Measuring what the cutting line actually produced

Camera-based piece counting, dimension measurement and tonnage estimation for stone guillotines and cutting lines — the production number no scale ticketing system produces.

How to read this
Deployment blueprint for the guillotine and cutting line module, based on a scoped quarry engagement. Accuracy targets are agreed and calibrated during commissioning.

The situation

What we were dealing with

Quarries with guillotines and saws know what left the yard because the scale tells them. What they do not know is what the cutting line produced, how much became waste, how long each cycle took, or which operator and machine produced which output.

In practice production is logged as pieces on a clipboard, tonnage is estimated from block dimensions once in a while, or nothing is recorded at all. Cost per ton, margin per product and operator performance are therefore guesses.

No mainstream aggregate software covers this, so the gap simply persists.

Per piece
Counted, sized and weight-estimated automatically
Per shift
Waste percentage, cycle time and output per operator
Edge
Runs on-site, so poor pit connectivity is irrelevant

Approach

What we built, in order

  1. 01

    Line assessment and metric selection

    Machines, layout, lighting and existing logs are assessed, and we agree the handful of metrics that will actually change decisions: tonnage, waste, cycle time, output per operator.

  2. 02

    Camera kit and on-site compute

    Industrial cameras, mounting and enclosures are specified and installed, with an edge device doing the processing locally so the system works without reliable connectivity.

  3. 03

    Detection, measurement and estimation

    Each produced piece is detected and measured, classified by size or grade, and converted to estimated weight using material density; waste is derived from input block volume versus output.

  4. 04

    Calibration against the scale

    Estimates are compared with real weighings until they fall inside an agreed tolerance, and recalibration is repeated when materials or setups change.

  5. 05

    Reporting and maintenance signals

    Shift reports, operator productivity and cost-per-ton views are generated automatically, and cycle-time drift raises maintenance alerts before a blade or hydraulic problem stops the line.

Outcome

Where it landed

  • Production recorded automatically per machine, operator and shift with no clipboards
  • Waste percentage and cycle time visible for the first time, per material
  • Cost per ton and margin per product built on measured output rather than estimates
  • Maintenance alerts driven by measurable slowdown instead of breakdown
  • Cut output linked into inventory so finished stock reflects reality
