Program example for jumps

Task
Approaching points on a circle section:
Given:
in R5
in R6
20
Fig. 8-33
Programming example
N10 R1=30 R2=32 R3=10 R4=11 R5=50 R6=20
N20 MA1: G0 X=R2
N30 R1=R1+R3 R4= R4–1
N40 IF R4 > 0 GOTOB MA1
N50 M2
Explanation
In block N10, the starting conditions are assigned to the corresponding arithmetic parame-
ters. The calculation of the coordinates in X and Y and the processing takes place in N20.
In block N30, R1 is incremented by the clearance angle R3; R4 is decremented by 1.
If R4 > 0, N20 is reprocessed; otherwise, N50 with end of program.
