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.

Release Note

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,
