Title:
ULTRA PLASTIC FORMING SYSTEM AND RECORD MEDIUM HOUSED ITS FORMING ANALYSIS PROGRAM
Document Type and Number:
Japanese Patent JP3945876
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide the ultra plastic forming system capable of controlling a distortion speed of an ultra plastic material more accurately, and of obtaining an excellent ultra plastic forming.
SOLUTION: According to the ultra plastic forming system, a shape of the material after deformation is obtained based on a distortion history of the material and a die shape to form the material, and a distortion speed of each element, is obtained based on a balance between a deform analysis means 5 to determine a non-contact element and a contact element out of the elements compose the material, against the die and the material composition elements including the non-contact element and the contact element. The system has a right forming pressure calculation means 4 to obtain the forming pressure so that the biggest distortion speed conforms to the distortion speed suited to the ultra plastic deforming.
