Products for UHF

Field Proven Technology

ICAM has been working with customers to provide efficient and innovative ways to simplify UHF set-up programs that have been developed to dynamically move actuators while avoiding collisions.

ICAM’s integrated post-processing & machine simulation solution allows programmers to quickly program various types of UHF systems – what used to take hours or days can now be done in minutes depending on the machining complexity!

What is a UHF System?

A Universal Holding Fixture (UHF) and relative methods corresponds to flexible fixture mechanisms to accommodate a wide range of work-piece contours, geometries, sizes, and configurations. As compared to traditional clamping / holding assemblies that are created for one part and can not be easily used for various different part shapes and dimensions.

Why were UHF Systems Created?

For years organizations were obliged to design and manufacture complex fixtures and tooling in order to properly hold a single free-formed shape. Design, manufacturing, production and storage of these fixture assemblies are very expensive. Currently, companies want to produce small lots of parts on demand and therefore, it is important to find a solution to these expensive fixture systems, especially for large parts like aerospace skin – thus, the birth of UHF Systems.

The Problem

The programming of UHF systems and correct synchronization of the dynamic actuators, to avoid collisions during machining, is very time consuming and dramatically reduces the overall manufacturing process efficiency.

Organizations are spending a significant amount of time to program UHF systems to properly hold the part inside the machine. The height and sequence of each actuator must be programmed and timed in the correct order (between part support, index positioning and vacuum setting). It also requires a proper part list of physical elements to be installed on the machine before initiating the machining process.

Companies that strictly want to use its standard CAM system to compute every single position of the different devices, post-process and simulate the NC program in order to program the UHF correctly, will typically invest several hours to several days of work.

Additionally, programmers will still need to anticipate possible collisions that may occur during machining. Again, the programmer will need to iterate back and forth many times using “after the fact” machine simulation in order to modify the CAM program. This will extend UHF programming time from hours to several days.

The Solution – ICAM’s Integrated Post-processing & Machine Simulation

ICAM Technologies has been working with customers to find efficient and innovative ways to not only simplify the UHF set-up program, but to dynamically move the actuators to avoid any collisions.

ICAM’s integrated post-processing & machine simulation solution allows programmers to quickly and efficiently program various types of UHF systems. What used to take hours or days can now be done in minutes depending on the machining complexity.
