LNote:

– 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
