3.7 Parabola Interpolation G7.2, G7.3
Command format: G7.2
X(U)__ Z(W)__ P__ Q__
G7.3
Command function: G7.2 motion path is the CW (rear tool post coordinates)/CCW(front tool
post coordinates) parabola.
G7.3 motion path is the CCW (rear tool post coordinates)/CW(front tool
post coordinates) parabola.
Command path:
G7.2 path sketch map G7.3 path sketch map
Explanation:
G7.2, G7.3 are modal;
P is in the parabola standard equation Y
2
=2PX, its range: 1 ～ 9999999(unit:
0.001mm, without sign);
Q is the angle between the symmetrical axis of parabola and Z, and its range: 0 ～
99999999 (unit: 0.001°) .
Parabola direction: G7.2/7.3 interpolation directions in the front tool post coordinate system and
the rear are reverse.
