Intelligent non-autogenous metalworking systems and control logic with automated wire-to-beam alignment
11465236 · 2022-10-11 · ·

Presented are intelligent non-autogenous metalworking systems and control logic for automated wire-to-beam alignment, methods for making/using such systems, and robot-borne laser welding/brazing heads with closed-loop control for real-time wire alignment. A method for controlling operation of a non-autogenous workpiece processing system includes a system controller receiving sensor signals from a position sensor indicative of a location of filler wire discharged into a joint region by a wire feeder. Using the received sensor signals, the controller determines a displacement between the wire location and a location of a beam emitted onto the joint region by a beam emitter. If the wire displacement is greater than a threshold wire displacement value, the controller responsively determines a corrective force calculated to reduce wire displacement to below the threshold wire displacement value. The controller then commands the actuator to pivot the processing head to thereby apply the corrective force to the discharging filler wire.

An offset of the workpiece relative to the user frame is determined based on the touch-sensing of the workpiece and the offset is applied to the user frame to provide the updated user frame. The unique dynamic user frame feature enables same touch sensing program to be cloned and applied on multiple robot controllers.

LAMINATION PLANNING METHOD FOR LAMINATE MOLDED OBJECT, AND LAMINATE MOLDED OBJECT MANUFACTURING METHOD AND MANUFACTURING DEVICE

A building time for building an additively-manufactured object is calculated on the basis of the inter-pass time and the welding pass time and is compared with a preset upper limit value, and welding conditions in a depositing plan are repeatedly modified until the building time is equal to or less than the upper limit value. Alternatively, corrections are repeatedly performed until the shape difference between a building shape of built-up object shape data relating to the additively-manufactured object created on the basis of the inter-pass time and the inter-pass temperature, and a building shape of three-dimensional shape data, is smaller than a near net value.

WELDING SEQUENCE GUIDANCE USING THREE DIMENSIONAL MODELS

Systems and methods are disclosed relating to welding sequence guidance using three-dimensional (3D) models. In some examples, a welding sequence program may use 3D models, rather than two-dimensional (2D) images, to guide operators through welding sequences. Since only one 3D model must be saved for each sequence, rather than potentially hundreds of 2D images, substantial memory space may be saved. Additionally, the same 3D model may be used for several welding sequences. Further, the 3D model may be animated to help the operator understand changes in perspective between steps of the welding sequence.
