APPARATUS, SYSTEM AND METHODS FOR CNC MATERIAL CUTTING

Abstract

An apparatus, system, method or process for converting an original or source image into a computer image file that uses guide curves to provide for a cutting of that image onto the surface of a material. The present disclosure relates to a process of converting an image into a computer image file, such as by pixelating or rasterizing the image. The process then controls the CNC knife to cut the surface of the material at different locations, different angles, different depths, and different range of motion, based on the processing of the computer image file, thereby creating the original image, or a very close replica, on the surface of the material. By deviating the cut lines from each other, the intensity of the image can be varied.

DETAILED DESCRIPTION

[0038] As stated herein, the objective of the present disclosure is to provide an apparatus, system and methods for cutting material using a Computer Numeric Control (CNC) process to create images in the surface of the material by removing varying size sections or slices of material from the surface. In particular, the objective of the present disclosure also relates to an apparatus, system and methods in which a knife or cutting tool controlled by a CNC machine is used to cut away or remove slices of felt or PET material, using guide curves, different cutting angles, depths and range of motion, to generate different intensities, from the surface of the sheet of material, thereby leaving an image in the remaining surface area.

[0039] Referring to the drawings, wherein like reference numerals refer to the same or similar features in the various views, FIGS. 1 through 6 show different views of the improved CNC cutting system 10.

[0040] FIG. 1 shows a functional block diagram of the system 10, including the original or source image 12, the scanning device 14 for scanning the original or source image into the system 10. Of course, as understood by one having ordinary skill in the art, other ways exist of inputting or entering an original image into a computer 16, or a database 18 coupled to or connected to the computer 16. Once the original image 12 is scanned, captured, or otherwise inputted, a computer program 20 can convert the original or source image 12 through pixilation, rasterization or other methods, to create a computer image file 22 associated with the original image 12. As described in detail herein, the computer image file 22 incorporates or is made up of guide curves which will be used to control the cutting of the material.

[0041] Once the computer image file 22 is generated, a controller 24 uses the information to control a CNC cutting machine 26, as understood by one having ordinary skill in the art, to cut, slice or indent the surface 28 of the material 30, to replicate the original image 12 onto the surface 28 of the material 30.

[0042] FIG. 2 shows the CNC cutting machine 26 that includes a cutting or slicing element 32 used to cut the surface 28 of the material 30. As understood, the CNC cutting machine 26, and in particular, the cutting element 32 can be moved in three dimensions X, Y and Z to effect cuts or slices in the material 30 in three dimensional space. A number of different cutting elements or devices 32 can be used to accomplish the same cutting or slicing effect, including lasers, milling machines and/or drilling devices.

[0043] FIG. 3 shows a system flowchart for the cutting system 10. The program starts at step 40 and proceeds to initiate and utilize a scanning device 14 to scan in the original image 12 at step 42. If the original or source image 12 is a virtual or digital image, there is no need to scan the source image 12 and the process can begin at step 44.

[0044] Once scanned and/or saved into the database 18, step 44 uses the computer program 20 (stored in the database 18) to access the scanned original image 12 (also stored in the database 18) and converts the original image 12 to a computer image file 22. As described herein, the conversion includes any of a number of processes, but takes into account the intensities and/or colors of the original image 12 to generate the computer image file 22. This is important since depending on the intensities of the scanned original image 12, different ranges of motion, angles and depths (collectively guide curves) from the computer image file 22 will be used to control the CNC cutting machine 26 to remove slices from the surface 28 of the material 30 to replicate the original image 12.

[0045] Once converted, the computer image file 22 is stored in the database 20 at step 46, where, at step 48 it can be accessed by the computer program 18 for further processing. Next, at step 50, the system 10 and the computer program 18 will utilize CAD, CAM and/or CNC software to further process the computer image file 22 in order for final material cutting.

[0046] Once the computer image file 22 is ready at step 52, the program 18 accesses the controller 24 and instructs the controller 24 to control the CNC cutting machine 26. At step 54, the controller 24 controls the CNC cutting machine 26 to cut, slice or indent the surface 28 of the material 30, based on the guide curves in the computer image file, thereby creating the replicated image on the surface 28 of the material 30. The system process ends at step 56.

[0047] Although the process is described with various steps in a particular order, one having ordinary skill in the art would understand that these steps can be combined and/or further expanded without diverging from the scope of the disclosure described herein. Additionally, the order of the steps can be changed or modified, and additionally or alternatively, multiple databases or computer programs can be implemented with the same result.

[0048] The program(s) and database(s) can be located and accessed locally and/or remotely with the same results. For example, the program for converting the original image 12 to the computer image file 22 (step 44) can be located remotely, while the program or portion of the program for controlling the CNC machine (step 52) can be located locally on a local computer (or vice-versa). Another example includes a scanning device located remotely from the CNC cutting machine such that the original image 12 can be scanned remotely and the actual cutting (Step 54) can be done locally (or vice-versa). Of course, many other options exist all falling under the rubric of the disclosure herein.

