When you use any tool with the hexagon turret, the offset angle is set as follows:
 When the tool rotary axis's rotation direction is set to CCW, the tool A's offset angle is set to 90 degrees. (Refer to (C) in the
following figure.)
For the R registers (R2634 to R2635), designate the reference tool's offset angle, 30 degrees (30000).
For the R address of the G174/G53.1 command block, designate the offset angle 60 degrees (G176 R60./G53.1 R60.) from
the standard tool.
 The offset angle can be designated using only either the R address in the G174/G53.1 command block or the R register
(R2634 to R2635). In this case, set 0 degree (0) to the one that is not selected.

In the R address of the G174/G53.1 block and R register, specify the tool angle relative to the reference position rotation
angle when the tool axis rotation angle is at 0 degree. Thus, even when the tool axis rotation angle rotates and the tool axis
rotation angle of the target tool is not at 0 degree, make sure to designate the offset angle at which the tool axis rotation angle
is at 0 degree, for the tool axis rotation angel compensation amount.
Rotary axis position automatic-read method ("#1450 5axis_Spec/bit1" is "1")
The tool-side rotary axis position when Simple tool center point control (G174) or tool axis direction control (G53.1) command
is given is treated as the tool axis rotation angle compensation amount.
Direct the tool you use toward the reference position rotation angle (Z(-) of the machine coordinate system) before issuinga
G174/G53.1 command.
(Example) If you use a tool (Tool A) that is at 90 (-270) degrees relative to the reference position rotation angle while "#7933
DIR_T2" is "1" (CCW direction), use the following machining program.
