- 108 -
(iv) A and both X and Z are inputted
-> The end point of the arc and line will be determined.
The tangential point selection request window is not
displayed.
(4) ARC
(a) When the preceding figure block is not pending, and TANGNT
is not specified
(i) I and K are inputted
-> This arc will be pending.
(ii) X, Z and R are inputted, or
(iii) X, Z, I and K are inputted
-> A minor arc will be determined.
NOTE
In the distance (radius) between the start point and
center differs from the one between the end point
and center, the figure displayed in a graphic
window will differ from the actual form, and
machining will not be performed correctly.
(iv) Only R is inputted
-> By specifying TANGNT and inputting a line with A =
180 degree and X coordinate as an immediately after
figure, this arc can be determined.
However, there are two possible tangential points, so
one of them must be selected by inputting number data
1 or 2.
