Function
The function for five-axis spline interpolation smoothes the path of the tool as well as the
change in tool attitude in the mode of tool tip point control. Linear interpolation commands
given in the mode of this function are used to draw a curve through the specified ending
points so that abrupt deceleration and acceleration between linear-interpolation blocks is
dispensed with and, as a result, the machining time considerably reduced. As for the
control of tool attitude, angle commands for the rotational axes concerned are
correspondingly spline-interpolated in order to make the angular movements continuous
and smooth.

Note: The function of specifying the tolerance (of chord error) is available, on condition that it
is enabled by a parameter setting as shown below:

2. Notes
 The function for five-axis spline interpolation cannot work until, in the mode of G61.2,
tool tip point control is turned ON (with G43.4 or G43.5), and high-speed smoothing
control is made valid (Geometry compensation ON, G05P2 given, and parameter
F3 = 1). Fine spline interpolation is applied when tool tip point control, workpiece setup
error correction, and inclined-plane machining are all inactive.
The table below shows how G01 blocks under G61.2 are processed under various
modal states.
