G06.2: NURBS interpolation

Interpolation of NURBS (Non-Uniform Rational B-Spline) curves directly in the control, reducing block points and improving smoothness.

For reference only: syntax changes with the control, the post-processor and the machine parameters. Check the official manual and run a simulation before cutting. Legal notice.

Parameters

P: Grado de la curva NURBS (P3 = cúbica).
K: Valores de nudo (uno por bloque).
X Y Z: Puntos de control. · mm
R: Peso del punto de control.
F: Avance de corte. · mm/min con G94, mm/vuelta con G95 (en torno suele ser el modo por defecto)

Frequently Asked Questions (FAQ)

What does G06.2 mean in a CNC program?

Interpolation of NURBS (Non-Uniform Rational B-Spline) curves directly in the control, reducing block points and improving smoothness. In the catalogue it appears as "NURBS interpolation", within the High speed family.

Can you give me an example of G06.2?

G06.2 P... K... X... Y... Z... F... — Interpolation of NURBS (Non-Uniform Rational B-Spline) curves directly in the control, reducing block points and improving smoothness.

Which machines use G06.2?

G06.2 is used in: Milling, Mill-turn.

What should you watch out for with G06.2?

Medium risk: it rarely breaks anything on its own, but a wrong value shows up on the part. Check the block before running the batch.
