Abstract
The high profile accuracy requirements for new type aircraft engine blades prevent RABG (robotic abrasive belt grinding) from precision machining. To solve this issue, a kind of abrasive belt grinding device with a floating compensation function was designed to reduce machining errors, and a double-vector control method was proposed to optimize the processing trajectory of robotic abrasive belt grinding. A series of grinding experiments of aluminum alloy blades were carried out. The experimental results revealed that the machining profile accuracy of the blade can be significantly improved to 0.06 mm with the optimum process parameters, and the machined surface roughness was less than 0.4 μm.
