Creating or configuring a new post processor in involves setting up machine-specific logic to translate neutral toolpath data into NC code. For the latest versions (2024/2025), the process is increasingly handled through the Configuration Center
, which centralizes settings for the machine and controller. 1. Preparation and File Structure Locate Existing Posts
: The easiest way to start is by modifying an existing post processor that matches your controller (e.g., Fanuc, Heidenhain, or Siemens). Identify Core Files : Post processors typically consist of two main file types:
: Contains the main logic for handling operations, cycles, and movements.
: Contains definitions for variables, macros, formats, and machine parameters. Default Directories : Standard files are often stored in C:\Users\Public\Documents\OPEN MIND\mdf 2. Configuration Steps Open Configuration Center
: Use this utility to manage the setup wizard and system checks for new machines. Define Machine Kinematics
: Specify the machine type (3-axis, 5-axis, etc.) and axis configurations. For complex 5-axis machines, you may need to use the to handle collision-free orientation and axis swapping. Customize NC Output : Edit the files using a text editor (like Cimco Edit ) to adjust: Formatting : Floating point vs. integer positions. Start/End Commands
: Add specific M-codes or G-codes required for your machine's startup and shutdown sequences.
: Map hyperMILL drilling or milling strategies to specific controller cycles (e.g., Heidenhain TNC cycles). OPEN MIND Technologies 3. Implementation and Verification Restart Software
: After adding or modifying files, restart hyperMILL to see the new post processor in the available options list. Virtual Machining : In the latest versions, use hyperMILL VIRTUAL Machining
to simulate the NC code against a virtual model of the machine and PLC to ensure safety before running on the physical machine. : Always keep a backup of the original files before making manual edits. Key Benefits of Tailor-Made Posts Postprocessors | CAM software - OPEN MIND Technologies
The role of a post processor in hyperMILL is to act as the essential bridge between digital CAM programming and physical CNC execution. In modern manufacturing environments, particularly with the introduction of hyperMILL VIRTUAL Machining, the post processor has evolved from a simple code translator into a sophisticated link that ensures safety, efficiency, and real-world accuracy. The Core Function: Neutral Data to Machine Code hypermill post processor new
At its most basic level, hyperMILL calculates toolpaths as "neutral data" (POF format), which are independent of any specific machine or controller. The post processor takes this neutral information and converts it into specific G-code or M-code tailored to a particular machine-controller combination, such as Heidenhain, Siemens, or Fanuc.
A well-optimized hyperMILL post processor does more than just translate; it exploits the unique "intelligence" of the controller, such as:
Control Cycles: Utilizing built-in canned cycles for drilling or tapping.
Path Correction: Handling tool radius compensation effectively.
Complex Kinematics: Managing RTCP (Rotation Tool Center Point) and TCPM for 5-axis simultaneous machining. Advancement: hyperMILL VIRTUAL Machining
The "new" paradigm in hyperMILL post processing revolves around VIRTUAL Machining. Unlike traditional post processing, where code is generated and then separately simulated, this technology creates a bidirectional connection between the CAM system and the machine.
VIRTUAL Machining Optimizer: This component automatically selects the best solution for complex movements, avoiding axis limitations and generating optimized connection paths to reduce auxiliary processing time.
Connected Machining: This allows hyperMILL to read out actual machine parameters and compare them with the NC code requirements. It ensures that the virtual programming environment perfectly matches the real-world setup, significantly reducing the risk of collisions.
Real-Time Synchronization: Simulation is synchronized with actual machine movements, providing a high level of security for expensive 5-axis machinery. Customization and Implementation
Every manufacturing task is unique, and Open Mind Technologies emphasizes tailor-made post processors. While standard post processors are available, high-end shops often require customization to match specific workflows or specialized machine features like serrated or grooved rotary axes.
Users can manage these through the hyperPOST interface. The configuration is typically stored in .omf files, which define how the post processor formats the final output. To implement a new post processor: Postprocessors | CAM software - Open Mind Technologies Creating or configuring a new post processor in
In hyperMILL, the post-processor acts as the critical bridge that converts neutral toolpath data (POF format) into machine-specific NC code. Modern versions of hyperMILL emphasize a "new generation" of post-processors integrated with Virtual Machining technology, which ensures that the generated code is not only compatible but also optimized for the specific machine's kinematics and control cycles. 1. Core Concept & Functionality
Neutral Data Output: hyperMILL first calculates machine-independent toolpaths (POF format).
Customization: Post-processors are specifically matched to the machine tool and controller (e.g., Heidenhain, Siemens, Fanuc) to exploit advanced features like control cycles and path correction.
One for All: A single post-processor can often handle both milling and turning operations within a combined mill-turn environment. 2. The "New" Standard: Virtual Machining
The latest approach moves beyond simple code conversion to NC code-based simulation:
Optimizer: This module automatically selects the best tool orientation and avoids collisions based on the machine's actual limits.
Connected Machining: This allows for a bi-directional link between the CAM station and the machine tool, ensuring the post-processor uses the exact real-world setup data. 3. Working with Post-Processors (How-To)

hyperMILL 2025 , the post-processor has evolved into a key component of the VIRTUAL Machining
suite, moving beyond a simple G-code translator to a "digital twin" that actively optimizes toolpaths during generation. OPEN MIND Technologies Key New Features & Enhancements Virtual Machine (VM) for Calculation : A major update allows hyperMILL to use the machine model directly during toolpath calculation rather than just during post-processing. This enables: In-Calculation Collision Avoidance
: The software considers the specific machine geometry and limits (e.g., machine head proximity) to create safer paths in tight spaces. Smooth Overlap New features and updates : The latest version
: Areas where the machine limits might have caused a stop are handled with "smooth overlap" to ensure no visible transitions. Enhanced NC Optimizer Axis Swapping
: For machines with limited linear axis ranges, the Optimizer can now transform X and Y movements into rotations (e.g., CX movement) to avoid "rewind" movements. Closest C-Axis Angle
: A new "Closest C-angle" option helps minimize large rotations, improving machining accuracy and reducing programming time. Dynamic Stock Integration : Linking movements are now optimized for actual stock conditions
in real-time. The post-processor uses an automatically updated stock model to ensure rapid movements are safe and efficient. Turning & Multi-Spindle Support
: Enhancements specifically target post-processors for Siemens, Fanuc, and Mitsubishi (Mazak) controls, particularly for main and sub-spindle applications. Virtual Tool (VT) Connectivity : You can now define rules for machine-specific adapters
(like HSK63 vs. SK50) directly in the post-processor. This allows automation macros to automatically swap tool couplings when you change your post-processor to a different machine. P and C Tool | Mold Die | CAD CAM software | OPEN MIND

Some potential applications of HyperMill include:
Old posts often lack "Machine Lock" functions for specific axes or fail to output proper subprogram calls for pallet changers. A new post from OPEN MIND or an authorized partner is pre-configured with safety logic.
HyperMILL looks for posts via environment variables.
HYPERMILL_POST_DIR.D:\HyperMILL_Posts\New_Machine_2025).When deploying a new HYPERMILL post, the best shops use a strategy called Machine Mirroring.
Before cutting metal, engineers run the new post through a digital twin of the machine (e.g., Vericut or CELOS). The new post should generate code that, when simulated, matches the HYPERMILL stock removal exactly. If the post is configured correctly, you should be able to run the program on Monday morning without dry-running the first tool.
