Front tool post coordinate system Rear tool post coordinate system
Q value:
it is a motion angle from the Y positive direction overlooking XZ plane when the tool
CW rotating in the positive direction to the long axis of the parabola in the right hand rectangular
Cartesian coordinate system as follows:
Front tool post coordinate system Rear tool post coordinate system
Notes:
z P cannot be 0 or omitted, otherwise the system alarms;
z P has no sign. If it has the negative sign, its absolute value is executed;
z Q can be omitted, at the time, the symmetrical axis of the parabola is parallel with or coincident
with Z ;
z The system alarms when the straight line on which the starting point and the end point is parallel
with the symmetrical axis of the parabola;
z
G7.2, G7.3 can be used to the compound cycle G70
～
G73, and their notes are the same those
of G02, G03;
z G7.2, G7.3 are used to C tool compensation, and their notes are the same those of G02, G03;
Example: when the parabola P=100(the least increment is 0.0001mm), its symmetrical axis is
parallel with Z. Its machining sketch map and programming are as follows:
