8025/8030 CNC PROGRAMMING MANUAL

Let us suppose that the tool’s starting point is X27 Z43 and the X axis is programmed
in radius. The calculation program is P761, shown below:

N20 G76 P00098
N30 P0=K37 P1=K22 P3=K90 P20=K-0.5
N40 P4=F7P3 P5=F8P3 P6=P0F3P4 P7=P1F3P5
N50 G76 G0 G5 XP7 ZP6 (ellipse’s starting point)
N60 P3=P3F1P20 P4=F7P3 P5=F8P3 P8=POF3P4 P9=P1F3P5
N70 P3=P3F1P20 P4=F7P3 P5=F8P3 P10=P0F3P4 P11=P1F3P5
N80 G76 G1 G9 XP11 ZP10 IP9 KP8 F250
N90 P3=P3F1P20 P4=F7P3 P5=F8P3 P10=P0F3P4 P11=P1F3P5
N100 G76 G8 XP11 ZP10
N110 P99=K176
N120 G25 N90.100.P99
N130 G76 G0 X27 Z43
N140 M30

When executing this program in DRY RUN program P00098 is generated and loaded into
the CNC memory for later machining:

N100 G0 G5 X— Z—
N101 G1 G9 X— Z— I— K— F250
N102 G8 X— Z—
N103 G8 X— Z—
N104 “ “ N — “ “
