Overview

Task

The aim of this functionality is to reduce machine oscillations caused by frequent program-related acceleration and deceleration processes. The functionality smooths the planned path velocity curve while taking a predefined criterion into consideration.

Effectiveness

Smoothing the path velocity curve or reducing acceleration and deceleration processes is achieved by cross-block adjustment of the planned maximum path velocities. The maximum path velocities are adjusted by reducing them, which can result in a longer machining time.

Specifying the smoothing criterion (productivity factor) defines

• the degree of smoothing as well as
• the maximum machining time that is tolerable.

This functionality is available as of CNC Build V3.01.3079.21.

Parameterisation

In order to use this functionality, it must be enabled by the parameter P-CHAN-00600.

Programming

The functionality is parameterised by the NC command #LAH[…].
