Historically, GibbsCAM used text-based form files ( .frm ) compiled into binary files ( .pst or .p0d ) using a utility called Comptro. Modification requires defining specific variables, command blocks, and logical switches to alter the G-code output structure. Modern Post Engine (MPE)
For standard vertical machining centers (VMCs) and 2-axis lathes, the post processor is relatively straightforward. It focuses primarily on formatting linear motions ( G01 ), clockwise/counter-clockwise arcs ( G02 / G03 ), spindle commands ( M03 /M04), and basic canned cycles like drilling or tapping ( G81 / G84 ). 4-Axis and 5-Axis Simultaneous Milling
What are you doing? (e.g., 3-axis milling, 5-axis simultaneous, multi-turret lathe)
Once a part program is complete, the user initiates the "post process" function, typically by selecting a post icon from the Top Level Palette. This action opens the "Post Processor" dialog box. Here, the user can select the appropriate pre-built post processor from the library or choose a custom-developed file. After configuring any specific output preferences for the job, the user clicks "Process," and GibbsCAM translates the toolpath data, generating the final NC program file ready to be transferred to the CNC machine.
GibbsCAM categorizes post processors based on machine complexity and kinematic architecture. Choosing the right architecture ensures the software can properly calculate axes movements. Factory Post Processors
If the machine throws an arc radius error, the post processor may be set to absolute arc centers (I, J, K) instead of incremental, or it may lack support for radius (R) formatting.
Advanced posts that manage complex rotary transformations. They handle Tool Center Point Control (TCPC) or Dynamic Work Offset (DWO), allowing the machine to adjust coordinate systems automatically as rotary axes pivot. Key Functions of a Post Processor
Modern machine tools feature advanced capabilities like high-speed machining cycles, dynamic work fixture offsets (G54.2 or G68.2), and canned drilling cycles. A customized post processor unlocks these factory features directly from your GibbsCAM interface. 3. Enhanced Machine Safety
