← Back to Products › Cutting Tools — Tool Life & Cost per Part

Buy on cost per part. Not on tool price.

Tool-life monitoring that counts every part on every tool automatically — so you replace tools on time, avoid scrap, protect the spindle, and finally know what each tool really costs you. The cheapest tool is not necessarily the one with the lowest cost per part.

The problem

Tool life lives in a spreadsheet — or in the operator's head.

Cutting tools are one of the four largest cost lines in a CNC shop, and the least measured. Changes are logged by hand, if at all. Wear is judged by sound and feel. Purchasing sees a tool price; nobody sees the cost per part.

Replaced too late — or too early

Too late means scrap, rework and a damaged spindle. Too early means money in the bin. Without a count, both happen every week.

Which tool is actually cheaper?

The tool price is on the invoice. The cost per part — tool price divided by parts it really made — is nowhere.

Inventory guessed, not forecast

Shortages stop machines; excess ties up cash. Nobody has the usage history to plan from.

The cheapest tool is not necessarily the one with the lowest cost per part.

What you get

Every tool counted. Every change on time. Every cost known.

Replace tools on time, avoid scrap, keep machine health, manage inventory and repair — with the count coming from the machine, not from a form.

01 · Real-time monitor

Active tools, live, per machine

Machine, workpiece, operation, catalogue number and tool ID, actual tool life against its limit, usage % and alert threshold — for every tool currently in a spindle. Tools are monitored by their ID.

02 · Alerts & daily reports

Warned before end of life. Reported every morning.

Alerts when a tool approaches its life so the change happens at a planned stop, not mid-cut. A daily PDF with every change, early and late, and the cost per part by tool.

03 · Analytics

Compare tools and suppliers on cost per part

Wear rates by tool and application. Which alternative made more parts on the same job. Forecast consumption from real history — and negotiate with data on the table.

Data entry

Two ways in for the tool.
One way in for the count.

The tool change is recorded once. The parts are counted by the machine.

1 · Manual input

Log the change at the machine

Operator or setter records the tool change at the kiosk or tablet: machine, catalogue number, tool ID, standard life, PIN. Ten seconds.

2 · Automatic

Tool-change event from your system

A scheduled task reads a simple event file — machine, date and time, catalogue number, description, standard tool life — from your tool-management or presetter software.

Tool set · per part number

The right tools come with the part

Each part number carries its set of tools — catalogue numbers and tool IDs — from the ERP gateway or a csv/xls export of the warehouse stock. When a new part number is registered on a machine, the platform brings up that set and the setter selects the tool IDs he is mounting. From then on each tool is monitored by its ID.

Count · from the machine

Parts counted from the signals

Through the electrical signals every machine has: an IoT device the electrician installs in under an hour, the Universal Adapter in the cloud. Every cycle adds to the tool's life — no typing, no estimate.

Why cost per part

Your cutting-tools story is our story.

Twenty-five years ago I was an application engineer at one of the world's leading cutting-tool makers, breaking into a market held 100% by a local competitor selling at a third of our price. We won it with tests, not price: our tools cut cycle times by 70%, and the site's throughput tripled. The tool price became irrelevant.

Years later the competition caught up, and the real fight began: convincing purchasers to evaluate tools on cost per part, not tool cost. Every improvement cycle needed proof. That proof is what Tool Life Monitoring produces — automatically, on every tool, every day.

How it works

Count. Warn. Change. Learn.

The loop runs on every tool, on every machine, every day.

01 · Count

Parts from the machine

Each cycle the machine reports is added to the tool in the spindle. Lifespan % moves in real time.

02 · Warn

Before end of life

The alert arrives while there is still a planned stop ahead — on the floor monitor and the phone.

03 · Change

Logged in seconds

The change is recorded at the machine or arrives as an event from your tool system. The new tool starts at zero.

04 · Learn

Cost per part, by tool

Real parts made per tool, by job and by supplier. The next purchase decision has data behind it.

Same platform

Tool life runs on the same connection as your OEE.

The machine connection that counts parts for tool life also feeds OEE improvement, scheduling and the AI agent. Connect once; add applications as you go.
