Optimization of microstructure and coatings of circular blades to improve sawing performance of the wood manufacturing sector

本课题研究的是对圆锯进行优化，以提高改造设备的生产率。它与SM2倡议的更广泛范围保持一致，SM2倡议监督可能影响全球森林部门的先进制造技术的研究和开发。这些技术有望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出创新的生物产品。更具体地说，这项合作研究与发展拨款提案旨在开发和优化制造圆锯的材料。目标是提高转速，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个子项目展开，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)用陶瓷和固体润滑剂涂层锯，5)减少摩擦产生的热量，6)优化刃口几何形状，以减少负载和磨损，最后7)使用多材料方法开发新型锯(例如：夹层结构等)。************

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