Abstract

A portable EDM device and system thereof for producing calibration reflectors on a pipe includes a base mountable on the pipe, a motor mounted on the base, a cutting tool operably connected to the motor, an electrode operably connected to the cutting tool, a power source mounted on the base and operably connected to the electrode and operably connectable to the pipe, and a source of dielectric fluid mounted on the base. The power source is configured to electrically discharge a voltage from the electrode to the pipe to remove material from the pipe. The source of dielectric fluid is in fluid communication with the pipe to remove the material removed from the pipe.

Claims (29)

1. A portable EDM system for producing calibration reflectors on a pipe, the system comprising:

a base mountable on the pipe;

a cutting tool;

a motor operably connected to the cutting tool for moving the cutting tool in a preselected pattern;

an electrode operably connected to the cutting tool;

a power source operably connected to the electrode and operably connectable to the pipe, the power source being configured to electrically discharge a voltage from the electrode to the pipe to remove material from the pipe; and

a source of dielectric fluid in fluid communication with the pipe to remove the material removed from the pipe;

wherein one or more of the motor, the power source, and the source of dielectric fluid is mounted on the base.

2. The portable EDM system of claim 1 , further comprising a controller in communication with the motor, the source of dielectric fluid, and the power source.

3. The portable EDM system of claim 1 , wherein the source of dielectric fluid comprises,

a dielectric fluid reservoir containing a dielectric fluid,

a dielectric fluid pump through which the dielectric fluid can be pumped,

a conduit through which the dielectric fluid can be transferred from the dielectric fluid pump, and

a nozzle through which the dielectric fluid can be dispensed to the pipe.

4. The portable EDM system of claim 1 , further comprising a support on a surface of the base, the support being sized and configured to mount the portable EDM system onto the pipe.

5. A portable EDM device for producing calibration reflectors on a pipe, the portable EDM device comprising:

a base mountable on the pipe;

a motor mounted on the base;

a cutting tool operably connected to the motor;

an electrode operably connected to the cutting tool;

a power source mounted on the base and operably connected to the electrode and operably connectable to the pipe, the power source being configured to electrically discharge a voltage from the electrode to the pipe to remove material from the pipe; and

a source of dielectric fluid mounted on the base and in fluid communication with the pipe to remove the material removed from the pipe.

6. The portable EDM device of claim 5 , wherein the source of dielectric fluid comprises,

a dielectric fluid reservoir containing a dielectric fluid,

a dielectric fluid pump through which the dielectric fluid can be pumped,

a conduit through which the dielectric fluid can be transferred from the dielectric fluid pump, and

a nozzle through which the dielectric fluid can be dispensed to the pipe.

7. The portable EDM device of claim 5 , further comprising a controller mounted on the base and in communication with the motor, the power source, and the source of dielectric fluid, the controller being configured to provide control signals to control the discharge of the voltage from the electrode, to control an operation of the motor, and to control a flow of dielectric fluid from the source of dielectric fluid.

8. The portable EDM device of claim 5 , further comprising a support located on the base, the support being configured to accommodate on outer surface of the pipe on which the portable EDM device is mounted.
