Publication number: 20200038984Abstract: A system and method to correct for deposition errors during a robotic welding additive manufacturing process. The system includes a welding power source to sample instantaneous parameter pairs of welding output current and wire feed speed in real time during a robotic welding additive manufacturing process while creating a current weld layer of a 3D workpiece part. An instantaneous ratio of welding output current and wire feed speed are determined for each instantaneous parameter pair. A short term running average ratio is determined based on the instantaneous ratios. A relative correction factor is generated based on at least the short term running average ratio and is used in real time while creating the current weld layer to compensate for deviations in a deposit level from a desired deposit level for the current weld layer.Type: ApplicationFiled: October 10, 2019Publication date: February 6, 2020Inventors: Joseph A.

Publication number: 20200038986Abstract: Computer numerical control (CNC) machines have dramatically changed manufacturing processes including plasma based cutting. Typically, plasma based cutting executes a single continuous process. However, gratings cut from a grating sheet require a number of discrete cuts be made within a grating sheet to cut each element within the grating sheet to isolate the element required from the grating. Accordingly, embodiments of the invention provide enterprises and facilities employing CNC cutting systems with a means to overcome the limitations of CNC cutting systems when cutting such elements.Type: ApplicationFiled: August 2, 2019Publication date: February 6, 2020Inventors: MIGUEL CLEMENT, STEPHANE MENARD, DOMINIQUE BRUNEAU, DAVID GABRIELS
