Application study · Cutting-tool manufacturingCutting-bit end faces: expose the edge without relying on one saturated stripe
The source blue-ring capture shows a small circular cutting-bit face with shaped darker regions and a bright central strip. It provides an appearance trial for a local end face without measuring an edge angle, wear limit or cutting performance.
Prove the local end-face signal before assigning a wear or damage threshold.

5 MP monochrome global-shutter camera proposed for a contrast trial. Confirm field, sampling, exposure and algorithm on the actual application.
Proposed component
LS-KF3528M-ML
Proposed 35 mm C-mount macro lens at its printed 0.5x / 78 mm working-distance pair. The proposed 2448 × 2048 camera with 3.45 µm pixels gives a derived 16.8912 × 14.1312 mm field. Confirm focus, contrast and coverage on the actual sample; this is not a source measurement result.
Tested component
LS-FLS74
Blue LS-FLS74 explicitly named in the source bit-face example. Printed 74 mm outside diameter, 20 mm camera opening and 18 mm height. The proposed local macro view uses the printed 0.5x / 78 mm lens point.
Proposed component
LS-BT-XZ-G-6-6045
600 mm column, 600 × 450 mm breadboard, XZ adjustment, glass tray and two lighting holders as listed. Proposed bench fixture; confirm loads, travel and camera/lens clamps.

Camera and available lens CAD are published models. Lens and light envelopes use printed dimensions. The linked station uses its published base size and column height; carriage, brackets, fittings, parts and spacing are illustrative. Confirm load, travel, fasteners and clearances before ordering. Light paths explain the arrangement and do not simulate optical performance. Representative part geometry is illustrative, not reconstructed inspection evidence. The specimen and lighting angle are representative, not dimensions or settings recovered from the source capture.

The station is an optical test bench, with its two lighting holders included in the catalog listing. The 3D column and base follow the published height and footprint. Carriages, clamps and part supports are schematic: confirm camera screw pattern, lens support, light fasteners, permissible load and actual travel before ordering.

Lighting application-lab catalog capture
Evidence you can inspect
Visible in the images
A small circular end-face region, darker shaped areas and a bright central strip are visible.
What the source reports
The source captions bit-face inspection using the blue LS-FLS74.
How to use this evidence
No tool specification, labelled defect, edge measurement, camera scale or cutting test is supplied. The 3D bit end is representative, not a recovered tool drawing.
What the camera saw
Cropped from the source test sheet; original test annotations are retained. Captures are not generated or enhanced. Drag the comparison slider or use the image buttons.
The challenge
A cutting edge can saturate while adjacent face regions remain dark.
Normal tool geometry, surface finish and fixture reflections must not be mistaken for wear or damage.
How it was solved
The source identifies the blue diffuse ring and labels the application bit-face inspection. It does not identify a tool design, coating or rejection criterion.
Use the proposed 35 mm macro lens at its printed 0.5x / 78 mm point for a local end-face view. Set exposure and illumination on independently labelled accepted and damaged samples.
Why it works
- 1
Diffuse angled illumination provides a way to compare visible face and edge regions on a small reflective tool.
- 2
The recorded brightness does not establish edge sharpness, cutting angle, wear depth or tool life.
From image contrast to a production decision
What to validate on your part
A useful sample image is the starting point. These are the checks that turn the concept into a defensible inspection.
- 01
Cover the accepted tool geometry
Include permitted flute/face form, finish and fixture orientation for the actual design.
- 02
Use verified edge damage
Test known chips or wear near the required acceptance boundary without treating all bright edges as defects.
- 03
Check sampling and exposure
Confirm the smallest required feature, saturation and false calls; retain any required tool-performance test.
Explore your inspection requirementsNo limit from motion
How many pixels cover your feature?
Compare feature coverage, camera pixel requirements and exposure using your own planning inputs. These are calculated planning values, not inspection results or an accuracy specification.
Editable planning scenario. Adjust these example inputs for your application; they are separate from the source test and 3D setup. Motion allowance and target coverage are starting points to validate, not acceptance limits. Pixel count starts from the proposed camera's catalog resolution.
Enter finite numbers in every field. Field width, feature width, target coverage, exposure and allowed motion must be greater than zero; horizontal pixel count must be a positive whole number; material speed may be zero. Use values within the supported numeric range if a calculation cannot be represented.
Object sampling mm/px
Pixels across feature px
Horizontal pixels for target px
Motion during exposure px
Exposure ceiling from motion µs
Formulas and assumptions
The field, feature, speed and exposure start with neutral example values. They are not taken from the source test or the 3D illustration. Allowed motion starts at an editable 0.5-pixel example; it is not a recommended acceptance limit. Target coverage starts at an editable 5-pixel example; it is not a recommended detection or measurement threshold. The horizontal pixel count starts from the catalog Resolution row for MV-CS050-10GM(NPOE). Use the effective width after cropping, binning or decimation if those modes are enabled.
- Object sampling (mm/px) = field width (mm) / horizontal pixels.
- Pixels across feature = feature width (mm) / object sampling (mm/px).
- Horizontal pixels for target = field width (mm) × target pixels across feature / feature width (mm), rounded up to a whole pixel.
- Motion (px) = speed (mm/s) × exposure (µs) / 1,000,000 / object sampling (mm/px).
- Exposure for allowed motion (µs) = allowed motion (px) × object sampling (mm/px) / speed (mm/s) × 1,000,000.
The exposure result is the maximum duration from this motion allowance alone. At zero speed, motion sets no exposure limit; the camera, lighting, saturation and other constraints still apply. A shorter exposure does not itself guarantee a reliable inspection.
Field width and feature width refer to the same object plane. The motion calculation assumes uniform linear motion parallel to the field-width direction and a single exposure. It does not model perspective, vibration, rolling-shutter distortion, diffraction, defocus or optical distortion. A strobe may change the effective exposure.
The target result is a horizontal sampling requirement, not a camera recommendation or a change to the selected camera. It uses the effective image width after cropping, binning or decimation and does not determine the vertical resolution or sensor size. Pixel coverage alone does not establish detectability or measurement accuracy. Validate contrast, lens performance, working distance, illumination, calibration, camera exposure limits and the inspection algorithm on representative parts. Changing field width does not change the 3D model or certify that the proposed lens can achieve that field.

About this case study: the photos and camera images come from the application laboratory of the maker of the lighting and optics we sell, imaged on the parts shown; your results depend on your part, camera and set-up. This is an application-lab study, not a LumaSpec customer deployment. Source figures are reported results; proposed components require a fresh trial. The 3D scene illustrates the arrangement and does not simulate imaging performance.
