Abstract

Computer numerical control (CNC) machines execute a process automatically unless a condition occurs that triggers one or more alarms that terminate the process. Accordingly, CNC laser cutting post-process inspection is usually non-existent or minimal. However, with CNC laser welding it is more common for a visual inspection or automated inspection to be performed to verify that the process was completed. Similar issues occur when single piece parts are required in addition to which executing an offline inspection requires additional complexity in re-working any piece part. Accordingly, embodiments of the invention provide enterprises and facilities employing CNC laser cutting/welding systems with a means to overcome these limitations. Further, providing intuitive user interfaces allows the user to perform tasks directly through a touch screen interface they are viewing the work piece/piece-parts upon.

Claims (31)

1. A method comprising:

displaying to a user a view of a captured image of a workpiece either to be subjected to a process or subjected to a process by a computer numerical control (CNC) machine, wherein the captured image of the workpiece includes freehand marked lines on the workpiece indicating a shape and location of an added piece part;

automatically replacing the freehand marked lines in the captured image with fitted lines at the location of the freehand marked lines corresponding to the added piece part on the workpiece; and

upon receiving an indication for a process to be performed, adding the location to a processing sequence to be performed and executing the processing sequence with the CNC machine or a tool forming part of the CNC machine to thereby form a plurality of piece parts associated with said process, and form said added piece part at said location through additional processing with the CNC machine or the tool forming part of the CNC machine.

2. The method according to claim 1 , wherein the tool is a plasma cutting torch.

3. The method according to claim 1 , further comprising the steps of:

presenting, to the user, an option to seek advice; and

upon determining the user has selected the option to seek advice the CNC machine performs a process comprising the steps of:

transmitting to the manufacturer of the CNC machine first data relating to the process to which the workpiece was subjected; and

receiving from the manufacturer of the CNC machine second data relating to either another process to be performed upon the workpiece to re-work at least one of the plurality of piece parts or the added piece part or adjustments to the settings of the process for subsequent use by the CNC machine when executing that process.

4. The method according to claim 1 , further comprising the steps of:

presenting, to the user, an option to seek advice; and

upon determining the user has selected the option to seek advice the CNC machine performs a process comprising the steps of:

transmitting first data to a user community associated with the CNC machine, the first data comprising one or more of data relating to materials, process parameters, and item images.

5. The method according to claim 1 , wherein said shape includes a curve and the captured image of the workpiece includes a marked indicator adjacent the curve, and the method further comprises the step of automatically recognizing the curve in the captured image based on the marked indicator.

6. The method of claim 1 , further comprising the step of disregarding an additional marking on the workpiece as an added piece part based on a color of the additional marking.

7. A method comprising:

displaying to a user a view of a captured image of a workpiece either to be subjected to a process or subjected to a process by a plasma cutting system, wherein the captured image of the workpiece includes freehand marked lines on the workpiece indicating a shape and location of an added piece part;

automatically replacing the freehand marked lines in the captured image with fitted lines at the location of the freehand marked lines corresponding to the added piece part on the workpiece; and

upon receiving an indication in relation to the workpiece prior to its being subjected to a process to be performed, adding the fitted lines to a processing sequence to be performed and executing the processing sequence with the plasma cutting system to thereby form a plurality of piece parts associated with said process, and form said added piece part at said location through additional processing with the plasma cutting system.

8. The method according to claim 7 , further comprising the steps of:

presenting, to the user, an option to seek advice; and

upon determining the user has selected the option to seek advice the plasma cutting system performs a process comprising the steps of:

transmitting to the manufacturer of the plasma cutting system first data relating to the process to which the workpiece was subjected; and

receiving from the manufacturer of the plasma cutting system second data relating to either another process to be performed upon the workpiece to re-work at least one of the plurality of piece parts or the added piece part or adjustments to the settings of the process for subsequent use by the plasma cutting system when executing that process.

9. The method according to claim 7 , further comprising the steps of:

presenting, to the user, an option to seek advice; and

upon determining the user has selected the option to seek advice the plasma cutting system performs a process comprising the steps of:

transmitting first data to a user community associated with the plasma cutting system, the first data comprising one or more of data relating to materials, process parameters, and item images.

10. The method according to claim 7 , wherein said shape includes a curve and the captured image of the workpiece includes a marked indicator adjacent the curve, and the method further comprises the step of automatically recognizing the curve in the captured image based on the marked indicator.

11. The method of claim 7 , further comprising the step of disregarding an additional marking on the workpiece as an added piece part based on a color of the additional marking.
