Abstract

A method and apparatus to verify that proper tooling has been installed in a cable preparation apparatus and/or to calibrate the tooling prior to running the cable preparation apparatus with a cable inserted therein. The method includes: inserting a reference device between blades of the cable preparation device; moving the blades inward toward the reference device until the blades engage the reference device; collecting data to determine when the blades engage the reference device; and comparing the collected data of the blades to an expected range of data of the reference device, wherein if the collected data of the blades does not conform to the expected range of data of the reference device the tooling is not validated, and the apparatus alerts the user.

First claim

The invention claimed is:

1. A method to verify that proper tooling has been installed in a cable preparation apparatus prior to running the cable preparation apparatus with a cable inserted therein, the method comprising:
inserting a reference device between braid cutting wheels and insulation cutting blades of the cable preparation device;
moving the braid cutting wheels inward toward the reference device until the braid cutting wheels engage the reference device;
monitoring the current needed to move the braid cutting wheels to determine when the braid cutting wheels engage the reference device;
moving the insulation cutting blades inward toward the reference device until the insulation cutting blades engage the reference device;
monitoring the current needed to move the insulation cutting blades to determine when the insulation cutting blades engage the reference device;
collecting data to determine when the blades engage the reference device; and
comparing the collected data of the blades to an expected range of data of the reference device to verify that the proper tooling has been installed in the cable preparation apparatus.

2. The method as recited in claim 1 , wherein if the collected data of the braid cutting wheels and the insulation cutting blades does not conform to the expected range of data of the reference device the tooling is not validated, and the apparatus alerts the user.

3. The method as recited in claim 1 , wherein the reference device is a mandrel which has a known diameter.

4. The method as recited in claim 1 , comprising:
inserting the mandrel through an opening in a blade control mechanism of the cable preparation apparatus.

5. The method as recited in claim 4 , wherein the braid cutting wheels and the insulation cutting blades are mounted on blade control arms which are mounted on the blade control mechanism of the cable preparation apparatus.

6. The method as recited in claim 1 , wherein as the braid cutting wheels and the insulation cutting blades contact the reference device, the current needed to move the braid cutting wheels and the insulation cutting blades is increased, allowing a controller of the cable preparation apparatus to recognize that the braid cutting wheels and the insulation cutting blades have contacted the reference device.

7. The method as recited in claim 1 , wherein as the braid cutting wheels and the insulation cutting blades contact the reference device, the encoders of the cable preparation apparatus send position data to a controller of the cable preparation apparatus.

8. The method as recited in claim 1 , comprising:
moving the braid cutting wheels and the insulation cutting blades under low torque toward the reference device until the braid cutting wheels and the insulation cutting blades engage the reference device.

9. A method to calibrate the positioning of tooling in a cable preparation apparatus prior to running the cable preparation apparatus with a cable inserted therein, the method comprising:
i) inserting a reference device between braid cutting wheels and insulation cutting blades of the cable preparation device;
ii) moving the braid cutting wheels inward toward the reference device until the braid cutting wheels engage the reference device;
iii) collecting data to determine when the braid cutting wheels engage the reference device;
iv) moving the braid cutting wheels away from the reference device;
v) moving the insulation cutting blades inward toward the reference device until the insulation cutting blades engage the reference device;
vi) collecting data to determine when the insulation cutting blades engage the reference device;
vii) moving the insulation cutting blades away from the reference device;
viii) repeating steps ii) through vii) at least once;
ix) averaging the data collected; and
x) recording the average collected data to calibrate the braid cutting wheels and the insulation cutting blades.

10. The method as recited in claim 9 , wherein the reference device is a mandrel which has a known diameter.

11. The method as recited in claim 10 , wherein the braid cutting wheels and the insulation cutting blades are mounted on blade control arms which are mounted on a blade control mechanism of the cable preparation apparatus.

12. The method as recited in claim 9 , comprising:
monitoring the current on motors which drive the braid cutting wheels and the insulation cutting blades to detect when the braid cutting wheels and the insulation cutting blades have encountered an object.

13. The method as recited in claim 9 , comprising:
monitoring the position of the braid cutting wheels and the insulation cutting blades with encoders.

14. The method as recited in claim 9 , comprising:
monitoring the current on motors which drive the braid cutting wheels and the insulation cutting blades to detect when the braid cutting wheels and the insulation cutting blades have encountered an object; and
monitoring the position of the braid cutting wheels and the insulation cutting blades with encoders.

15. The method as recited in claim 9 , comprising:
moving the braid cutting wheels and the insulation cutting blades under low torque toward the reference device until the braid cutting wheels and the insulation cutting blades engage the reference device.
