Abstract
This guide proposes a method to evaluate the performance of optimized log and cant breakdown equipment as a tool for mill personnel to improve production efficiency. Optimized systems are found in all aspects of modern sawmills, and evaluating their ability to maximize product value is not necessarily a simple task.. Analytical methods presented in this guide are primarily intended for sawmill technical staff, i.e. technicians and engineers responsible for process improvement. With this guide and a better understanding of optimizers’ operating mode, they will be in position to implement a control method based on the efficiency of the log breakdown equipment To be successful, a performance evaluation test needs to be properly planned. Once objectives have been clearly defined, a methodology must be laid out for the results to be significant and conclusive. Forintek specialists are available at all times to help a company set up a project of this nature.

Abstract
To document the current state of sawing performance in Canadian sawmills, a survey was carried out in 47 mills located in the major lumber producing regions of Canada: B.C., Alberta and Quebec. The survey was restricted to sawmills producing softwood lumber products, and to band and circular saws used for primary and secondary breakdown. Data characterizing sawing performance, as well as detailed information on saw and machinery specifications, were collected during visits to each participating sawmill. The results of the survey are presented in this report. Detailed specifications are given for band and circular saws, and sawing performance levels are discussed. The results of the survey show that considerable opportunities exist for improving the performance of both band and circular saws. The large range in saw kerf widths identified in the survey indicate that lumber recovery could be significantly improved by reducing kerf to the levels of the best machines. The performance of these machines demonstrates that thin kerf widths can be achieved while high production rates and small sawing variation are maintained. Specifications for the thinnest kerf machines are presented in the report and opportunities for improving sawing performance levels are also discussed. This report will interest sawmill managers, sawfilers and other mill personnel who want to know how the sawing performance of their mill compares to that in similar mills included in the survey.
