Cant & Gang Edger Optimizer

The cant edger optimizer scans and evaluates a flitch for an optimal cant solution that is passed to an edger machine.

The cant edger optimizer gathers 3D scan data from the scanners. The optimizer supports lineal, transverse, and snapshot scanner orientations. The optimizer uses the scan data to create a 3D model of the cant. The optimizer searches for the best solution within the scanned cant, while conforming to wane limiting and dollar-price parameters set by the customer. This means that the optimizer evaluates the characteristics of individual pieces, trading off between maximizing the volume of the board(s) which will allow more wane as compared to a higher value with lower wane.

Optimizing System Features

The optimizer offers both hardwood and softwood edger solutions, as well as curve gang solutions.

  • Number of boards, different angles, and offsets within the flitch are the key parameters we optimize in a flitch.
  • The optimizing process evaluates the board’s physical external geometry, as well as the variety of allowable wane, such as Compound Wane, Saddle Wane, and Wane equivalency.


  • All NBE optimizers have tools for saving scan data, replaying saved files and assessing optimization decisions.
  • The optimizer screen dashboard contains production statistics and current solution statistics
  • The supervisor computer enables the user to review past piece solutions.

Visually shows the user the piece that was scanned and the solution that has been computed. The table included with solutions for each scanned piece, allowing the operator to review current and recent solutions.

We save the recent scanned pieces in the history for your review to be able to evaluate your system performance.

The Optimizer software runs on a standard Desktop PC on a Standard Windows Operating System and is fully customized to each sawmill application:

    • Each system features 2 identical computers: an Optimization Computer, and a Supervisor Computer.
    • Optimizer Computer is devoted full time to dollar-driven, real-time optimization.
    • Supervisor Computer provides Windows-based simulations and solution parameter editing.
    • Supervisor Computer serves as a “built-in” spare to the Optimizer Computer.
    • The Supervisor Computer is not required for production.
  • Curved or Straight optimization logic
  • Multicluster logic (Up to 3 different saw clusters)
  • Up to 20 saws per cluster.
  • Recovery (reduced thickness) boards on sides
  • Infinitely assessment of cut offsets
  • 9 assessments of cant tapers
  • Fast algorithm (important on time limited systems)
  • Timed Optimization (time limit for lineal systems)
  • 16 thickness classifications
  • 16 width classifications
  • 20 length classifications
  • 20 grade classifications
  • 400 product classifications
  • 16 species or category classifications
  • Real-time graphic plots of each solution
  • Interactive cross-section profile plots
  • Automatic save and retrieve of last 10 cants
  • Selected or automatic save of cants to archive
  • Selected or automatic replay of cants in archive
  • History log of parameter changes, calibrations, etc.
  • Automatic or requested shift reports
