Abstract
The application discloses a self-adaptive multi-axis synchronous control method for aluminum material thin-wall part machining. The method starts from extracting workpiece residual stiffness parameters and physical wave velocity parameters from a to-be-machined path coordinate sequence; the workpiece residual stiffness parameters drive the trap wave operator to perform dynamic desensitization on a synchronous error signal to generate a desensitization deviation vector; an inter-axis interference torque is mapped into a first control vector through searching a coupling stiffness matrix; a time leading operator is determined based on the physical wave velocity parameters and the first control vector; and the execution unit control phase is adjusted. The scheme compensates for the stress wave propagation time delay and isolates the cross-axis load at the control level, thereby suppressing path oscillation and trajectory instability caused by structural stiffness degradation.
