Process 3, Akima and B-spline

The interpolation points are programmed by means of G01 or G00 blocks. Programmed G02 and G03 blocks are only possible with Akima Spline type, the transition to these blocks takes place tangentially, and spline generation is temporarily suppressed up to the next G01 or G00 block.

This process is particularly interesting for curves that are completely continuous, or which are continuous in segments, for example circular or elliptical contours approximated by linear blocks.

Select or cancel either by means of G151/G150 or via the string commands
