Abstract:
1. An adaptive method for manufacturing of parts of the similar complex shape by using hot isostatic pressing (HIP) of powder materials and irreversibly deformable capsules and inserts utilized as adaptation tools, based on creation of a virtual part by mathematical computer modeling and manufacturing of a test part, comprising: Step 1: Selection of a part of the most complicated geometry among the similar complex shape parts to be made from a given powder material by hot isostatic pressing; specification of the initial geometry of the capsule, inserts, and HIP process parameters by using mathematical modeling basing on the initial database of material properties of the powder, capsules, inserts and the geometry of a selected complex shape part; creation of a virtual part; manufacturing of a test complex shape part by using geometry of the irreversibly deformed can, inserts and HIP process parameters determined by the said modeling; Step 2: Analysis of the discrepancies between the manufactured test part and the said virtual test part and adaptation of the base computer model so that the discrepancies between the manufactured test part and the said virtual test part are minimized, and Application of the adapted mathematical model of densification and shrinkage of irreversibly deformed capsules, inserts and powder during hot isostatic pressing to the calculation of the geometrical parameters of the capsule and inserts for the given complex shape part and the other parts of the similar complex shape made from a given powder material; Step 3: Manufacturing of every part of the given group of the similar complex shape parts by using hot isostatic pressing of the powder material with geometry of the irreversibly deformed cans, inserts and parameters of the HIP process specified by using the created adapted computer model.
