Polishing and grinding of energy storage device

What is a robotic grinding and polishing device?

This article provides a new device and variable impedance force control appraoch for the robotic grinding and polishing of aeroengine blades. Specifically, a new full feature grinding and polishing device is designed by considering the different features of blades and integrating tools corresponding to different features.

How is material removed during grinding and polishing?

Material is removed through plastic flow rather than brittle fracture during grinding and polishing. This is due to the presence of elastically compliant medium near the tool surface, which causes the interaction between abrasives and workpiece to take place close to the brittle-ductile transition point.

Why is grinding and polishing important?

Therefore, as the final stage of blade forming, grinding and polishing play an important role in contour accuracy and surface quality [, , ]. At present, manual operation mode is extensively employed in the grinding and polishing of blades. However, the efficiency is low and the quality is difficult to guarantee.

What is the difference between grinding and polishing?

It should be noted that grinding and polishing are different [54, 55], and due to the need to remove allowance for the blade basin, the blade back and the blade edge, the robotic grinding is used; since the root corner and the edge plate only require surface roughness, the robotic polishing is used. Fig. 1.

How to design a full feature grinding & polishing device?

Specifically, a new full feature grinding and polishing device is designed by considering the different features of blades and integrating tools corresponding to different features. Then, a variable impedance control algorithm is given by designing the stiffness and damping parameters to vary with force tracking errors and have boundaries.

What is compliant grinding and polishing?

Compliant grinding and polishing are categorized into 5 levels that span the closed-loop of complete machine component chain.
