![]() ![]() ![]() VISI is very strong at switching between a solid & surface environment and this allows us to make complex changes where other CAD systems often fall over." Typically, blending can be a very complex task and it is often necessary to explode a model into surfaces and manually apply the CAD modifications. In regards to these particular components and with authority from the original design team, the tooling was modified to remove undercut areas and apply blend radii on sharp edges. To make a part manufacturable, it is vital to interact with the data and make the relevant changes. "Often when models are originally designed, the manufacturing requirements are not always known. "VISI is very tolerant of non-native data", explains Dean Challis. Original CAD model split into core & cavity surface groups using VISI Analysisįor this project, the original CAD model was provided by the customer as a Unigraphics NX file and the part analysis and tool design was performed using VISI Modelling from Vero Software. The volatile nature of fuel prices has forced the aerospace industry to make weight reduction a high priority focus and reducing the weight of aircraft seating significantly reduces aviation fuel consumption and CO2 emissions throughout the operational lifetime of the aircraft, with every kilogram of weight contributing to the running costs of an aircraft to the carrier.ĭeltaCAD Ltd was founded in 2010 by Dean Challis, a design engineer with considerable CADCAM and tool design experience, who provides a comprehensive range of design and manufacturing services from 2D drawings to 3D modelling and CAM programming. JDevon based DeltaCAD Ltd, a start-up company who specialise in CADCAM services has recently collaborated with sub contract tooling manufacturer Casting Support Systems Ltd on a project to provide a leading Aerospace company with aluminium tooling for a carbon composite seat shell for a major civil airline company. ![]()
