Abstract
A method including: a) causing a tool mounted on a machine tool to work on a workpiece, and at least one sensor, which is configured to measure one or more aspects of the tool and/or machine tool, collecting sensor data during said working; b) a measurement device inspecting the part of the workpiece that was worked on at step a) to obtain measurement data; and c) calculating sensor-to-workpiece data calibration information from the sensor data and the measurement data.
Claims16
A method comprising:
- a) causing a tool mounted on a machine tool to work on a workpiece, wherein at least one sensor, which is configured to measure one or more aspects of the tool and/or the machine tool, collects sensor data during the working;
- b) a measurement device inspecting a part of the workpiece that was worked on at step a) to obtain measurement data;
- and
- c) calculating sensor-to-workpiece data calibration information from the sensor data and the measurement data.
The method as claimed in 11, wherein the at least one sensor is located toward an end of the tool holder that is proximal the tool insert.
A method of inferring measurement data about a workpiece worked on by a tool mounted on a machine tool, the method comprising, in any suitable order:
- a) taking 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 whilst the workpiece was being worked on by the tool;
- and
- b) using sensor-to-workpiece data calibration information, which is for a particular combination of the tool, the workpiece, and the machine tool, to infer information about the workpiece from the sensor data.
