The invention discloses a mechanical part pre-deformation clamping process method based on
simulation analysis, and relates to the technical field of mechanical manufacturing. The method comprises the following steps that S1, a design drawing, material characteristic parameters, blank size specifications and technical parameters of a clamp
system of a to-be-machined part are collected; according to the method, an integrated
simulation model of a part, blank and clamp
system is constructed, blank key parameters and the
constraint relation of all parts are fused, multi-field
coupling simulation is combined, the theoretical deformation field pre-judgment precision is greatly improved, reliable data support is provided for pre-deformation design, a target compensation curved surface is generated through a geometric inversion
algorithm, and the pre-deformation design precision is improved. By matching with a pre-deformation clamp with an adjusting mechanism, reverse pre-deformation is realized, differences of different batches of blanks are adapted,
machining and rebound deformation are effectively counteracted, simulation and process parameters are corrected through a detection result by means of a closed-
loop optimization mechanism,
machining precision stability is guaranteed, trial
cutting cost and
rejection rate are reduced, and the method is suitable for
machining of various easily-deformed parts.
