Programming
12. When the system is executing the feed hold or single block, the program pauses after
the system has executed end point of current path;
13. d

commands;
14. There are no the same block number in ns~nf when compound cycle commands are
executed repetitively in one program;
15. The tool retraction point should be high or low as possible to avoid crashing the
workpiece.
Cutter radius compensation:
When the cutter radius compensation should be used in the compound cycle code (G70,
G71, G72 or G73), the G41/G42 code should be specified at the 1
st
block (ns block) of the
finish-turning path; otherwise, the cutter compensation will not be used in the compound cycle; it
is not necessary to specify the G40 in the finish-turning path. The cutter radius compensation will
authomatically cancel when the compound cycle is completed. Actually, when the cutter radius
compensation is used in the compound cycle code, the CNC system is performed the cutter nose
radius offset for the finish-turning path instead of entering the state of the cutter radius
compensation. Therefore, the cutter radius compensation state on the position interface will not
change.
The cutter radius compensation genterates before entering the compound cycle, temporarily
cancel the cutter radius compensation; restore the cutter radius compensation when the cycle
end tool leaves from the cycle start; refer to the following schematic:
Fig. 3-70
When the compound the cycle is performed in the rough machining, perform the infeed
along with the cycle start and 1
st
point offset vector point of the finish-turing path, and its feed
value is d; refer to the following figure: △
