Significance
Natural transition to next traversing block
Tangential transition to next traversing block
Definition of the last spline section by means of the
last 3 points
Significance
Fast non-smoothed path acceleration
Soft smoothed path acceleration
Velocity-dependent path acceleration
Significance
2½D tool offset determined by G17-G19
2½D tool offset determined by frame
The tool offset is effective in relation to the current
frame (inclined plane).

3D tool offset face milling with non-constant tool
orientation
3D tool offset face milling with constant tool
orientation independent of active frame
3D tool offset face milling with fixed tool orientation
dependent on active frame
3D tool offset circumferential milling with limitation
surfaces
3D tool offset circumferential milling with limitation
surfaces and differential tool
Significance
