Process and equipment to Laser cut very high strength metallic material

16:

• The laser cutting process as recited in claim 15 wherein the clamping operations Op2 and Op6 are performed using magnetic clamping.

17:

• The laser cutting process as recited in claim 15 wherein the clamping operation Op2 is performed only on a part of the surface of the mother blank corresponding to m last untrimmed sub-blanks to be cut in the cutting operation Op3, m being an integer between 1 and n−1.

18:

• The laser cutting process as recited in claim 15 wherein the laser trimming operation Op7 is performed on each untrimmed sub-blank by laser cutting simultaneously both untrimmed cut edges of each untrimmed sub-blank.

19:

• The laser cutting process as recited in claim 15 wherein the length of a trimmed sub-blank as measured in the longitudinal direction is at least twelve times the width of a trimmed sub-blank as measured in the transverse direction.

20:

• The laser cutting process as recited in claim 15 wherein the ultimate tensile strength of the mother blank is at least 980 MPa.

21:

• The laser cutting process as recited in claim 15 wherein a longitudinal direction of the n trimmed sub-blanks is similar to a rolling direction of a coil from which the mother blank has been cut.

22:
