Blocks 13 to 24:
Corresponding to blocks 1 to 12
from program 360074
Blocks 1 to 12:
Assign numerical values to the Q
parameters
Example for exercise: Full circle
Circle center CC: X = 50 mm
Y = 50 mm
Beginning and end
of circular arc C:
X = 50 mm
Y = 0 mm
Milling depth: Z = –5 mm
Tool radius: R = 15 mm
