Fine spline interpolation
The spline interpolation automatically creates a curve that smoothly traces specified points, and thus enables a high-speed and high-accuracy machining for free shapes along smoothly curved tool path. The modal preparatory function G61.2 is used to select a geometry compensation mode which is in general equivalent to G61.1 with a particular difference in that all blocks of G1 (linear inter- polation) are processed as those of fine spline interpolation. This function is especially useful in applying fine spline interpolation to a programm with microsegment blocks created by a CAM.
G06.1 is modal (group 01) — it stays in effect until another code of the same group replaces it.
