Data storage

All measurements are fully and automatically recorded CFR21-compliant database.

Production mode

Lathe setup. Residual toricity – Controlling Blocking quality, spindle squeezing. Fringe pattern can detect: - Tool problems. - Speed problems. - Spindle problems. - Issues related to spindle speed (too slow or too fast). - Material problems and cutting quality.

R&D mode

Radius of curvature and cylinder maps,histograms, cross-sections and radial profiles.

Histogram

Displays distribution of cylinder within the measurement window of inspected the surface.

Radial Profile

Displays the optical curvature distribution of the inspected surface.

Tool offset

Tool offset diagnosis provides the adjustment needed for correction in single iteration.
