Cutting Tool Inspection

Our 3D Metrology solutions combine high precision rotation devices with 3D scanning sensor technology, allowing for capture of full 360° 3D scans of even the smallest cutting tools. Form measurements can then be extracted from these 3D cutter scans for inspection of cutting edge radius, cutting edge angles, rake angles, roughness of the cutting edge, and detection of cutter coatings. Additionally, cutting edges can be scanned before and after use allowing comparison by difference measurement for evaluation of cutter wear.

Full 360° 3D Form Measurement

High precision rotation devices combined with 3D scan sensor technology allows for capture of full 360° 3D scans. Form measurement can then be extracted from these 3D piece part scans for inspection of even the most complex geometries.

Full 360° 3D scans containing millions of data points are captured of the piece part to be inspected
A profile is “cut” across the 360° 3D scan data to select 3D points that are used for form measurements
Various form measurements are recorded, radii, height steps, angles, slot widths, etc…
Cutter specific form measurements are recorded i.e. cutting edge angles, rake angles, etc…

Full 360° 3D Scan Comparison

High precision rotation devices combined with 3D scan sensor technology allows for capture of full 360° 3D scans. These 3D piece part scans can then be compared against the ideal CAD models or other 3D scans to inspect even the most complex geometries.

Full 360° 3D scans containing millions of data points are captured of the piece part to be inspected using high precision rotation devices and overlaid on top of the CAD model
Advanced difference algorithms compare millions of data points around 360° of the inspected part for differences
Difference results are output and displayed in an easy to understand psuedo color model showing the amount of difference in various units of measure (thousandths, microns, etc…)

Cutter Wear Inspection Using 3D Scan Comparison

3D scan sensor technology allows for capture of high resolution 3D scan of cutting tools before and after they have been used. These “before and after” 3D piece part scans can then be compared against each other to easily characterize cutter wear and chipping in easy to read psuedo color output.
