The catcher tank assembly further includes a workpiece support system detachably coupleable to an interior cavity of the catcher tank. The workpiece support system may include a plurality of workpiece support modules arrangeable in an array to support a workpiece platform of the waterjet cutting machine. The workpiece platform may be formed, for example, by a series of slats supported transversely to parallel rows of the workpiece support modules. Methods and systems which relate to or include the aforementioned catcher tank assembly are also provided.

Computer based methods, systems, and techniques for planning and generating machining paths for a tool that manufactures a three dimensional object having beveled or “compound” contours from a workpiece. A computer aided design (CAD)/computer aided manufacturing (CAM) system creates intermediate machining path surfaces that extend based on a CAD solid model representing the geometry of the object to be manufactured. The intermediate machining path surfaces extend to a shape that simulates a cutting beam (e.g., a waterjet, a laser beam, etc.) of the tool. For a flat workpiece, the machining path surfaces may extend from a top surface of the workpiece, which is a tool beam entrance surface, to a bottom surface of the workpiece, which is a tool beam exit surface. An operator is able to visualize the cuts to be made and the actual finished object geometry, without requiring the creation of multiple CAD solid models.

A fluid delivery/connector system (26) includes a high pressure tubular coil (30) connected to the upper end of a flexible hose (32) by an interface connector assembly (34) which is movable in the up-and-down directions to accommodate the movement of the lower end of the flexible hose which is connected to the nozzle assembly (22) of a fluid cutter system (20). The interface connector assembly (34) is mounted on a guideway (72) which enables the interface connector assembly to travel in an up-and-down direction to accommodate the movement of the nozzle assembly (22).

Disclosed is a line catcher-type waterjet cutting apparatus in which a workpiece is subjected to the waterjet processing in a state of being clamped by a workpiece edge clamping device and a separate driving unit for the workpiece edge clamping device is provided, and in which the workpiece is clamped by the workpiece edge clamping device during the waterjet processing, while the workpiece is easily decoupled from the workpiece edge clamping device after the waterjet processing is completed, so that the waterjet processing is carried out while reciprocally conveying the workpiece in an X-direction, thereby increasing the processing accuracy of the waterjet processing and easily automating the waterjet processing.

Provided is a method of manufacturing plate-like members whereby shape defects in the plate-like members can be prevented to increase production yield and a laminate for use in the method of manufacturing plate-like members. A method of manufacturing a plurality of plate-like members by breaking a base material 11 for plate-like members into segments includes the steps of: preparing a base material 11 for plate-like members having a first principal surface 11a and a second principal surface 11b opposed to each other; forming a breaking groove 12a, 13a in the first principal surface 11a of the base material 11 for plate-like members; bonding a support film 14 to the second principal surface 11b of the base material 11 for plate-like members; bonding an adhesive film 17 to the first principal surface 11a of the base material 11 for plate-like members to cover the first principal surface 11a of the base material 11; and breaking the base material 11 for plate-like members into segments along the breaking groove 12a, 13a by pressing, through the support film 14 and with the adhesive film 17 bonded to the base material 11 for plate-like members, a region of the base material 11 for plate-like members where the breaking groove 12a, 13a is formed.

An operational monitoring system for use with a liquid jet cutting system can include an accelerometer coupled to a cutting head of the liquid jet cutting system. The accelerometer can be configured to generate motion data associated with movement of the cutting head. The system can include a computing device operably connected to the accelerometer and having a memory and a processor. The memory can store a planned data set including expected parameters associated with movement of the cutting head along a planned cut path. In some embodiments, the computing device is configured to receive the motion data from the accelerometer and correlate the motion data to the planned data set.

A collecting and discharge device for the cutting jet of a fluid jet cutting system, comprises a cutting jet collector and a discharge for the cutting medium flow collected the cutting jet collector. The cutting jet collector has a jet outflow channel with an inlet region for introducing the cutting jet. The cutting jet is in flow connection with an outlet region via an outflow line. The jet outflow channel leads into a suction chamber disposed underneath the outlet region, said suction chamber having an enlarged cross section in the outlet region compared with the cross section of the jet outflow channel. The suction chamber additionally connects the jet outflow channel with the outflow line and with a suction channel as well as being otherwise closed. The suction channel provides suction at a suction opening forming a suction mouth in a suction region surrounding the inlet region of the jet outflow channel.
