Deformation processing support system and deformation processing support method

A deformation processing support system calculating a necessary deformation amount necessary for deformation from an intermediate shape of a work to a target shape thereof based on a difference between the intermediate shape and the target shape in deformation processing for the work, the deformation processing support system comprising:

• a target shape data acquiring part that acquires target shape data of the work having a reference line disposed on a surface thereof;
• an intermediate shape data acquiring part that acquires intermediate shape data from the work having the intermediate shape and having a reference line marked on a surface thereof, during the deformation processing;
• and
• a necessary deformation amount calculating part that overlaps the target shape data and the intermediate shape data on each other by aligning the reference lines relative to each other to calculate the necessary deformation amount for each of plural positions on the work based on a difference between the target shape data and the intermediate shape data overlapped on each other, wherein
• as the overlapping of the target shape data and the intermediate shape data on each other, the necessary deformation amount calculating part:
• sets a first starting point and a first ending point on the reference line in the intermediate shape data;
• calculates a straight-line first alignment axis that connects the first starting point and the first ending point;
• sets a second starting point corresponding to the first starting point on the reference line in the target shape data;
• calculates a point on the reference line in the target shape data, that is distant from the second starting point by a distance equal to a length of the first alignment axis, as a second ending point;
• calculates a straight-line second alignment axis that connects the second starting point and the second ending point to each other;
• overlaps the intermediate shape data and the target shape data on each other such that the first alignment axis and the second alignment axis are overlapped on each other in the state where the first starting point and the second starting point match with each other;
• and
• relatively rotates the intermediate shape data relative to the target shape data centering the first alignment axis and the second alignment axis overlapped on each other.
