1. A method, comprising:

a) causing a tool mounted on a machine tool to process a workpiece, wherein at least one sensor configured to measure one or more aspects of the tool and/or machine tool collects sensor data during the process;

b) the measuring device inspects the portion of the workpiece processed in step a) to obtain measurement data; and

c) and calculating sensor-to-workpiece data calibration information according to the sensor data and the measurement data.

2. The method of claim 1, further comprising inferring information about a workpiece using the sensor-to-workpiece data calibration information and sensor data collected during the processing of the workpiece.

3. The method of claim 1 or 2, wherein the workpiece of step a) is one of a series of nominally identical workpieces to be processed, and wherein, for at least one other workpiece in the series, information about the at least one other workpiece is inferred from the sensor-to-workpiece data calibration information and sensor data obtained during processing thereof.

4. The method of claim 1 or 2, wherein the method comprises:

d) processing the same or nominally the same workpiece using the same or nominally the same tool and the same or nominally the same machine tool as used in step a), an

e) Using the sensor-to-workpiece data calibration information, inferring information about the workpiece from sensor data collected during step d) by the same sensor or nominally the same sensor as used in step a).

5. The method of any of claims 2 to 4, wherein the information about the workpiece inferred from the sensor data comprises measurement data.

6. The method of any of claims 2 to 5, further comprising using the inferred information about the workpiece to adjust subsequent processing of the workpiece or a subsequent nominally identical workpiece.

7. The method of any preceding claim, wherein the sensor data comprises at least one of: vibration, deflection, and/or load.

8. The method of any preceding claim, wherein the measurement data and/or the inferred information comprises at least one of: the position, size, surface roughness, surface waviness of the workpiece.

9. The method of any preceding claim, wherein the processing of the workpiece comprises at least one of: cutting, drilling, grinding, polishing, turning, reaming and milling.

10. The method of any preceding claim, wherein the tool comprises the at least one sensor.

11. The method of claim 10, wherein the tool includes a tool insert and a tool body, the tool insert being mounted to the machine tool apparatus via the tool body, and wherein the tool body includes the at least one sensor.

12. The method of claim 11, wherein the at least one sensor is positioned toward an end of the toolholder proximate the cutting insert.

13. A method according to any preceding claim, wherein step b) is performed by a measuring device mounted on the machine tool.

14. A method according to any preceding claim, wherein the measurement device comprises a measurement probe, such as a contact measurement probe, for measuring a dimensional attribute of the workpiece.

15. The method of any preceding claim, wherein step c) comprises adjusting previously determined sensor-to-workpiece data calibration information based on the sensor data and the measurement data.

16. A method of inferring measurement data relating to a workpiece being processed by a tool mounted on a machine tool, the method comprising, in any suitable order:

a) obtaining sensor data obtained by at least one sensor, the sensor data relating to one or more properties of the tool and/or the machine tool when the workpiece is processed by the tool; and

b) calibrating information to workpiece data using sensors configured for the particular tool in combination with a workpiece and a machine tool, inferring information about the workpiece from the sensor data.
