The address of the tool angular axis angle can be output using the
following NC machine file setting and function code.

Function Remarks
2 1 0 3 Outputs the tool angular axis angle (Bb) Address set in MTF1405
(NC machine file: Address output format)
No. Format Initial value Description
1405 2 characters BB Address of the tool angular axis angle
The tool slant angle to be output is determined as follows:
1) Milling of slanted surfaces
The tool slant angle is determined automatically from the slant angle
of the machine figure.
Tool slant angle = machine figure slant angle
2) When the tool axis of the milling tool is tilted
The tool slant angle is determined according to the tool setting
direction as follows:
SETTING DIRECTION CP = 0 (for side facing) !
R tool slant angle = 0
SETTING DIRECTION CP = 1 (for front end facing) !
R tool slant angle = 90
SETTING DIRECTION CP = 2 (for rear end facing) !
R tool slant angle = –90
3) When the tool axis of the turning tool is tilted
The tool slant angle is determined according to the tool setting angle
as follows:
SETTING ANGLE AS = –90 ! R tool slant angle = 0
SETTING ANGLE AS = 180 ! R tool slant angle = 90
SETTING ANGLE AS = 0 ! R tool slant angle = –90
The tool angular axis indexing angle can be output with an arbitrary sign,
using an arbitrary position as the origin, by setting the following MTF.
(In figure definition, however, the slanted surface angle is always entered
with reference to the Z–axis.)
No. Format Initial value Description
1087 Bit 00000100 Bit 1 Sign of the tool angular axis angle
0: specifies to output the sign of the tool angular axis angle without
inverting it.
1: specifies to output the sign of the tool angular axis angle by inverting it.
1125 Real number 0 This set value is added to the tool angular axis angle.
