I. Verifika tal-Eżattezza Bażika
1. Repeatability Test: Measure 20 times consecutively using a standard part. The repeatability accuracy should be ≤0.8μm (≤0.3μm for high-precision models). If the standard deviation is >1.2μm, kalibrazzjoni hija meħtieġa.
2. Systematic Error Detection: Measure standard parts of different sizes (e.g., 10mm, 50mm, 100mm). If the deviation is consistently >± 2.5μm, huwa meħtieġ kumpens.
3. Verifika tal-Eżattezza Ġeometrika:
Guide rail straightness: Error per meter >2μm
Worktable flatness: Full stroke error >3μm
Three-axis perpendicularity: Angular error >5 sekondi tal-ark.
II. Evalwazzjoni tas-Sistema ta' Sonda
Calibration ball diameter consistency: If the measurement difference in different directions by the same probe is >0.8μm or the roundness error is >0.5μm, hija meħtieġa kalibrazzjoni mill-ġdid.
Multi-probe consistency: If the deviation of each probe measuring the same dimension is >2μm, ir-relazzjoni tas-sonda teħtieġ kalibrazzjoni.
III. Spezzjoni tat-Temperatura u Manutenzjoni
Stabbiltà tat-Temperatura: Bidliet fit-temperatura ambjentali > ± 0.5 grad jistgħu jaffettwaw l-eżattezza.
Manutenzjoni ta 'Kuljum: Naddaf u spezzjona regolarment it-toqob tal-ippożizzjonar għal xedd (bħal żieda fid-daqs jew deformazzjoni); tiswija jew sostituzzjoni hija meħtieġa f'każijiet severi.
