This paper deals with a cutting deformation produced by continuous parallel cutting lines as the basic cutting line for studying the deformation of the unicursal cutting which is applied in the cutting field. Former researches about the cutting deformation had been carried out by cutting one straight line, therefore a basic research on the deformation of plate made in the cutting field exits hardly. The expeiment was done by laser cutting. The cutting deformation was generated by inherent strain, then the distributions of inherent strain were measured by the sequential removal of layers method. It is shown by experimental data of the inherent strain distribution that main factor of cutting deformation is the plate width during cutting process. The predictive equation of cutting deformation made by continuous two parallel cutting lines was proposed using parameter of the average temperature rise.
