UNCOMPROMISED PRECISION: WHY METROLOGY ACCURACY MATTERS

Comparison of poor quality EDM notch machining vs high precision NDT flaw tolerance

❌ Conventional EDM (Uncontrolled Erosion)

Precision Deviation: Uncontrolled erosion causing massive dimensional error (+26.6% deviation)

Geometry Defect: Tip rounding, edge distortion, and angle mismatch under optical microscope

NDT Acoustic Impact: High acoustic noise, false echoes, and signal distortion during calibration

⚠️ UNCONTROLLED DISTORTION

CMM optical metrology inspection software verifying sub-micron EDM notch depth

✅ Kernel Test Sub-Micron CMM Mastery

Precision Deviation: Strict tolerance control (±0.006 mm/ < 0.5% target variance)

Geometry Control: Perfect equilateral geometry, sharp bottom contour, and zero tip blunting

NDT Acoustic Impact: Clean, sharp, and highly repeatable echo signals for dependable NDT results
