EXPLANATION
Xp : X-axis or an axis parallel to the X-axis
Yp : Y-axis or an axis parallel to the Y-axis
Zp : Z-axis or an axis parallel to the Z-axis
α, β : Rotary axes
Format for Nano smoothing for 5-axis machining is same as that for the
conventional Nano smoothing, but two rotary axes, adding to three basic axes (X,
Y, and Z) and their parallel axes, can be specified as the axis of Nano smooting.
Please see the explanation for Nano smoothing about conditions to enable Nano
smoothing and note.
When Nano smoothing for 5-axis machining and Tool center point control for 5-
axis machining (type I: G43.4) are used together, Tool center point control for 5-
axis machining (G43.4) should be commanded first, and after that Nano
smoothing for 5-axis maching (G05.1 Q3) should be commanded. When they are
canceled, Nano smoothing for 5-axis machining should be canceled (G05.1 Q0)
first, and after that Tool center point control for 5-axis machining should be
canceled (G49).
