Cutting Tool Flank Wear RUL Tracker
Log flank wear land VB readings, see the wear trend and get a projected date when the 0.3 mm limit will be reached.
Readings stay in your browser (localStorage) โ nothing is uploaded.
Straight-line (least-squares) extrapolation of your logged readings to the 0.3 mm alarm threshold (warning at 0.2 mm). A low Rยฒ means the trend is noisy โ log more readings before trusting the projection.
Field notes from maintenance practice
Measure VB with a toolmaker's microscope or a phone macro lens against the insert edge after a fixed number of parts โ consistency of the measurement moment is what makes the trend predictive. Many shops convert the projected date into 'parts remaining' by multiplying days by parts/day, then set the tool changer counter just under it. The default action limit of 0.3 mm comes from ISO 3685 tool-life testing, which defines VB = 0.3 mm average flank wear as the standard end-of-life criterion for carbide turning; adjust it if your OEM or procedure specifies otherwise.
Linear extrapolation is honest only when the Rยฒ is decent (โฅ 0.7) and degradation is steady. Carbide flank wear typically grows steadily through its middle life then accelerates sharply at the end, so intervene before the projection, not at it. If the last reading jumps far off the line, re-measure before believing it โ measurement technique drifts too.

About Cutting Tool Flank Wear RUL Tracker
This tracker is a remaining-useful-life (RUL) estimator for flank wear land VB. Log a dated reading whenever you measure; the tool fits a least-squares straight line through your history and projects when it will cross the 0.3 mm action limit (warning at 0.2 mm) โ turning scattered measurements into a forecast date you can plan parts and downtime around.
How to use Cutting Tool Flank Wear RUL Tracker
- 1Enter each dated measurement as you take it โ readings persist in your browser between visits.
- 2Adjust the alarm (and warning) threshold to your OEM or procedure limit if it differs from the default.
- 3Read the fitted trend, Rยฒ, days-to-alarm and the projected date โ then plan parts and downtime around that date.

Frequently asked questions
What limit should trigger action for flank wear land VB?+
The widely used limit is 0.3 mm (ISO 3685 tool-life testing, which defines VB = 0.3 mm average flank wear as the standard end-of-life criterion for carbide turning). Set a warning at 0.2 mm so parts and labour are ready before the alarm. Your OEM manual or internal procedure overrides the generic figure.
Can I use spindle load instead of measuring flank wear directly?+
As a proxy, yes โ spindle power typically rises 10โ25% from sharp to worn for the same cut, and many machines expose it. But calibrate it: measure VB a few times against the load reading for your specific part and insert, then trend the load percentage here with your calibrated alarm instead of 0.3 mm.
How many readings before the projection is trustworthy?+
At least 4โ6 spread over a meaningful fraction of the asset's life, with a fit Rยฒ of about 0.7 or better. Two points always make a perfect line โ that is curve fitting, not condition monitoring. Keep measurement conditions (load, temperature, location) consistent.
Is straight-line extrapolation valid for wear?+
It is the standard first approximation for steady-state degradation, and it is deliberately conservative to act on. Many failure modes accelerate near the end (bathtub curve), so treat the projected date as the latest acceptable intervention date, not a promise.
Where is my logged data stored?+
Entirely in your browser's localStorage on this device โ nothing is uploaded to any server. Export or note critical values elsewhere if you need a permanent maintenance record shared across a team.
