MachineWorks has been developing best-of-breed CNC simulation and verification software for over 20 years now. Our algorithms provide the engine that powers many well-known CAM applications as well as providing embedded simulation and clash detection for machine tool controllers.
The hard part in simulating machine cutting and milling processes is being able to remove material from stock in real time and as accurately as possible. Only then can clash detection be based on implicit swept volumes rather than time slicing, which is prone to missing clashes. That's why we developed an extremely powerful Boolean engine which can perform material removal with true solid modelling. This combination provides the most effective means to prevent gouges and undercuts.
The DMG Mori / Lasertec 65 Additive Manufacturing machine combines 5-axis milling and laser deposition.
A few years ago, when Additive Manufacturing, or 3D Printing, became more prominent, we decided to repackage the Boolean engine and its associated algorithms such as automatic mesh healing and offsetting. We wanted a more general purpose and simpler SDK that could be applied to many different problems in diverse markets. The result was Polygonica - a fast, robust and easy to use mesh processing SDK which quickly found favour amongst manufacturers developing additive manufacturing software processes.
After all, the subtractive and additive manufacturing processes are not so dissimilar. The former is removing material to make a part, and the latter is adding it. Its the difference between performing successive Boolean subtractions and union operations.
Many CNC manufacturers are now developing hybrid machines that combine the best of both worlds: the complexity of additively manufactured parts with the surface finish and material properties of subtractively manufactured parts.
So it was only natural that we should extend our capabilities to simulate such machines. Our technology can now fully simulate both material addition and removal within a machining process, including defining the true solid model swept volumes for ensuring a rigorous full machine simulation.
At MachineWorks we strive to keep ahead of developments in manufacturing systems. Our SDK products cover the entire range of processes, from 5-axis CNC, Wire EDM, mill-turn to 3D printing (including in full colour).
Of course, it remains to be seen whether Hybrid machining will really revolutionize manufacturing, but when industry heavyweights such as DMG Mori Seiki and Hermle start to get involved, it's worth making sure that the software is poised to take advantage of these exciting new developments.
