摘要:
An audit system and method audits operation of an optimizer system in a mill, for example auditing operation of a cant optimizer which optimizes sawing patterns. The audit system may be completely independent of the optimizer. For example, the audit system may acquire information (e.g., optically) indicative of a geometry of boards downstream from a piece of equipment such as a gangsaw. The audit system may computationally reconstruct a cant from which the boards were sawn, determine an outside dimension indicative of wane, and simulate alternative sawing patterns, determining a theoretical amount of recovery that would have resulted from each and comparing such to actual recovery from the log or cant. Alternative sawing patterns may take into account various wane rules and comparison may take into account current demand and/or prices for dimensional lumber.

At least one geometric characteristic for each of a number of pieces of lumber is determined. Each of the pieces of lumber may then be logically associated with at least one of a log or a cant from which the piece of lumber was sawn.

A light source is used to illuminate a sawn portion of a piece of wood and exposed surfaces of the saw blade on both sides of the sawn portion. The sawn portion and the exposed surfaces of the saw blade are then imaged substantially concurrently using a single image generator. At least one geometric characteristic of the sawn portion and at least one geometric characteristic of the saw blade are determined based on the imaging.

The log feed speed adjustment system includes a laser system for determining deflection of a saw at specified intervals during sawing of a log. A processing system compares the determined saw deflection against preestablished deflection values to determine whether the speed of the log feed should be increased or decreased relative to an initial log speed feed value. A control system changes the log feed speed accordingly. The log feed speed is decreased at a faster predetermined rate than it is increased.

A drill string is comprised of a tubular element and an elastomeric element. The tubular element has an interior surface and a longitudinal axis. The elastomeric element is positioned on the interior surface of the tubular element, and includes one or more ribs extending from the interior surface of the tubular element and arranged in a configuration that diverges from the longitudinal axis of the tubular element. The ribs form an opening within the tubular element having a diameter of a preselected size substantially similar to a diameter of a tool to be positioned therein.

At least one geometric characteristic for each of a number of pieces of lumber is determined. Each of the pieces of lumber may then be logically associated with at least one of a log or a cant from which the piece of lumber was sawn. The geometric characteristic may be captured by one or more scanners, for example one or more laser scanners. The geometric characteristic may, for example be a measurement of thicknesses, widths and/or wane dimensions.
