Abstract:

Bad performance in accuracy is an important factor which makes single point incremental forming was not used widely.According to the measurement of the pyramidal parts,it was suggested that the accuracy was high near the corner and in the vertical direction.A method to describe the shape of the surface of pyramidal parts in single point incremental forming was proposed.Compared with the data gained by experiments,the accuracy of the model is acceptable.A compensatory process was also proposed to increase the part accuracy significantly.

Key words: single point incremental forming, pyramidal part, bulge of surface, compensatory process
