    Icam UHF Programming Software for Universal Holding Fixture Systems

    Program Universal Holding 
Fixture systems faster, safer and 
with greater confidence using Icam UHF programming technology, now part of Vericut.

    Universal Holding Fixture systems help manufacturers support large, complex and thin-walled parts without creating dedicated fixtures for every component.

    But programming a UHF system can be time-consuming and difficult, especially when hundreds of actuators, vacuum zones, machine movements, and cutting toolpaths need to work together without collision.

    Icam UHF programming software combines CNC post-processing and machine simulation in a single workflow, helping programmers automatically position fixture actuators, avoid collisions and generate production-ready NC code for both the machine and the Universal Holding Fixture system.

    What once required hours or days of manual programming and repeated simulation cycles can often be completed in minutes, depending on machine and process complexity.

    What is a Universal Holding Fixture?

    A Universal Holding Fixture, or UHF system, is a flexible fixturing system designed to support a range of part shapes, sizes, contours, geometries and configurations.

    Instead of building a dedicated hard fixture for every part, manufacturers can use a configurable fixture with multiple actuators, supports or holding points. These actuators can be positioned to support the workpiece during machining, trimming, routing or drilling.

    Universal Holding Fixture systems are especially valuable for large, thin-walled, or low-volume parts, where traditional dedicated fixtures can be expensive to design, build, store, and maintain.

    UHF systems are commonly used in aerospace manufacturing, composite machining and large-part production, where flexibility, repeatability, and efficient 
setup are critical.

    Why UHF programming is challenging.

    Universal Holding Fixture systems are powerful, but they add a new layer 
of programming complexity.

    The CNC machine is no longer the only moving system that needs to be considered. The fixture may also need to move, position, support, retract, 
or activate at the right time during the machining process.

    01.

    Synchronizing hundreds 
of actuator movements.

    02.

    Managing support positions across large parts.

    03.

    Timing vacuum systems and fixture zones.

    04.

    Preventing tool-to-actuator collisions.

    05.

    Coordinating machine motion with fixture motion.

    06.

    Managing indexed and dynamic actuator positioning.

    07.

    Generating setup information for physical fixture elements.

    08.

    Validating the full machine and fixture process before production.

    Without automation, programmers may need to move between CAM software, post-processing, machine simulation, and manual edits many times before the setup is ready.

    This can turn UHF programming into a process that takes hours or days, particularly for large aerospace structures, composite parts, or complex machine and fixture combinations.

    Traditional UHF programming 
vs Icam UHF programming.

    In a traditional workflow, programmers often have to work through multiple disconnected steps. If a collision or positioning problem is found, the process loops back into editing, re-posting, and re-simulating.

    With Icam UHF programming software, post-processing and simulation work together. The software helps automate actuator positioning, simulate the machine and fixture environment, and generate NC code that reflects both the CNC machine, and the UHF system.

    How Icam automates 
UHF programming.

    Icam UHF programming software helps simplify Universal Holding Fixture setup and reduce the time needed to prepare machine-ready programs.

    Step 1.

    Import the machining program

    The process begins with the CAM-generated machining program and the relevant part, machine and fixture information.

    Step 2.

    Automatically position 
UHF actuators

    The software helps determine the actuator positions needed to support the workpiece 
during machining.

    Step 3.

    Simulate machine and 
fixture movement

    The machine, cutting tool, workpiece and fixture actuators can be simulated together to understand how the full process will behave.

    Step 4.

    Identify and avoid collisions

    Potential collisions between the cutting tool, machine components, fixture actuators and supported part can be detected before production.

    Step 5.

    Generate production-ready 
NC code

    Icam technology generates the required NC output for the CNC machine and the Universal Holding Fixture system, reducing manual programming effort and the need for repeated simulation cycles.

    UHF collision avoidance before production.

    Collision avoidance is one of the most important requirements in UHF programming.

    During machining, a cutting tool may approach fixture supports, actuators, vacuum elements, or other holding components. If the fixture position is not correctly programmed, the result may be tool damage, fixture damage, part scrap, machine downtime or a failed prove-out.

    Icam UHF programming software helps reduce this risk by simulating the combined machine and fixture environment before the program reaches the shop floor. This allows programmers to identify actuator interference, tool-to-fixture collisions and other possible issues early in the programming workflow.

    UHF machine simulation 
in a single workflow.

    Icam UHF programming technology integrates machine simulation into post-processing. This is important because UHF programming is not only about where the fixture actuators should be placed. It is about how the complete system behaves during machining.

    Machine simulation can help validate:

    • CNC machine motion.
    • Fixture actuator positions.
    • Tool-to-actuator clearance.
    • Workpiece support conditions.
    • Machine and fixture sequencing.
    • Indexed positioning.
    • Dynamic actuator motion.
    • Vacuum or support timing.
    • Collision risks before production.

     

    By using simulation earlier in the workflow, programmers can reduce the need for repeated trial-and-error cycles and create safer, more reliable CNC programs.
