Abstract

The present invention is a an interactive multi-media training system which incorporates text, audio, and video graphics animation and other tools to teach an operator to use a machining or other tool. The training system includes a computer workstation to allow inputs from an operator, computer memory, and a training computer program operating on the computer and having a graphical user interface for interfacing the operator with the workstation and interactively training the operator to operate and perform tasks on the machine tool. The operator can provide inputs to the training system by various input devices such as a keyboard, cursor or mouse. The training system additionally includes interface software operating on the computer for controlling the machine tool and sharing access to and exchange data with the computer memory and a remote station linked to the computer memory for allowing an instructor to monitor and supervise the operator in real time.

Claims

1. A method of training a machine tool trainee to operate a computer controlled machine, while the machine is in an operational mode, the method comprising the steps of:

inputting predetermined operations data into a memory medium, the operations data being representative of the operational steps useful to properly perform a specified task;

comparing the predetermined operations data to trainee operator input data to determine whether the trainee is entering appropriate commands to perform the specified task;

disabling the trainee operation of the machine tool upon determination that the operator input data deviates from the predetermined operations data beyond a predetermined tolerance; and

generating an error signal to advise the trainee that the operator input data is in error when the operator input data deviates from the predetermined operations data beyond the predetermined tolerance.

2. The method as recited in claim 1, further comprising the step of:

enabling operational control of the machine tool after the error signal has been generated, to allow the trainee to again attempt to complete the specified task without error.

3. The method as recited in claim 1, further comprising the step of:

exchanging the operator input data with a remote station such that an instructor monitors and supervises the trainee.

4. The method as recited in claim 2 wherein the trainee is inputting the operator input data with a graphical user interface.

5. The method as recited in claim 4 wherein the graphical user interface further comprises:

(1) displaying a main menu with a plurality of tooling categories, each tooling category having a primary submenu;

(2) selecting one of the plurality of tooling categories with the graphical user interface;

(3) displaying a selected primary submenu with a plurality of tooling operations with the graphical user interface, each tooling operation having a secondary submenu;

(4) selecting one of the plurality of tooling operations with the graphical user interface; and

(5) displaying a selected secondary submenu with a plurality of functional modules with the graphical user interface, each functional module being associated with a tooling task, wherein the functional module is accompanied by sensory media of at least one of video, audio, graphics, preprogrammed animation and text for immediate sensory feedback.

6. The method of claim 5 wherein step (1) further comprises:

displaying a text window for inputting textual information and operator selectable hypertext and a graphical window for inputting graphical information and operator selectable hypergraphics.

7. The method of claim 5 wherein step (5) further comprises:

displaying an operator selectable simulation functional module for viewing a preprogrammed animated sequence of steps replicating said tooling task.

8. The method of claim 5 wherein step (5) further comprises:

displaying an operator selectable example functional module for viewing a preprogrammed video sequence of steps replicating said tooling task.

9. The method of claim 5 wherein step (5) further comprises:

displaying an operator selectable practice functional module for allowing said operator to input and to perform preprogrammed practice simulation steps of said tooling task.

10. The method of claim 5 wherein step (5) further comprises:

displaying an operator selectable error functional modules prompted by preprogrammed events associated with operator error input.

11. The method of claim 5 wherein step (5) further comprises:

displaying an operator selectable walk-through functional module for allowing said operator to examine a preprogrammed sequential simulation of said tooling task.

12. The method of claim 5 wherein step (5) further comprises:

displaying an operator selectable expert functional module for viewing a preprogrammed interactive session of frequently asked questions with text and hypertext to additional information of said tooling task.

13. The method of claim 5 wherein step (5) further comprises:

displaying an operator selectable self-test functional module for allowing said operator to view a preprogrammed interactive testing session of said tooling task.

14. The method of claim 5 wherein step (5) further comprises:

displaying an operator selectable diagram functional module for allowing said operator to view preprogrammed blue prints and images that support learning process of said tooling task.

15. A machine tool training system for a machine tool trainee, comprising:

a machine tool; and

a computer interfaced to said machine tool and having;

training software operative to compare predetermined operations data with operator input data to determine whether the trainee is entering appropriate commands to perform the specified task;

wherein the training software disables operation of the machine tool upon determination that the operator input data deviates from the predetermined operations data beyond a predetermined tolerance, thereby generating an error signal to the trainee to advise the trainee that the operator input data is in error; and

interface software configured to operate the machine tool;

wherein the interface software moves and operates the machine tool solely upon the operator input data being inputted by the trainee.

16. The system of claim 15 wherein the computer further has a memory medium operative to share access to and exchange operator input data with the training software in the computer.

17. The system of claim 16 wherein the memory medium is operative to share access to and exchange operator input data with the interface software in the computer.

18. The system of claim 17 wherein the training software in the computer further comprises a graphical user interface.

19. The system of claim 18 wherein the graphical user interface of the training software further comprises:

a main menu with a plurality of primary training submenus, each primary submenu is associated with a tooling category;

a selected primary submenu with a plurality of secondary training submenus, each secondary submenu is associated with a tooling operation; and

a selected secondary submenu with a plurality of functional modules, each functional module is associated with a tooling task, wherein the functional module is accompanied by sensory media of at least one of video, audio, graphics, preprogrammed animation and text for immediate sensory feedback.

20. The system of claim 18 wherein the training software includes training modules, wherein the training modules consist of menu control buttons, integrated windows, and icons.

21. The system of claim 20 further comprising a remote station for an instructor interfaced to the computer and operative to share access to and exchange the operator data with the memory medium.

22. The system of claim 20 wherein said graphical user interface further comprises an operator selectable practice functional module for allowing said operator to input and perform preprogrammed practice simulation steps of said tooling task.

23. The system of claim 20 wherein said graphical user interface further comprises an operator selectable error functional module prompted by preprogrammed events associated with operator error input.
