Abstract

A tool for machining an object including a first part including a rotatable member that is rotatable to cause rotation of a machine tool, a second part, a joint coupling the first part and the second part to enable relative movement between the first part and the second part, and a sensor to sense an object to be machined.

First claim

The invention claimed is:

1. An apparatus for inspecting a blade within a turbine engine, the apparatus comprising:
a tool configured to perform machining on the blade;
a sensor of the tool, the sensor being configured to sense a shape of the blade within the turbine engine;
a first controller and a second controller, wherein the second controller is configured to receive data from the sensor that indicates the shape, the first controller is configured to determine a control of the tool using the received data, and second controller is further configured to provide a control signal to cause the control of the tool; and
an actuator configured to receive the control signal from the controller and to control the tool using the control signal, wherein
the first controller is configured to communicate with the second controller by one of intercontinental data cables and satellite communications.

2. The apparatus as claimed in claim 1 , wherein the tool comprises: a Raman spectrometer; or an imaging device; or an Ultraviolet (UV) inspection device.

3. The apparatus as claimed in claim 1 , wherein the first controller is configured to determine whether relative movement between the tool and the blade is required to enable machining of the blade by the tool.

4. The apparatus as claimed in claim 1 , wherein the first controller is configured to determine the control of the tool by:
determining whether the shape of the blade differs from a predetermined shape above a threshold level using the received data; and
determining a machining path for the tool to bring the shape of the blade at least towards conformity with the predetermined shape.

5. The apparatus as claimed in claim 1 , wherein the first controller is configured to:
determine whether the shape of the blade after machining differs from a predetermined shape above a threshold level using the received data; and
determine a further machining path for the tool to bring the shape of the blade further towards conformity with the predetermined shape.

6. The apparatus as claimed in claim 1 , wherein the second controller is configured to operate without user intervention.

7. The apparatus as claimed in claim 1 , wherein the first controller is configured to communicate with multiple second controllers at a time in a multi-device configuration.

8. The apparatus as claimed in claim 1 , wherein the second controller is located in closer proximity to the tool than the first controller.

9. The apparatus as claimed in claim 1 , wherein the second controller is configured to provide the data to the first controller.

10. The apparatus as claimed in claim 9 , wherein the first controller is configured to determine a machining path for the tool.

11. The apparatus as claimed in claim 10 , wherein the second controller is configured to convert the machining path into control signals to control the tool.

12. The apparatus as claimed in claim 1 , wherein the first controller is configured to generate a machining path using the received data.

13. The apparatus as claimed in claim 12 , wherein the second controller is configured to receive the machining path from the first controller.

14. The apparatus as claimed in claim 13 , wherein the second controller is configured to convert the machining path into control signals to control the tool.

15. An apparatus for inspecting an object, the apparatus comprising:
a tool configured to perform machining on the object;
a sensor of the tool, the sensor being configured to sense the object; a first controller and a second controller, wherein the second controller is configured to receive data from the sensor, the first controller is configured to determine a control of the tool using the received data, and the second controller is further configured to provide a control signal to cause the control of the tool; and
an actuator configured to receive the control signal from the second controller and to control the tool using the control signal, wherein
the first controller is configured to communicate with the second controller by one of intercontinental data cables and satellite communications.
