Abstract

A power tool control system connected with a drill press provides a system for determining operational settings for the drill press and/or structural factors of a workpiece to be operated upon by the drill press. For instance, the power tool control system may establish a visual indication of the axis of operation of the drill press upon a workpiece and/or determine the thickness, structural composition, and/or moisture content of a workpiece. The determined axis of operation and/or structural factor is utilized to determine the operational settings of the power tool.

Claims

1. A drill press, including a drill bit connected to a motor via a quill assembly, the drill bit for engaging a workpiece seated upon a work table of the drill press, comprising:

a bench column including a first end connected with a head assembly and a second end connected with a stabilizing stand assembly, the bench column further connected with the work table;

a fence assembly; and

a power tool control system connected with the bench column, the power tool control system connected in a position correlating with the work table,

wherein the power tool control system provides a measure of a structural factor of the workpiece for use in determining operational settings of the drill press.

2. The drill press of claim 1, further comprising a dust collection system.

3. The drill press of claim 1, further comprising an adjustable feed handle assembly.

4. The drill press of claim 1, further comprising an adjustable arm.

5. The drill press of claim 1, further comprising a table angular adjustment assembly.

6. The drill press of claim 1, wherein the work table is a milling table.

7. The drill press of claim 1, wherein the work table includes a throat plate.

8. The drill press of claim 1, wherein the work table includes a laser activated section.

9. The drill press of claim 1, further comprising a multi-depth adjustment assembly.

10. The drill press of claim 1, further comprising a stabilizing stand assembly.

11. The drill press of claim 1, further comprising an ergonomic chuck key.

12. The drill press of claim 1, wherein the power tool control system further comprises:

a casing including a receiver, the casing being connected with the drill press; and

a laser mount connected with a laser source for emitting a laser beam, the laser mount for being received by the receiver.

13. The drill press of claim 1, wherein the power tool control system further comprises:

a casing including a first receiver and a second receiver, the casing being connected with the drill press;

a first laser mount connected with a first laser source for emitting a first laser beam, the first laser mount for being received by the first receiver; and

a second laser mount connected with a second laser source for emitting a second laser beam, the second laser mount for being received by the second receiver.

14. The power tool control system of claim 1, further comprising a casing adjustment mechanism.

15. The power tool control system of claim 1, further comprising a laser mount adjustment mechanism.

16. The power tool control system of claim 1, further comprising a laser source adjustment mechanism.

17. The power tool control system of claim 1, further comprising a laser beam adjustment mechanism.

18. A method of operating a drill press, including a work table for engaging a drill bit with a workpiece, comprising:

determining a first distance, the first distance comprising the distance of the work table from a casing connected with a laser source, the casing connected with the drill press;

positioning the workpiece upon the work table;

determining a second distance, the second distance comprising the distance from the casing including the laser source to the workpiece;

calculating the thickness of the workpiece from the determined first and second distances;

providing the established distance data to the user of the drill press;

setting the operational settings of the drill press based on the determined distance data; and

drilling through the workpiece.

19. The method of claim 18, further comprising the step of automatically setting the operational setting of the drill press based on the determined thickness.

20. The method of claim 18, further comprising:

determining a hardness of the workpiece; and

setting the operational settings of the drill press based on the determined hardness of the workpiece.

21. A drill press, including a drill bit connected to a motor via a quill assembly, the drill bit for engaging a workpiece seated upon a work table of the drill press, comprising:

a bench column including a first end connected with a head assembly and a second end connected with a stabilizing stand assembly, the bench column further connected with the work table;

a multi-depth adjustment assembly connected to the head assembly; and

a power tool control system connected with the bench column, the power tool control system connected in a position correlating with the work table,

wherein the power tool control system provides a measure of a structural factor of the workpiece for use in determining operational settings of the drill press.

22. The drill press of claim 21, further comprising a dust collection system.

23. The drill press of claim 21, further comprising an adjustable feed handle assembly.

24. The drill press of claim 21, further comprising an adjustable arm.
