Overview

	This function is an additional option requiring a license.

Task

Machine vibrations can have a negative impact on the machining results of a machine tool.

The FIR filter function (Finite Impulse Response filter) achieves the following:

Smooths setpoint curves at axis level.
Reduces the excitation of machine vibrations.
Is simple and reliable to use by specifying a maximum permitted tolerance.

Improves surface finish especially in free-form surface machining.

	This function is available as of CNC Build V3.1.3075.02

Programming and parameterisation

The function can be parameterised and enabled

both in the axis lists
and in the #FILTER programming command in the NC program,

provided a filter type (P-AXIS-00586) is configured for the particular axis.

Mandatory note on references to other documents

For the sake of clarity, links to other documents and parameters are abbreviated, e.g. [PROG] for the Programming Manual or P-AXIS-00001 for an axis parameter.

For technical reasons, these links only function in the Online Help (HTML5, CHM) but not in pdf files since pdfs do not support cross-linking.
