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.).

本研究项目对圆锯片进行优化改造，提高设备的生产率。它沿着更广泛的SM2倡议，监督研究和开发先进的制造技术，有可能影响全球森林部门。预计这些技术将最大限度地利用目前收获的纤维，并能够从制造过程中产生的子产品材料中创造创新的生物产品。更具体地说，这项合作研究和开发赠款提案旨在开发和优化材料，以制造圆锯。其目标是提高旋转速度，从而提高生产率，同时最大限度地减少切口。该项目将围绕7个分项目展开，涉及：1）优化钢坯的微观结构，2）使用聚焦激光束优化热处理，3）通过激光氮化对钢坯进行局部改性，4）用陶瓷涂覆锯，和5）固体润滑剂以使由于摩擦产生的热最小化，6）优化切削刃几何形状，以最大限度地减少载荷和磨损，最后7）开发使用多材料方法的新型锯（例如：夹层结构等）。
