Posting
Introduction
The fifth step of the Mill Thread Wizard is to define a few posting
parameters for the feature. This includes the work offset number, and
indexing output. For Mill Turn jobs, the posting mode and submachine settings
also display.

Posting Parameters
Note: The Output Rotary Angle option is only available with
the 4 Axis Standard, 4 Axis Pro, 5 Axis Standard, and 5 Axis Pro modules.
These parameters are used to create indexing programs without using
index systems.
- Output Rotary Angle
Select the check box to have the Rotation Angle output in the posted NC
program.
Clear the check box when not outputting a rotary angle.
- Rotation Angle - type
the rotary angle of the feature for indexing.
Thread Mill Output
-
Line Moves - the toolpath is output as linear segments.
This option is used if the machine controller does not accept helical
arc segments.
-
-
Arc Moves - the
toolpath output includes helical arc segments.

Note: The following settings are available when inside of a Mill Turn job.
Posting Mode
The Posting Mode settings determine how the code is output based on
the type of feature and tool orientation for the operations in the feature
(generally, these settings only display for face milling or cross drilling).
These settings are used together with the Multiaxis Posting settings for
the feature (updating these settings automatically makes certain selections
in the Multiaxis Posting page).
Longhand Code
When selecting this
option, the code is output using the X, Z, and C axes (with Y-axis being
set to zero for the entire operation). This option may be used for machines
that don't support polar interpolation or have a Y-axis.
Tip: The Point
Interpolation settings in the Multiaxis Posting page of the wizard are
important when using the Longhand Code output. Generally, the Interpolation
Type should be set to By Machine Angle.
Auto/Y Axis Mode
When selecting this
option, the code is output using the X, Y, and Z axes (with the C-axis
remaining at a fixed value for the entire operation). The tool uses the
Y-axis travel available instead of rotating the C-axis.
Tip: The Pole
Handling settings in the Multiaxis Posting page of the wizard are important
when using the Auto/Y Axis Mode output. You can set the option to Freeze
Angle Around Pole to use Y-axis motion, and all other options can be used
to not output Y-axis motion.
Polar Interpolation (G112/G12)
When selecting this option, the code is output
using the X, Y, and Z axes, but the machine controller then converts the
values to use the X, Z, and C axes. This option is only used for machine
controllers that support polar interpolation and may provide superior
accuracy and part finishes as the machine controller optimizes the code
for the machine.
Important: Your
machine controller must support and be configured for polar interpolation
to use the Polar Interpolation posting mode properly.

Submachine
The submachine group determines the submachine, or work zone, that is
used to perform all operations in the feature. You can use the Submachine
list to change the submachine for the feature from the default submachine
that is selected in the CAM Tree.
-
Submachine
- displays all submachines (work zones) from the current machine.
The submachines display with the name defined in the submachine definition
of the Current Settings. Select the submachine, such as UT_MS (upper turret, main spindle) to determine which
work zone performs all operations in the feature.
