Command function: when you do not know positions of the circular center of arc and the radius
but coordinates of three points on the arc, you can use G5 to confirm the
arc direction through the middle position between the initial point and end
point.
Command specification: G05 is modal;
I: incremental coordinate value(X) (radius value, direction) of the middle point where
the circular passes corresponding to the starting point, range: ±99999999× least
input increment;
K: incremental coordinate value(Z, direction) of the middle point where the circular
passes corresponding to the starting point, range: ±99999999× least input
increment; as Fig.3-10:
X, U, Z, W, R, I, K range is referred to Table 1-2 of Section 1.4.1, unit: mm/inch.
Fig. 3-10
Notes:
z Middle point: any one point except for the starting point and end point on the arc;
z The system alarms when the three points are in the same line;
z I=0 when it is omitted, K=0 when it is omitted; the system alarm when they are omitted
simultaneously;
z
The meanings of I, K I are similar to their displacement values of the circle center coordinates
corresponding to starting point ones in G02/G03;
z G05 does not execute the whole circle machining;
