This research project on the optimization of circular saws to increase the productivity of transformation equipment. It is aligned along the broader spectrum of the SM2 initiative, which oversees research and development of advanced manufacturing technologies that have the potential to impact the global forest sector. These technologies are expected to maximize the usage of fibre currently being harvested and enable the creation of innovative bioproducts from the sub-product material produced during the manufacturing process. More specifically, this Cooperative Research and Development grant proposal seeks to develop and optimize materials to fabricate circular saws. The goal is to increase rotational speed and therefore productivity while minimizing kerf. This project will revolve around 7 sub-projects related to: 1) optimization of the microstructure of steel blanks, 2) optimization of heat-treatment using a focused laser beam, 3) localized modification of the steel blanks by laser-nitriding, 4) coatings of saws with ceramics and 5) solid lubricants to minimize heat generation due to friction, 6) optimization of cutting edge geometry to minimize load and wear and finally 7) development of novel saws using a multi-material approach (Ex: sandwiched structure, etc.).
