Programming example
N10 R1=30 R2=32 R3=10 R4=11 R5=50 R6=20 ;Assignment of initial values
N20 MA1: G0 Z=R2*COS (R1)+R5
X=R2*SIN(R1)+R6
;Calculation and assignment to axis
addresses
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
parameters. The calculation of the coordinates in X and Z and the processing takes place in
N20.
In block N30, R1 is incremented by the clearance angle R3, and R4 is decremented by 1.
If R4 > 0, N20 is executed again; otherwise, N50 with End of program.
