Duncan’s years of optimization and controls experience with Harvey Electronics, Hemco, CSMI, USNR, Trident, Perceptron,
and ASM enables him to identify large and small issues with the complicated electronics used in the sawmill industry. He can
quantify the existing performance level of your optimization and control systems, and then suggest and implement changes needed
to enhance the systems’ performance.
Using years of experience in development, production and widely varied applications, an operational assessment of optimizer
systems will expose subtle faults in calibration, parameters, alignment, etc. that will improve your recovery. It is not that your technical people can’t identify issues – it is often more a matter of a fresh
set of eyes focusing on a particular machine center. Understanding both machines and computers puts Sawmill MD in a strong
position to make a profitable impact on your manufacturing facility.
Sawmill MD has provided optimization and operational consulting and equipment to a variety of customers, and has solved
some serious issues.
Potlatch Bemidji, MN engaged Sawmill MD to do an optimization review and tune-up on the primary breakdown (Perceptron),
edger (Hemco), and trimmer (Perceptron) systems. This effort resulted in financially significant improvements in the operations
of the facility. Sawmill MD has been re-engaged to help implement a Mill Wide Web information system at the Bemidji facility.
Sawmill MD has performed optimization audits at Harrigan Lumber in Monroeville, AL., Griffin Lumber in Cordele GA, and
McShan Lumber, McShan, AL. These engagements were to evaluate the performance of the Hemco/CSMI trimmer / edger optimizers,
to make mechanical adjustments that markedly improved scanning in the trimmer & edger lines and to tune-up the optimization
system. The results of these projects were significant quality improvements, and the overall improvement of the optimization
systems. Sawmill MD’s engagement with these and other facilities are ongoing, and include phone support, on site support,
staff training, and system upgrades.
Sawmill MD was engaged by the mill management at TR Miller, Brewton, AL to perform a log bucking study. The scope of this
project began with the evaluation of both the mechanical and electronic portions of the log bucking system. The task assigned
is to advise mill management on the status of the log bucking line, and to make recommendations for the improvement in the
efficiency of the bucking system. Sawmill MD discovered that the optimizer was not measuring diameter accurately, and worked
with the vendor to correct these errors. Once that was accomplished Sawmill MD archived a large portion of data for analysis,
and ran multiple simulations with their data. Sawmill MD used a PowerPoint presentation to show the results of the analysis,
and their recommendations to the management of TR Miller. The results from this effort has led to additional tasks that the
customer has engaged Sawmill MD to work on concerning the log bucking system.
