x actly the same as in examples for Memory Type A:


(TOOL 04 ACTIVE)


G43 Z20 H04


Uses tool length offset 04


(H04)


G01 G41 X500 D34


CNC Plastic plate drilling machine


Uses cutter radius offset 34


(D34)


On some ma chines, the D-offset can not be used, and an H-off set must also be used for the cut ter

Note that the last pro gram ex am ple is iden ti cal to the one be fore (for Type A) What is dif fer ent is the meth ods of in put ting angle machine val ues to the off sets, and that hap pens on the ma chine, dur ing the setup

Tool Offset Memory – Type C


The tool off set Mem ory Type C is the lat est and the most flex i ble of the three Like Mem ory


Type B, it dis tin guishes be tween the Ge om e try Off set and the Wear Off set In ad di tion, it sep a rates the Tool Length Off set and the Cut ter Ra dius Off set, each with its own Ge om e try and Wear off sets


Be cause each automatic punching machine off set has its own reg is try area, the same off set num ber may be used for the H and


the D off sets:

Since Fanuc 0 (FS-0) is the most mod est con punching machine trol in terms of fea tures, there fore not the most
