Lewis Controls Success Stories:
Shape Scan Mill Analysis:
The following analysis was performed by a mill that recently upgraded to a Lewis Controls
Readyscan with Shape Scan optimization. They previously were using a Lewis Controls Photo
Cell Speed Scan Optimizer on their Corley 17 degree tilted carriage.
The Shape Scan option on the Lewis Controls Readyscan Optimizer, utilizes Dynavision L4
scan heads which allows it to gather information over 120 degrees of the log surface.
This data is taken at 1 inch intervals along the length of the log. In addition to the increase
in scan information, the Shape Scan system does not require knee movement in the scanning
process. This results in quicker scan, solution, and log setting than a photo cell type system.
