How Does the AutoSaw Work?

   The AutoSaw process includes the following steps:

  1. Measurement:
  2. Transmission of Measurement:
  3. Dispensing of Lumber
  4. Adjustment of Lumber Length
  5. Cutting of Lumber
  6. – Optional Printing on Lumber
  7. – Optional Sorting of cut pieces



Currently framers generally measure a needed board length with a tape measure or laser measurement device.  This measurement is either brought to the saw for the framer to perform a cut, or manually relayed to a worker who is operating a chop or miter saw.  When a measurement is relayed manually and subsequently used for a manual cut, the opportunity to make an error and cut the board incorrectly is alikelihood high.  With the AutoSaw, a framer would take a measurement with a tape measure or laser measurement device, but the measurement would be automatically transmitted to the saw for a cut.  The cut would then be cut with a high level of precision.  The board would be cut to exactly the length measured.  With current technology, an error may occur as the measurement is manually transferred from the location which it is needed, marked manually on the board, and manually cut.  Human error can easily happen at any of these three steps.

Transmission of Measurement


The AutoSaw concept will employ three different possible methods of measurement transmission.  First, a worker may take a measurement with a traditional tape measure.  The measurement is then entered into a smart device – such as a cell phone – which transfers the data to the saw at which time it cuts the board.  Secondly, an automated measurement device will be integrated with the saw.  Using this method the measurement would be taken with a device and directly sent wirelessly to the saw for a cut.  The third and final method would be the use of CAD software.  Cut lengths would be inputted into the saw from the CAD software.  Boards would then be cut as required.  Methods two and three are anticipated to be developed at a later stage of development.


Dispensing of Lumber

The selected board raises into position from one of the vertical magazines.






The push bar moves the board on the slide bed.







Standard stud lumber is held in a dispenser which is attached to the saw.  When a board is called for, the dispenser will push out the proper stud for cutting.  The AutoSaw model incorporates pod-like dispensers which can be swapped out of the saw.  For example, a 2x4x8 stud pod and a 2x6x10 stud pod could be connected to the saw at the same time.  Framers could easily pull from either pod at the touch of a finger.

Adjusting of Lumber Length

The push bar retracts to make room for the positioner.







Once a stud is dispensed from the stud dispensers, it is pushed into a place which is perfectly perpendicular to the saw blade.  The device used to push the board into place will also act as the fence for the saw.  Another device will then push the board to the proper length under the saw blade.

Cutting of the lumber

Once the board is properly positioned, the saw will automatically turn on and cut the board.  Proper safety measures are to be integrated to ensure all OSHA and other safety standards.


The positioner moves the board to be cut at the designated length.
