Post Block Reference : General Post Blocks
Introduction
In this topic we will cover each of the default post blocks in the Mill post processor. The purpose and use of each block will be explained. It is important to know that the description or name of the block may differ from post processor to post processor as the name (the text to the right of the post block number) is not used by the post processor engine, and is simply a reference to aid in understanding the purpose of the block.
The post blocks are organized by numeric sequence. This post blocks themselves may or may not be in numeric sequence in a post processor
General Post Blocks
Block 7. Sub Program Call
This postblock is used to format the output into the NC program that is calling a sub program to be run in the program.
Example: "N51 M98 P10 (SUBPROGRAM CALL)"
NOTE: sub programs will only be output if the sub program option is enabled inside the Machine Definition > Posting page.
Block 8. Sub Definition
This postblock is used to format the beginning of the sub program itself that is output into the NC program.
Example:
O10 (SUBPROGRAM OF O100)
G91
N01 G01 Y0.5
N06 G02 X0.765 Y0.765 I0.765
NOTE: that sub programs will only be output if the sub program option is enabled inside the Machine Definition > Posting page.

Block 10. Primary Rotary Axis Index String
Rotary output is broken into two categories, Indexing, and simultaneous. This block is called when the command variable "output_primary_rotary_index" is encountered by the posting engine on a post line. The purpose of this block is to handle the output of the rotary index position into the NC file. Indexing moves are typically not executed along with XYZ position moves, but rather on their own line of code.
Command variable used to call block 10 in a postline:
Variables used in this block to access rotary position:
Block 11. Cancel Cutter Compensation

This post block is used to output the necessary commands to put a machine in rigid tapping mode. This usually puts the machine into a feed per revolution mode. When the rigid_tapping_start variable is encountered on a post line by the posting engine, the system will call block 22 to output the rigid tapping startup commands. The posting engine will only use the rigid tapping blocks when post question 272 is set to "y". The post question 233. also needs to be set to "y" to allow the posting engine to output the tapping motion as a canned cycle.
Post blocks and post questions associated with block 22:

This block is currently not in use and should be removed from all current *BCPst post processors.
Block 26. Set Debug Comments For Post Editing
This block contains a special command variable used by the posting engine to signal that debugging comments should be output into the NC file. The debugging comments aid in tracking down what postblock is outputting code on the various NC file lines.
The command variables used in block 26 to turn on/off debugging is:
When debug_on is present in this block, the posting engine will output the debugging comments.
When debug_off is present in the block, the posting engine will not output the debugging comments.

Block 28. Rapid Move (Deprecated)
This block is currently not in use and should be removed from all current *.BCPst post processors.
Block 30 and Block 31. Initial Positioning code for operation not on transform plane
The BobCAD-CAM posting engine includes support for using Transform Plane/Coordinate Rotation functions on the CNC controller. When cutting 3+2/Indexing operations some machines have a function that allows them to rotate the coordinate system on the machine tool itself. The advantage of this is the ease of understanding the coordinate values used in the program by the machine operator, and also the ability to use tool offsets and canned cycles for operations like drilling when on a rotated plane or face.
In the BobCAD-CAM software there are several options that when enabled will make the posting engine call Block 31 to allow the formatting of the coordinate rotation command as well as then outputting all of the position coordinate relative to this new plane while the Coordinate Rotation function is enabled.
Options used to enable Transform Plane Output
Machine Definition > Posting
On each Index system when they are created the user must enable the Use Transform Plane option. Additionally there is an option to allow "Use Index System Origin" When this option is active, the posting engine will output all coordinates relative to the origin of the index system. It is up to the post writer to make sure the definition of the transform plane (in block 31) includes the proper formatting to not only rotate the coordinate system, but also translate the zero to the new location.
See the Transform Plane section of the Post Variable and API document in the BobCAD-CAM help system for more details on the available variables.
Block 32. and Block 33. End code for operations on or not on a transform plane.
This postblock is called when the command variable "initial_positioning" is encountered on a postline.

Wrapping groups are used to create machining operations that substitute a linear axis for a rotation axis. Also referred to as Axis Substitution.
Block 193. Canned Cycle Drill Point Format for Bore #3 Canned Cycle When Wrapping (No Subprograms)
This block is used to format and output the subsequent drill point locations for Bore #3 canned cycle operations that exist under a wrapping group in the CAM tree. Wrapping groups are used to create machining operations that substitute a linear axis for a rotation axis. Also referred to as Axis Substitution.
Block 194. Canned Cycle Drill Point Format for Bore #1 Canned Cycle When Wrapping With Dwell (No Subprograms)
This block is used to format and output the subsequent drill point locations for Bore #1 canned cycle operations that exist under a wrapping group in the CAM tree with a dwell value entered on the tool page of the operation. Wrapping groups are used to create machining operations that substitute a linear axis for a rotation axis. Also referred to as Axis Substitution.
Block 195. Canned Cycle Drill Point Format for Bore #2 Canned Cycle When Wrapping With Dwell (No Subprograms)
This block is used to format and output the subsequent drill point locations for Bore #2 canned cycle operations that exist under a wrapping group in the CAM tree with a dwell value entered on the tool page of the operation. Wrapping groups are used to create machining operations that substitute a linear axis for a rotation axis. Also referred to as Axis Substitution.
Block 197. End of Operation - Toolchange
This block is called at the end of every machining operation where the next operation uses a different tool number. This means the machine will be performing a tool change operation and the codes in this block should finish the current operation and move the tool/spindle to a safe location so the next operation can change the tool.
Block 198. End of Operation - No Toolchange
This block is called at the end of every machining operation where the next operation uses the same tool.
Block 199. End of Last Operation
This block is called at the end of the last operation in the program. The block is commonly used to end the current tool in such a way to prepare for the end of the NC program itself. Note that post block 5 will be called after this block to end the NC program.
