TOMATECH AUTOMATION
� R is valid and I, K are invalid when they are input at the same time.
� R value must be equal to or more than half distance from starting point to end point, and
The system alarms if the end point is not on the arc defined by R command;
� Omit all or one of X(U), Z(W); coordinates of starting point and end point of this axis are
the same when omitting ones, the path is a full circle(360°) in G02/G03 when center
point are specified by I,K; the path is 0(0°) when center point is specified by R.
� R should be used for programming. The system executes in R= I 2 + K 2 to ensure
Starting point and end point of arc path are the specified ones in I, K programming.
� When the distance from center point to end point is not equal to R(R＝ I 2 + K 2 ) in I,K
programming, the system automatically adjusts position of center point to ensure
starting point and end point of arc path are the specified ones; when the distance from
center point to end point is more than 2R, and the system alarms.
� Arc is less than 360° when R is commanded, the arc is more than 180° when R is
negative, and it is less than or equal to 180° when R is positive.
Example: Arc cutting path from Φ45.25 to Φ63.06 shown in Fig. 3-8.