[0049] FIG. 4 shows a side view of three 45 degree bevel cuts, the first 45 degree bevel cut 60, the second 45 degree bevel cut 62, and the third 45 degree bevel cut 64. The first 45 degree bevel cut 60 shows a control line 66 and a variable line 68. The control line 66 stays constant from a first end 70 (FIG. 5) of the surface 28 of the material 30 to a second end 72 (FIG. 5) of the surface 28 of the material 30. The variable line 68 deviates from the control line 66 based on the guide curve generated in the computer image file 22. The range of motion 74 is a function of the distance or deviation that the variable line 68 will move from and to the control line 66.

[0050] More or less of the shaded area 76 will be cut away depending on the deviation of the variable line 68 from the control line 66. The second 45 degree bevel cut 62 shows a smaller deviation between the control line 66 and the variable line 68 resulting in a smaller slice 78 (FIG. 5) and a minimum removal. The third 45 degree bevel cut 64 shows a larger deviation between the control line 66 and the variable line 68 resulting in a larger slice 78 (FIG. 5) and a maximum removal.

[0051] FIG. 5 shows a perspective view of a single continuous 45 degree bevel cut 80, using the control line 66 and the variable line 68. The control line 66 stays constant from the first end 70 of the surface 28 of the material 30 to a second end 72 of the surface 28 of the material 30. The changing deviation of the variable line 68 from further 82 to closer 84 to the control line 66, changes the amount of the slice 78 to be removed.

[0052] FIG. 6 shows a top view of a multiple continuous 45 degree bevel cuts 80, using the control line 66 and the variable line 68. The control line 66 stays constant from the first end 70 of the surface 28 of the material 30 to a second end 72 of the surface 28 of the material 30. The changing deviation of the variable line 68 from further 82 to closer 84 to the control line 66, changes the amount of the slice 78 to be removed (FIG. 7A).

[0053] FIGS. 7A and 7B show perspective views of a multiple continuous 45 degree bevel cuts 80. The control line 66 stays constant from the first end 70 of the surface 28 of the material 30 to a second end 72 of the surface 28 of the material 30. The changing deviation of the variable line 68 from further 82 to closer 84 to the control line 66, changes the amount of the slice 78 to be removed. FIG. 7A shows the cut slice 78 being removed from the surface 28 or the material 30. FIG. 7B shows the resultant image 86 with areas of greater intensity 88, where the variable line 68 had maximum deviation from the control line 66. The resultant image 86 also shows area of lesser intensity 90, where the variable line 68 had minimal deviation from the control line 66.

[0054] FIGS. 8A and 8B show alternative embodiments of the present disclosure. FIGS. 8A and 8B show the top and side views of the present disclosure including the various angles, depths and range of motions 74 of the cuttings on the surface 28 of the material 30 that allow for the different intensities depending on the original image 12.

[0055] FIG. 8A shows a first dual 30 degree cut 92, a second dual 30 degree cut 94, and a third dual 30 degree cut 96, at different heights that generate narrow 92, 94 and broad 96 cuts and a relatively lower 92, 94 and greater 96 intensity images. At 30 degrees, the first cut 92 will show a less intense view than the third cut 96.

[0056] FIG. 8B, on the other hand, shows a first dual 45 degree cut 98, a second dual 45 degree cut 100, and a third dual 45 degree cut 102, at different heights that generate narrow 98, 100 and broad 102 cuts and a relatively lower 98, 100 and greater 102 intensity images. At 45 degrees, the first cut 98 will show a less intense view than the third cut 102.

[0057] FIGS. 9A and 9B show the resultant image on the surface 28 of the material 30. FIG. 9A shows a resultant image 104 after CNC cutting of the surface 28 of the material 30. FIG. 9B shows a close up of FIG. 5A. As shown, the wider angle cuts 106 have a greater intensity and show more color than the cuts having a narrower angle 108.

[0058] Similarly, FIGS. 10A and 10B show the resultant image of a face of a person on the surface 28 of the material 30. FIG. 10A shows a resultant image 110 after CNC cutting of the surface 28 of the material 30. FIG. 10B shows a close up of FIG. 10A. As shown, the wider angle cuts 112 have a greater intensity and show more color than the cuts having a narrower angle 114.

[0059] As described herein, the material used in the preferred embodiment is polyester felt and is between 60% and 99% recycled material. Maintenance includes occasional vacuuming to remove particulate matter and air-borne debris or dust. Compressed air can be used to dust off the material in difficult to reach areas and for large assemblies.

[0060] The felt comes in numerous colors, including white, cream, light grey, light brown, brown, matte grey, charcoal, black, yellow, mango, orange, red, lavender, lime, green, light blue and dark blue, and can be manufactured in many other colors and the present disclosure is not limited to these specifications and colors, as these are merely the specifications and colors for the preferred embodiments and alternative embodiments.
