Manufacturing method for a metallic part and associated metallic part

20:

• The manufacturing process as recited in claim 19 wherein the angle α is from 30° to 90°.

21:

• The manufacturing process as recited in claim 20 wherein the angle α is from 60° to 90°.

22:

• The manufacturing process as recited in claim 21 wherein the angle α comprised from 80° to 90°.

23:

• The manufacturing process as recited in claim 19 wherein the sub-blanks are assembled together in the fixed pre-assembly area by spot welding.

24:

• The manufacturing process as recited in claim 19 wherein the sub-blanks are assembled together in the fixed pre-assembly area by laser welding.

25:

• The manufacturing process as recited in claim 19 wherein the stamping operation is performed by hot stamping.

26:

• The manufacturing process as recited in claim 19 wherein the stamping operation is performed by cold stamping.

27:

• The manufacturing process as recited in claim 19 wherein the sliding area further comprises at least one post-assembly area where the first and second sub-parts are still overlapping one another after the stamping operation is performed and wherein the manufacturing process further comprises a post-assembly step after the stamping operation where the first and second sub-parts are joined together in the at least one post-assembly area.

28:

• The manufacturing process as recited in claim 27 wherein said post-assembly step is performed by spot welding.

29:

• The manufacturing process as recited in claim 27 wherein the post-assembly step is performed by laser welding.

30:

• The manufacturing process as recited in claim 19 wherein the stamping operation is followed by a conforming operation using a conforming punch comprising a conforming gap in between the areas corresponding to the first and second sub-parts, the conforming gap being smaller than the at least one gap.

31:

• The manufacturing process as recited in claim 19 wherein the metallic part comprises a further first sub-part extending along said first direction and connected to the second sub-part or a further second sub-part extending along the second direction, wherein the flexible metallic blank comprises at least a further sub-blank corresponding to the further first sub-part, the flexible blank further comprising a further overlap area where the further first sub-art overlaps the second sub-part or a further second sub-part, the further overlap area comprising at least a further fixed pre-assembly are and a further sliding area.

32:

• The manufacturing process as recited in claim 19 wherein the first and second sub-parts have top sections extending at different elevation levels and wherein the overlap area between the first and second sub-blanks further comprises an extensible area connecting the fixed pre-assembly area and the sliding area, wherein said fixed pre-assembly area has a resistance to shear strength RS, expressed in MPa, said extensible area has a resistance to plastic deformation RP, expressed in MPa, and wherein RP<RS.

33:

• A metallic part manufactured according to claim 19.

34:

• The metallic part as recited in claim 33 comprising at least one set of contiguous sub-parts having at least one set of two contiguous vertical walls wherein the curvature radius measured in the transition area between said two contiguous vertical walls is equal to or less than twenty times the smallest thickness of said two sub parts.

35:

• The metallic part as recited in claim 33, the metallic part designed to be a body part of an automotive vehicle.

36:

• An automotive vehicle comprising the metallic part as recited in claim 35.
