Abstract:
1. A method of cutting a multilayer structure composed of a plurality of resin layers so as to provide a predetermined shape, comprising the steps of compressing and deforming a multilayer structure, wherein at least one of the resin layers forming the multilayer structure is in a fused state above a melting point temperature of the at least one resin layer, while extending respective layers of the multilayer structure to provide a reduced thickness portion, so that an upper layer bites into a lower layer by pushing a push cutter, by a predetermined amount, into the multilayer structure supported by a cutter receiving portion; then cooling and hardening the at least one resin layer in the fused state in the multilayer structure below the melting point thereof; and then push-cutting the compressed reduced thickness portion until the push cutter abuts against the cutter receiving portion so as to converge an intermediate layer and surface resin layers of the multilayer structure to the abutting portion of the push cutter and the cutter receiving portion.
