I. Verifikasyon Debaz Presizyon
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, kalibrasyon obligatwa.
2. Systematic Error Detection: Measure standard parts of different sizes (e.g., 10mm, 50mm, 100mm). If the deviation is consistently >± 2.5μm, konpansasyon obligatwa.
3. Verifikasyon Geometrik Presizyon:
Guide rail straightness: Error per meter >2μm
Worktable flatness: Full stroke error >3μm
Three-axis perpendicularity: Angular error >5 segonn arc.
II. Evalyasyon Sistèm Sonde
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, rekalibrasyon obligatwa.
Multi-probe consistency: If the deviation of each probe measuring the same dimension is >2μm, relasyon an pwofonde bezwen kalibrasyon.
III. Tanperati ak Enspeksyon Antretyen
Estabilite Tanperati: Chanjman tanperati anbyen > ± 0.5 degre ka afekte presizyon.
Antretyen chak jou: Regilyèman netwaye epi enspekte twou pwezante yo pou mete (tankou ogmante gwosè oswa deformation); reparasyon oswa ranplasman nesesè nan ka grav.
