Post Processor Dialog

The Post Processor button in the Top Level palette becomes active once machining operations have been created in a file. Clicking on the Post Processor button will display the Post Processor dialog shown below. This dialog allows the user to select a post processor, specify a program name and format the output.

The Process button will generate the NC program for the file currently open. The text file will be saved under the file name displayed to the right of the Program Name button. If a file with that name already exists, clicking the Process button will erase the old file and replace it with the new one. To view the text file as it processes, click on the Text Window button. When this button is depressed, a window will appear that displays the posted text file as it is created. The program will scroll by in the window as it is being generated. The Pause button allows the user to stop the scrolling of the output as it is being processed. The Print button will be available after the program file is finished processing.

Before posted output can be generated, the post processor and program file name must be specified. When a file is post processed, a text file is created with the extension specified in the Post text box in the File Extension dialog. By default, this extension is set to .NCF. A file can be post processed multiple times and saved with different .NCF file names. If changes are made to the part file, it must be post processed again in order to incorporate the changes into the posted output. As a default, the text file uses the part file name with an .NCF extension (e.g. EXAMPLE1.NCF). This file name can be changed by clicking on the Program Name button and entering a new name.

To specify an output file name for the finished program, click on the Program Name button. The system will automatically add the extension specified in the File Extension dialog. Selecting File Extension from the Preferences submenu in the File menu will display the File Extension dialog shown above.

To select the post processor, click the Post Selection button. An Open dialog will appear that allows the user to access the directory or folder where the post processors are stored in the system.

The actual file names of the post processors are different depending on the operating system. However, when selecting a post processor, the full name (including the Control and Machine) will be displayed in the Open dialog.

Posted Output Format

The items in the top box of the Post Processor dialog change the format and contents of the finished output. Each item can react differently with different post processors. Below is a description of the effect they will have with most post processors.

Selected Ops

Checking this item will cause the output to only include operations that are currently selected in the Operations list. Items that are unselected will not be output.

Starting Program Number

This is the number of the program as it will appear in the control. It is also the starting number for all sub-programs. If the Starting Program Number is one, the first sub-program will be two, the second three, etc.

Sequence from

This is the starting number for the block numbers or "N" numbers. The by box determines the increment.


If this option is turned on, the post processor will only output block numbers on tool change positions.

Insert Comments

This option will output information about each operation and tool used as well as file length. If any additional comments have been entered by the user about tools or operations, they will be output as well.

Insert Optional Stops at Tool Change Positions

If this option is on, the software will output a machine operator selectable program stop at every tool change.

Post Output Preferences

The Post Processing preference allows the user to specify comment data that is output in the NCF file generated by the system. If an item is checked, that data will be output. This dialog can be found in the File menu under Preferences
