2.10 Tool Position Offset
Tool position offset (T code) cannot be commanded in the AI HPCC / AI NANO
HPCC mode. P/S alarm 5000 occurs when this is commanded.
The tool position offset should be canceled before the AI HPCC / AI NANO HPCC
mode is turned on. If not canceled, P/S alarm 5012 occurs.
2.11 Cutter Compensation C
The cutter compensation C can be used in the AI HPCC / AI NANO HPCC mode.
The specifications of the cutter compensation C is similar to that of FANUC
Series 16i-MB excluding a part. Please refer to “FANUC Series 16i-MB
OPERATORS MANUAL B-63534E” for detail. Please refer to ‘2.11.8 Difference
with Series 16i-MB.’ for the difference with FANUC Series 16i-MB.
To use this function, the option of the tool nose radius compensation is necessary.
2.11.1 Format
G codes of the cutter compensation C, which are G40, G41, and G42, are the
same as ones of the tool nose radius compensation.
G05 P10000 ; : Start AI HPCC / AI NANO HPCC
mode
G41(or G42) X__ Z__ D__; : Start Cutter compensation C
…
G40 X__ Z__ ; : End Cutter compensation C
G05 P0 ; : End AI HPCC / AI NANO HPCC
mode
Each code has the following meaning.
G41, G42 : Cutter compensation start
X_ Y_ Z_ : Move command
D_ : Tool offset number
G40 : Cutter compensation end
2.11.2 D Code
Even if the AI HPCC / AI NANO HPCC mode is turned off, D code is kept. The
kept D code is used as a cutter compensation number if not commanding in D
code when the AI HPCC / AI NANO HPCC is turned on again.
