15.1.17 Splines (Akima)
This type of machining adapts the programmed contour to a spline
type curve that goes through all the programmed points.
The contour to be splined is defined with straight paths (G00/G01).
When defining an arc (G02/G03), the spline is interrupted while
machining it and it resumes on the next straight path. The transitions
between the arc and the spline is done tangentially.
#SPLINE ON Activate spline adaptation.
When executing this instruction, the CNC interprets that the points
programmed next are part of the spline and begins making the curve.
The programming format is:
#SPLINE ON
The machining of splines cannot be activated if tool radius
compensation (G41/G42) with linear transition between blocks
(G136) or viceversa.
#SPLINE OFF Cancel spline adaptation.
When executing this instruction, the CNC ends the spline and goes
on machining as the path were programmed.
The programming format is:
#SPLINE OFF
The spline can only be canceled if at least 3 points have been
programmed. When defining the initial and final tangents of the spline,
2 points will be enough.
The dashed line shows the programmed profile.
The solid line shows the spline.
