X100 ,A30 (this specification is
equivalent to X100 Y57.735
where 7.735=100Atg30°)
Y100 ,A120 (this specification is
equivalent to X-57.735 Y100
where !57.735=100/tg120°)
X-100 ,A210 (this specification is
equivalent to X-100 Y-57.735
where !57.735=!100Atg30°)
Y-100 ,A300 (this specification is
equivalent to X57.735 Y-100
where 57.735=!100/tg120°)
L Note:
– Straight line with angle together with chamfer or corner rounding can be defined in one block. For
example:
X100 ,A30 ,C5
Y100 ,A120 ,R10
X-100 ,A210
– Angle specification at address ,A can also be applied in drilling cycles. In this case it is
acknowledged in the course of positioning execution in the selected plane.
For example block
G81 G91 X100 ,A30 R-2 Z-25
is equivalent to the block below:
G81 G91 X100 Y57.735 R-2 Z-25
