Abstract

In recent years, size and capacity of wind turbines have increased significantly to meet the ambitious worldwide renewable energy targets. Extraordinarily high costs of manufacture and maintenance are one of the main issues to confine the expansion of the share of wind turbines in various renewables. To mitigate the high costs, advanced, and cost-effective repairing of wind turbine blades is critically needed to enable on-site repairing and restoration of damaged wind turbine blades. Moreover, advanced manufacturing technologies of hardened bearing steels are required to improve the functional performance of bearing and gearbox metal components. In this chapter, both conventional techniques and state-of-the-art repairing techniques for wind turbine blades (composites) are introduced firstly. Then, current machining process of hardened steels for bearing and gearbox components is summarized. Current achievements in novel machining process of hardened steel components are discussed for laser-assisted machining and cryogenic machining. The relationship between the desired surface integrity and manufacturing process conditions is explained through experimental results in literature. An overview is provided on the future applications of these advanced repairing technologies for wind turbine blades and advanced manufacturing technologies for wind turbine bearing and gearbox components.
