A method is disclosed for holding a workpiece (P) to be machined comprising the steps of: manufacturing a locking jig (1) for locking the workpiece (P) on a support base (2) by additive production techniques, the locking jig (1) comprising wall means (3) defining a loop (4a); eliminating the irregularities present on at least one end of the wall means (3) so as to define a support surface for the workpiece (P) to be machined; making a seat (6) in said at least one end of said wall means (3) intended for housing sealing means (7); making at least one opening (8) on the support base (2) connected to at least one inner space of said loop (4a) on one side, and with a vacuum means on the other side; and applying a depression that, through the opening (8) and the aforesaid inner space, enables the workpiece (P) to stick to and remain stationary with respect to said support surface during machining of the workpiece (P).
