The traditional manufacturing equipment is hard to meet the demand of high-speed

high-precision and high-flexible machining

Research and development of high-performance processing equipment is imperative. In order to achieve the goal of high-speed and high-precision machining

a 5-axis hybrid robot for milling operation is proposed. A brief introduction of the robot and its kinematic analysis are presented. To improve the machining accuracy

the principle of parametric curve interpolation and its application in the hybrid robot are studied. Finally

taking the helical milling of holes as an example

the experiment of milling holes on titanium alloy is carried out. Simulation and experimental results show that the parametric curve interpolation method can effectively limit the feedrate fluctuation and improve the machining accuracy. In the end

it is pointed out that the hybrid robot has the characteristics of high-rigidity

high-speed

high-precision and high-flexibility

and it has broad application prospects in the aviation manufacturing industry.
