Overview
When a desired sculptured surface is approximated by minute segments, Nano
smoothing function generates a smooth curve inferred from the programmed
segments and performs necessary interpolation.
In the conventional Nano smoothing, only the three basic axes (X, Y, and Z) or
their parallel axes can be specified as the axis of Nano smooting. On the other
hand, in Nano smoothing for 5-axis machining, two rotary axes, besides the three
basic axes (and their parallel axes), can also be specified. Much smoother surface
is realized by 5-axis machining with rotary axes.
Moreover Nano somoothing for 5-axis machining can be used during Tool center
point control for 5-axis machining (type I: G43.4). And according to this, the same
program can be used even if tool length is changed by tool change.
This feature is an option, and the other option Nano smoothing is also needed.
Command points
Smooth curve is generated from
command points and interpolated.
And tool center point moves on the
generated smooth curve.
Tool center point
Tool length
compensation
Machine position of tool moves so that
it is distant from the path of tool cente
r
point by tool length compensation.
