Angle and segment length
In this type of programming the angle and the magnitude (segment length) are always quoted, similarly to polar co-ordinates.
Parameter | Description |
|---|---|
ANG | Angle in degrees with reference to the abscissa ( -360 ≤ ang ≤ 360 ) |
SEG | Magnitude of the segment length |
Sample 1:
N10 G01 ANG=45 SEG=424.264 F60000
N20 G01 ANG=0 SEG=400
N30 G01 ANG=-45 SEG=282.843
or
N10 G01 ANG=45 SEG=424.264 F60000
N20 G01 X700 Y300
N30 G01 ANG=-45 SEG=282.843
Restrictions:
- The programming may only be done in the chosen principal plane.
- The length of the segment must be greater than zero, and refers to the projection in the principal plane.
 | It is additionally possible to program rounding or chamfering. The ANG and SEG parameters must be programmed in every block. The assignment may use R parameters, but formulas cannot be programmed. |
Angle and one component in the plane
As above, an angle is programmed, but the length of the segment is no longer specified directly. It is calculated from a component in the selected principal plane.
Sample 2:
N10 G01 ANG=45 X300
N20 G01 ANG=0 Z700
R10=100
N30 G01 ANG=315
X=R10
| Runtime error If either two components in the plane are quoted or none at all, the result is a run-time error. A run-time error is also generated if the movement is parallel to the abscissa or to the ordinate, and there is therefore no intersection. |
