Abstract

Disclosed is an automated cutting of a cylindrical workpiece. According to a method a cutting device is positioned, a motor is activated to rotate about an axis to cut the cylindrical element, and cutting the cylindrical element. Further disclosed is an apparatus and system to automate the cutting of a cylindrical workpiece.

First claim

What is claimed:

1. A method for dimensioning a segment of a cylindrical element comprising:
positioning a cutting device against an interior diameter of the segment of the cylindrical element;
activating a motor to rotate the cutting device about an axis to cut the cylindrical element;
cutting the cylindrical element by way of the motor about the axis; and
securing the cutting apparatus to the cylindrical element,
wherein upon activation of the motor, the cutting device is guided along a circumferential direction against the interior diameter of the segment,
wherein the securing includes attaching a first face plate of the cylindrical element to a second face plate of the cutting device using a plurality of clamps.

2. The method as claimed in claim 1 , wherein the securing includes adjusting a clamp attached to the second face plate of the cutting device to the first face place of the cylindrical element.

3. The method as claimed in claim 1 , further comprising adjusting the cutting device to a cutting depth along an axial direction.

4. The method as claimed in claim 1 , further comprising adjusting the cutting device to a cutting width along a radial direction.

5. The method as claimed in claim 1 , further comprising adjusting a torch tip angle for a torch tip.

6. The method as claimed in claim 5 , wherein the torch tip angle is adjusted prior to the positioning.

7. The method as claimed in claim 5 , wherein the torch tip angle is positioned 90° to a cutting surface.

8. The method as claimed in claim 1 , further comprising adjusting the speed of the motor.

9. The method as claimed in claim 1 , wherein the segment has a semi-circular cross-section, wherein the motor is operated to rotate the radially extending arm by 180 degrees.

10. A system comprising:
a cutting device positioned against an interior diameter of a segment of a cylindrical element;
a motor rotatable about an axis of the cylindrical element, and
an arm extending in a radial direction of the cylindrical element that couples the motor with the cutting device,
wherein upon activation of the motor, the cutting device is guided along a circumferential direction against the interior diameter of the segment,
wherein a plurality of clamps are used to attach a first face plate of the cylindrical element to a second face plate of the cutting device.
