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.). ************

该研究项目有关圆形锯的优化，以提高转化设备的生产率。它沿SM2计划的广泛范围保持一致，该计划监督了有可能影响全球森林部门的先进制造技术的研发。这些技术有望最大化目前正在收集的纤维的使用情况，并能够从制造过程中生产的亚产品材料创建创新的生物产品。更具体地说，该合作研发赠款提案旨在开发和优化制造圆形锯的材料。目的是提高旋转速度，从而在最小化KERF的同时提高生产率。该项目将围绕着大约7个与：1）优化钢毛坯微观结构的优化，2）使用聚焦激光束对热处理进行优化，3）通过激光硝化的局部修改钢毛坯，4）通过使用陶瓷的锯涂层和5）最小化纤维化的锯齿，并最小化，以最小化的效果，6）最小化，6）6）的速度，6）6） 7）使用多物质方法（例如：夹层结构等）开发新型锯。 ************
