TOMATECH AUTOMATION
I: X difference value between circle center and starting point of arc in radius;
K: Z difference value between circle center and starting point of arc;
Center point of arc is specified by address I, K which separately corresponds to X, Z, I, K
expresses the vector (it is the increment value) from starting point to center point of arc as
the
following figure;
I=Coordinates of center point-that of starting point in X direction; K= Coordinates of center
point-that of starting point in Z direction;
I, K are with sign symbol. When directions of I, K are the same as those of X, Z, they are
positive,
otherwise, they are negative.
X, U, Z, W, R, I, K range is referred to Table 1-2 of Section 1.4.1, unit: mm/inch.
Arc direction: G02/G03 direction (clockwise/counterclockwise) is opposite on the front tool
post coordinate system and the rear one as Fig.3-7:
Notes:
� When I = 0 or K = 0, they can be omitted; one of I, K or R must be input, otherwise the
system alarms.
