Abstract

A machine tooling system is provided, comprising a tooling machine having a plurality of adjustable cutting units installed at various locations therein, a collet for holding a workpiece to be tooled, and a presetter machine for adjusting the adjustable cutting units to within prescribed specifications when the adjustable cutting units are detached from the tooling machine. Each of the adjustable cutting units may be precisely positioned to contact the workpiece to be tooled, and each is provided with an identification device attached thereto. The identification devices provide (i) location information identifying a particular location on the tooling machining for which the cutting unit is precisely adjusted and (ii) adjustment information including the adjustment parameters at which the adjustable cutting unit is preset. A cutting unit identification subsystem reads and stores the location information and the adjustment information provided by the identification devices.

Claims

1. A machine tooling system, comprising:

a tooling machine having a plurality of adjustable cutting units installed therein at various locations on the tooling machine, each of said adjustable cutting units being positionable to contact a workpiece to be tooled and having an identification device attached thereto, each of said identification devices providing location information relating the adjustable cutting unit to which it is attached to a particular location on said tooling machine;

a collet for holding a workpiece to be tooled,

a presetter machine for adjusting said adjustable cutting units to within prescribed specifications when said adjustable cutting units are detached from said tooling machine; and

a cutting unit identification subsystem for storing said location information provided by said identification devices.

2. The device of claim 1, wherein said identification device is a semiconductor memory device and said cutting unit identification subsystem reads said location information contained within said memory device.

3. The device of claim 2,/ wherein said semiconductor memory device is optically scannable and said cutting unit identification subsystem includes (i) a non-contact optical scanner for reading the location information contained within said optically scannable memory device and (ii) subsystem memory for storing said location information.

4. The device of claim 2, wherein said semiconductor memory device also stores information relating to the operational life of the adjustable cutting unit to which it is attached.

5. The device of claim 2, wherein said identification device contains adjustment information relating to the adjustment settings of the adjustable cutting unit to which it is attached.

6. The device of claim 5, wherein each of said adjustable cutting units includes a removable tooling cartridge having an adjustment mechanism.

7. The device of claim 5, wherein said adjustable cutting unit is provided with at least one set screw.

8. The device of claim 5, wherein the workpiece to be tooled is a metal rod-like blank.

9. The device of claim 8, wherein the workpiece to be tooled is used to form a shell of a spark plug.

10. A method of presetting adjustable blade cartridges in a tooling machine having a plurality of adjustable blade cartridges installed therein at various locations on the tooling machine, the method comprising the steps of:

attaching an identification device to one of said plurality of adjustable cutting units;

installing said adjustable cutting unit in one of said various locations the tooling machine;

manually adjusting said adjustable cutting unit so that a workpiece tooled by said blade cartridge is within prescribed specifications;

removing said adjustable cutting unit from said tooling machine and installing said adjustable cutting unit in a presetting machine; and

registering in said identification device location information relating to the particular location on said tooling machine from which said adjustable cutting unit was removed.

11. The method of claim 10, further comprising the steps of:

registering in said identification device adjustment information relating to adjustment settings of the adjustable cutting unit to which it is attached;

reading from said identification device and storing in a memory device said location information and said adjustment information;

removing said adjustable cutting unit from said presetter machine and installing a second adjustable cutting unit into said presetter machine;

recalling said location information and said adjustment information from said memory device;

adjusting said second adjustable cutting unit on said presetter machine corresponding to said adjustment information; and

installing said second adjustable cutting unit on said tooling machine corresponding to said location information.

12. The method of claim 11, wherein said identification device is an optically scannable semiconductor device and a non-contact optical scanner is used for reading said location information and said adjustment information from said optically scannable memory device.

13. The method of claim 11, wherein said identification device also stores information relating to the operational life of the adjustable cutting unit to which it is attached.

14. The method of claim 11, wherein each of said adjustable cutting units includes a removable tooling cartridge having an adjustment mechanism.

15. The method of claim 14, wherein the workpiece to be tooled is a metal rod-like blank.

16. The method of claim 15, wherein the workpiece to be tooled is used to form a shell for a spark plug.
