   Offering both tools and services, Maplesoft Engineering Solutions help engineers validate and optimise product designs, produce extremely fast simulation code for hardware-in-the-loop and other types of simulations where execution speed is critical, and develop specialised analysis and design calculation tools. Maplesoft Engineering Solutions also support model development for model predictive control, an advanced technique used to represent the behaviour of complex systems.  The Maplesoft Engineering Solutions team has expertise in a variety of engineering fields and extensive experience in model-based design. By leveraging the unique benefits of MapleSim and Maple, advanced engineering design tools from Maplesoft, they help engineers reduce development risk, create better products, and get to market faster. MapleSim and Maple are also available for engineers to use directly in their own development projects.  MapleSim is an advanced system-level modelling and simulation tool  that applies modern techniques to dramatically reduce model development time, provide greater insight into system behaviour, and produce fast, high-fidelity simulations. MapleSim is based on Maple, the technical computing software for engineers, mathematicians, and scientists. Maplesoft Engineering Solutions are used by customers in a variety of domains, such as electric and hybrid-electric vehicles, ground transportation, space systems, batteries, mining, and manufacturing. Past projects include a robotic arm for drilling in mines, a motion platform for driving simulators, a torsional vibration analysis tool for marine drivelines, batteries for hybrid-electric vehicles, and dialysis machines. While projects vary greatly, they frequently involve the following: High performance plant models for hardware-in-the-loop (HIL) applications. Generating high-fidelity plant models from many system design tools typically results in code that is not fast enough for real-time, HIL execution, and engineers often perform a trade-off between model fidelity and performance.    

Delcam has launched the 2015 version of its PowerMILL CAM system for high-speed and five-axis machining.  The new release includes improvements to the Vortex high-efficiency area-clearance strategy, improved collision checking to also cover near misses, and more efficient raster finishing.  The Vortex area-clearance strategy produces safe toolpaths with a much deeper cut by using a controlled engagement angle that maintains the optimum cutting conditions for the whole toolpath.  As a result, higher feed rates and material-removal rates are possible, making the cutting time shorter by as much as 70%. In addition, cutting is undertaken at a more consistent volume-removal rate and at a near constant feedrate, so extending tool life and protecting the machine. Two enhancements in PowerMILL 2015 will give even greater reductions in machining time with Vortex compared to conventional roughing. The first change allows toolpaths to approach the part from outside the stock at the cutting height, both for open pockets and in areas where earlier cuts have made this possible. Previously, all entry moves had to be made by plunging onto the surface or by ramping into the material.  The second change allows an increased feed rate to be set for non-cutting moves. The default value is set at double the rate for the cutting moves but this can be altered as required for each machine tool.  The extra time that can be saved depends on the shape of the part but an additional saving of around 20% should be expected above the earlier releases of Vortex. Another problem in previous versions of PowerMILL was that unnecessary lifts could be added to area-clearance toolpaths when the cutter moved outside the stock or close to its edge.  Changes to the roughing algorithm in PowerMILL 2015 have reduced the number of lifts per toolpath slice to the minimum […]
