Abstract

Claims (42)

1. A tooling system for performing an operation on a work piece, the tooling system comprising:

a drive unit;

a tool member removably attached to the drive unit and configured to engage with the work piece;

first and second targets that are visibly positioned on the tool member, the first and second targets being visibly distinct;

a vision system associated with the drive unit and configured to capture an image of each of the first and second targets when the tool member is attached to the drive unit; and

a controller configured to control a first aspect of the drive unit based on the image of the first target captured by the vision system and to control a second aspect of the drive unit based on the image of the second target captured by the vision system;

the drive unit configured to rotate the tool member such that each of the first and second targets are visible to the vision system.

2. The tooling system of claim 1 , wherein the first aspect of the drive unit controls rotation of a mount of the drive unit that attaches to the tool member.

3. The tooling system of claim 1 , wherein the second aspect of the drive unit is a rotational speed of a mount of the drive unit that attaches to the tool member.

4. The tooling system of claim 1 , wherein the vision system includes a single camera with a viewing zone that extends over a limited section of the tool member, with the drive unit configured to rotate the tool member such that each of the first and second targets move through the viewing zone.

5. The tooling system of claim 1 , wherein tine first and second targets are positioned at different locations on the tool member that are located at different distances from the drive unit, the vision system including separate first and second cameras each with different focal lengths with the first camera including a first focal length to capture the image of the first target and the second camera including a second focal length to capture the image of the second target.

6. The tooling system of claim 1 , wherein the vision system and the drive unit are positioned within a single housing.

7. The tooling system of claim 1 , wherein the controller identifies the first and second targets based on the images of the first and second targets captured by the vision system when the tool member is stationary.

8. The tooling system of claim 1 , wherein the first and second targets are separate elements that are attached to the tool member.

9. The tooling system of claim 1 , wherein the drive unit is configured to be stationary prior to the controller identifying the first and second targets.

10. The tooling system of claim 1 , wherein the controller is configured to rotate the tool member after the images of the first and second targets are captured by the vision system and the first and second targets are identified.

11. The tooling system of claim 1 , wherein the drive unit comprises a motor.

12. A tooling system for performing an operation on a work piece, the tooling system comprising:

a motor;

a tool member removably attached to the motor and configured to engage with the work piece;

targets that are visibly positioned on the tool member with each of the targets being visibly distinct;

a camera configured to capture an image of each of the targets when the tool member is attached to the motor; and

a control circuit that controls the motor based on the images of the targets captured by the camera;

wherein the camera includes a viewing zone that extends over a limited section of the tool member, with the motor configured to rotate the tool member such that each of the targets move through the viewing zone.

13. The tooling system of claim 12 , wherein the camera and the motor are positioned within a common housing.

14. The tooling system of claim 12 , wherein each of the targets are separate elements that are attached to the tool member.

15. The tooling system of claim 12 , wherein the control circuit is configured to rotate the tool member after the image of a first one of the targets is captured by the camera and the first one of the targets is identified.

16. A tooling system for performing an operation on a work piece, the tooling system comprising:

a motor;

a tool member;

targets that are visibly positioned on the tool member;

a vision system configured to capture images of the targets; and

a control circuit configured to:

receive a first image from the vision system of a first one of the targets when the tool member is rotated by the motor to a first rotational position;

identify the first target;

determine whether the tool member is proper for the operation on the work piece;

receive a second image from the vision system of second one of the targets when the toot member is rotated by the motor to a second rotational position;

identify the second target; and

determine one or more operating parameters for the motor based on the identified second target.

17. The tooling system of claim 16 , wherein the control circuit is further configured to prevent operation of the motor after determining based on the identified first target that the tool member is not proper for the operation on the work piece.

18. The tooling system of claim 16 , wherein the vision system comprises a single camera that captures the images of the targets.

19. The tooling system of claim 16 , wherein the vision system comprises a first camera that captures the first image and a second camera that captures the second image.
