Machine tool acceleration

A method of controlling movement of a processing head of a machine tool, the method comprising:

• monitoring a position of the processing head along a first coordinate direction;
• monitoring movement of the processing head along a second coordinate direction different from the first coordinate direction;
• and
• limiting the change in acceleration of the processing head along the second coordinate direction to a value below a predetermined maximum value, wherein the predetermined maximum value decreases as a function of the position of the processing head along the first coordinate direction.

A machine tool comprising:

• a processing head that is displaceable along a first coordinate direction and along a second coordinate direction that is different from the first coordinate direction;
• a sensor adapted to monitor the position of the processing head along the first coordinate direction;
• a memory adapted to store data for defining a maximum allowable value of an acceleration of the processing head in the second coordinate direction;
• and
• a processor adapted to limit the acceleration of the processing head in the second coordinate direction to a value lower than a maximum allowable value, wherein the maximum allowable value is determined from the data stored in the memory and from the position of the processing head along the first coordinate direction, and wherein the maximum allowable value decreases as a function of the position of the processing head along the first coordinate direction.

A computer program product, tangibly stored on a machine-readable medium, for controlling the movement of a processing head of a machine tool, the computer program product comprising instructions for causing a processor to:

• receive information about a position of the processing head along a first coordinate direction;
• receive information about movement of the processing head along a second coordinate direction that is different from the first coordinate direction;
• and
• limit an acceleration of the processing head along the second coordinate direction to a value below a predetermined maximum value, wherein the predetermined maximum value decreases as a function of the position of the processing head along the first coordinate direction.
