Meaning
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
Meaning
Fast non-smoothed path acceleration
Soft smoothed path acceleration
Velocity-dependent path acceleration
Meaning
2½D TRC
2½D TRC relative to the current frame (inclined plane)
3D TRC for circumferential milling
3D TRC for face milling with change in orientation
3D TRC for face milling with constant orientation. The
tool orientation is defined by G17 - G19 and is not
influenced by frames.
3D TRC for face milling with constant orientation. The
tool orientation is the direction defined by G17 - G19
and, in some cases, rotated by a frame.
3D TRC for circumferential milling taking into account
a limitation surface with 3D radius compensation: Con‐
tour on the machining surface
3D TRC for circumferential milling taking into account
a limitation surface with a differential tool on the tool
center-point path: Infeed to the limitation surface
2½ D TRC in relation to the differential tool
2½D TRC in relation to a differential tool relative to the
current frame (inclined plane)
