The character of the tool length compensation number used in the AI HPCC / AI
NANO HPCC mode is displayed in reverse as the following figure.
ctual tool length compensation number
2.12.3 Target Axis
The Z axis is the target of the tool length compensation. But it is possible to
change the target axis by the parameter No.5001. Please refer to FANUC Series
16i-MB OPERATORS MANUAL B-63534EN for detail.
2.12.4 Tool Geometry and Wear Offset
When the option of the tool geometry and wear offset is effective, an actual offset
amount becomes the summation of the geometry and wear offset amount
commanded by H number.
A different offset number cannot be specified in geometry and wear.
2.12.5 Instruction Form
When you use G43/G44 and G49, G43/G44 and G49 must be nested between G05
P10000 and G05 P0.
2.12.6 Tool Length Compensation by Coordinate System Shift
There are two types of Tool length compensation by axis movement and by
coordinates shift. Which type of Tool length compensation is used by parameter
(No.5006#6 TOS) setting.
2.12.7 Warning
Warning
When CNC is reset in tool length compensation mode, the mode becomes tool length
compensation cancel (G49) and tool length compensation vector is cleared, not depend
on parameter No.3402#6(CLR).
When the first time automatic operation (MEM or MDI mode) is executed after resetting
CNC, the axis moves to negate the cleared vector (the canceling of tool length
compensation is executed). Therefore, please take enough clearance before automatic
operation to prevent tool from interfering with workpiece.
