A method for checking positioning accuracy of a CNC machine with a machine tool head and a machine table using an x, y, z coordinate system, the method comprising:

Method and system for checking positioning accuracy of a CNC machine

A method of determining a positioning error of a CNC machine is provided and an system thereof. A calibration element is placed within the CNC machine. A first sensor reading is taken of the calibration element. A second sensor reading is taken and the sensor is moved in a manner that the difference between the first and second sensor data decreases until the difference becomes less or equal to a pre-determined threshold value. A positioning error of the tool head is determined based on the movement of the sensor.

System and method for error correction for CNC machines

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.
