc ua.

Cov Teeb Meem piav qhia: Thaum EDM hlau txiav complexular hla {}}}} Axis Cauv, thiab RA qhov sib txuas ua haujlwm ntau tshaj 1.6μm hauv EDM xaim kev ua haujlwm.

Lus teb: Establish B-spline-based five-axis tool path optimization algorithm ensuring curvature continuity in EDM wire cutting. Adopt adaptive gap control system monitoring discharge status through voltage-current characteristic curves, dynamically adjusting servo feed speed in EDM wire cutting. Implement layered discharge strategy: establish 3D electric field simulation model predicting discharge density distribution in different regions, applying reduced power parameters (30% pulse width reduction) for concave areas in EDM wire cutting. Optimize working fluid circulation system with spiral nozzle arrays ensuring >85% txaus txaus cov kev sib txuam hauv kev nyuaj hauv EDM hlau txiav. Qhia tshuab kev kawm algorithms lub tsev tawm mus rau tus kheej {2} qauv ua kom zoo raws li keeb kwm Edm xaim txiav cov ntaub ntawv. Ua Haujlwm Composite Electrode Hlau Hlau (tungsten- molybdenum alloy) txhim kho lub zog rau 1200Mpa rau EDM xaim txiav. Los ntawm cov txheej txheem ntse parameter txuam rau EDM xaim tuaj yeem kho tau kom zoo rau ± 0.00mm nrog nto zoo ncav cuag RA0.8μm.

Cov Teeb Meem piav qhia: {-} cov duab puab molding thiab sib txawv, thiab kev nyuaj siab tawg thaum muaj kev sib txhaj tshuaj molding.

Lus teb: Tsim Avrami - zZAWA tsis-}} uc {uc uc uc uc uc uc uc ucស model្ calculា and់ frystall thiab kev loj hlob ua nyob rau hauv kev txhaj tshuaj molding. Cov Qauv Tsim Loj Gradient Zog: Txhaj Tshuaj Molding Cavity Nrog rau Cheeb Tsam Los Ntawm Lub Rooj Vag Los Ntawm Kev Txhaj Tshuaj Rau Kev Txhaj Tshuaj Molding. Optimize injection molding parameters: employ multi-stage speed control with high-speed injection (300mm/s) during filling stage reducing molecular chain relaxation time, low-pressure long-duration (12-15s) holding stage promoting stress release in injection molding. Ua kom paub tus sawv cev (Talc 0.1 - 0.}} 0.}} 0.}} 0.3%) refining spherulite loj rau 5-10μm kev txhaj tshuaj molding. Siv kev co-txhaj tshuaj molding, thov 20-50Hz tsawg-zaus ua co hauv crystallization kub muaj kev cuam tshuam nrog loj spherulite tsim. Txhim kho cov txheej txheem Windows los ntawm Polarized Lub Vaj Muaj Lub Vaj Muaj Zog Polarized thiab DSC Tsim Kho Vajtse, Tsim Crystallinity-Kev Ua Haujlwm Kev Sib Raug Zoo-Ua Haujlwm Rau Kev Txhaj Tshuaj Molding. Thaum kawg, sab hauv muaj kev ntxhov siab tuaj yeem txo los ntawm 60%, txhaj tshuaj moulding khoom warpage tswj tsis pub dhau 0.02%, thiab cuam tshuam lub zog tsim kho los ntawm 40%.
