NURBS interpolation
Machine-specific. This G-code reference is specific to the Mazak INTEGREX e-670H / e-670H-S with the MAZATROL SmoothX control (EIA/ISO programming manual H747PB0030E). G-code availability depends on fitted options, and groups and behaviour differ between Mazak models and control generations — verify against the manual for your own machine before programming with any code.
What it does
Cylindrical interpolation refers to a function by which the cylindrical surface of a workpiece can be machined according to a program prepared on its development plane. This function is among others very efficient in the creation of a cam grooving program.
G06.2 is modal (group 01) — it stays in effect until another code of the same group replaces it.

- The single-block stop only occurs between blocks with different knots.
