Abstract：This paper analyses the basic principle of inflection alignment of frog by pressure with basic plastoelasticity, presents the determination method of pressing volume for frog alignment in order to provide theoretical guidance for frog alignment, and finally gives an example of one frog to be calculated with the method. The theory and method not only pro?vide the theoretical guidance an calculation basis, but also provide the reference to research on alignment of other mental work-piece.
