ABSTRACT:
A fluid jet cutting system is described having a nozzle (12) through which a fluid jet is directed for cutting a workpiece (15). The workpiece (15) is supported using pins (17) each of which is provided with an alignment device in the form of a generally tubular body (104) provided with a through hole (106). The relative positions of the nozzle and workpiece (15) can be adjusted until the fluid jet passes through the through hole (106) with minimum disturbance.
In alternative embodiments, the alignment device may be provided by a cap permanently affixed in an alignment plate, or it may be constituted by the pin (17) itself.
The alignment system provides a simple method for visually verifying the jet alignment to a reference point before controlled cutting is carried out.
