Abstract
A method for moving a tool of a CNC machine over a surface, wherein the CNC machine is provided with a sensor unit, comprising the steps of: (a) moving the tool over the surface in a predetermined direction and/or with a predetermined velocity and/or along a predetermined path, (b) treating the surface by the tool in accordance with a predetermined value of a treatment parameter, (c) determining, by the sensor unit, a response value indicating a response of the tool to treating the surface and/or to being pressed to the surface, and (d) determining a new direction and/or a new velocity and/or a new path and/or a new value for the treatment parameter based on the response value.

A method for moving a tool of a CNC machine over a surface, wherein the CNC machine is provided with a sensor unit, the method comprising the steps of:
- (a) driving the tool over the surface in a predetermined direction and/or along a predetermined path;
- (b) treating the surface by the tool in accordance with a predetermined value of a treatment parameter;
- (c) determining, by the sensor unit, a response value indicating a response of the tool to the treating of the surface, and deriving a model of the surface based on the response value, wherein the model describes a shape of at least a part of the surface and is derived from data obtained from the sensor unit while the tool is driven over the surface, the data comprising data indicating a deflection of the tool or a force experienced by the tool when treating the surface;
- and
- (d) determining a new direction and/or a new path based on the response value and on the model, and adapting the treating of the surface to working conditions which are encountered by the tool by changing direction of driving over the surface laterally with respect to the predetermined direction and/or the predetermined path, so as to treat the surface along a direction and/or a path that are/is different from the predetermined direction and/or path, such that a resulting treated path is different than the predetermined path.
A CNC machine, which is configured to move a tool over a surface, comprising:
- a driving unit configured to drive the tool in a predetermined direction and/or along a predetermined path;
- a treatment unit configured to treat the surface by the tool in accordance with a predetermined value of a treatment parameter;
- a sensor unit configured to determine a response value indicating a response of the tool to the treating of the surface, wherein the CNC machine is configured to derive a model of the surface based on the response value, and wherein the model describes a shape of at least a part of the surface and is derived from data obtained from the sensor unit while the tool is driven over the surface, the data comprising data indicating a deflection of the tool or a force experienced by the tool when treating the surface;
- and
- a decision unit configured to determine a new direction and/or a new path based on the response value and on the model, and to adapt the treatment of the surface to working conditions which are encountered by the tool by changing direction of driving over the surface laterally with respect to the predetermined direction and/or the predetermined path, so as to treat the surface along a direction and/or a path that are/is different from the predetermined direction and/or path, such that a resulting treated path is different than the predetermined path.
A method for moving a tool of a CNC machine over a surface, wherein the CNC machine is provided with a sensor unit, the method comprising the steps of:

- (b) treating the surface by the tool in accordance with a predetermined value of a treatment parameter;
- (c) determining, by the sensor unit, a response value indicating a response of the tool to the treating of the surface, and deriving a model of the surface based on the response value, wherein the model describes a shape of at least a part of the surface and is derived from data obtained from the sensor unit while the tool is driven over the surface;
- and
- (d) determining a new direction and/or a new path based on the response value and on the model, and adapting the treating of the surface to working conditions which are encountered by the tool by changing direction of driving over the surface laterally with respect to the predetermined direction and/or the predetermined path, so as to treat the surface along a direction and/or a path that are/is different from the predetermined direction and/or path, such that a resulting treated path is different than the predetermined path;
- wherein the tool comprises a hammer, and the method comprises sensing by the sensor unit counteracting forces and deflections experienced by the hammer in three directions perpendicular to each other, and determining by the CNC machine an angle between a direction of a hammer stroke and the surface based on the sensed forces and deflections.
