Abstract

According to one aspect, a system that includes an RFID (Radio Frequency Identification) tag reader, a plurality of cutting dies, a plurality of RFID tags connectable to the corresponding cutting dies, and a controller including a computer usable program code including program instructions for scanning instruction the RFID tag reader to scan the RFID tags, updating respective piece counts corresponding to specific shapes provided by some of the plurality of cutting dies, and displaying the respective piece counts.

Claims

1. A method comprising the steps of:

providing at least one cutting die with an RFID (Radio Frequency Identification) tag containing information related to the identity of the die on a hide;

scanning the RFID tag;

updating a count associated with the die; and

determining and displaying the difference between the maximum count and the count associated with a die.

2. A method according to claim 1 further comprising:

determining whether or not the count exceeds a predefined maximum count; and

, cutting the hide with the die if the maximum count has not been exceeded.

3. A method according to claim 2 further comprising:

providing a plurality of cutting dies, at least one of the cutting dies having a shape that is different from another cutting die, the cutting dies having RFID tags;

scanning the RFID tags of each of the plurality of dies; and

updating a count associated with each of the plurality of dies.

4. A method according to claim 2 further comprising determining whether an order requiring a quantity of pieces to be cut by the die is complete.

5. A method according to claim 2 further comprising storing a count related to a quantity of pieces cut by a die.

6. A method according to claim 2 further comprising:

re-selecting a die so as to cut a required piece to fill an order; and

scanning the re-selected die.

7. A method according to claim 2 further comprising shielding an area from Radio Frequency (RF) interference within which an RFID tag on a die can be scanned.

8. A method according to claim 1 further comprising:

providing an RFID tag containing information related to the area of the hide;

scanning the RFID tag to determine the hide area.

9. A method according to claim 8 further comprising:

determining the area of pieces cut by the dies on the hide; and

, comparing the area of the hide with the area cut by the dies.

10. A method according to claim 8 further comprising comparing a yield of the hide to a desired yield of the hide.

11. A system comprising:

an RFID (Radio Frequency Identification) tag reader;

a plurality of cutting dies;

a plurality of RFID tags connectable to the corresponding cutting dies; and

a controller including a computer usable program code including program instructions for;

scanning instruction the RFID tag reader to scan the RFID tags;

updating respective piece counts corresponding to specific shapes provided by some of the plurality of cutting dies; and

displaying the respective piece counts.

12. A system according to claim 11 further comprising Radio Frequency (RF) shielding defining an area within which the RFID tags can be scanned.

13. A system according to claim 11 further comprising a display for displaying respective piece counts or other information.

14. A system according to claim 11 further comprising a spacer between each die and its respective RFID tag.
