Thanks Clamboni. We should collaborate, I’ll send my technical posts over and you can translate them for TU!
Bruce. Nature is one big science lab. Art is fooling natures creation with my own.
Kyle. Welcome to TU. Wow, a fellow tube jockey! Just about everything that I model, goes over to you guys to generate the production tools. You are the guys that tell me, “you cannot do this, you cannot do that, the radius is too small, the pocket is too deep etc”. I would locate a smiley face here, to show that I am only joking, but smilies are not for me.
There are two subjects within the title ‘mathematical modeling’. One is CFD’s (computational fluid dynamics),which is a software that will take a computer design and apply flow to it and determine the result. CFD’s are still relatively in their infancy, but the day will come (very soon) when you will see your lure design idea swimming on your screen, long before you get your tools out. With CNC machines (computer numeric control), you might not even have to do that. Hell, you can even get a robotic arm to paint it. The second definition of mathematical modeling is what we do, basically, drawing in 3D.
Yes, we can manually carve and test prototypes. When we have something that works, we can collect the point data with some kind of digitizer and make a 3D model. This in turn is sent to DelW, who will send me an aluminium mould the very next day! These point digitizers are not even beyond the average designer. I have seen them advertised as optional extras on small CNC milling machines.
I’m not sure how the big boys operate. But I would imagine that at the very beginning of a project, some hand carving would take place. They may well go straight in with a computer model and rough a few out on the CNC. If I owned a CNC, I would not be doing any more hand carving. I would CNC a block of wood, make an RTV (rubber) splash and cast a foamy (expanded polyurethane foam) for testing.
From a CAD (computer aided design) designer point of view, working with point data on such a fiddly little subject would be a real pain, I would sooner model it from scratch, taking a few measurements and eyeball it. Catia V5 is a wonderful tool. The generative surface design is a dream come true. If you construct the models correctly, you can make a change to one of the first surfaces and everything drawn after that will be automatically changed. In other words, I can draw a basic lure shape, surface it up, add the lip, eyes, hooks, everything. I can then go back to the original sketch of the profile and alter the length, depth, thickness, radii of profile. The finished model will instantaneously re-draw to my new design. AWESOME!!!!
I hope you enjoy TU (tackle addicts anonymous) and come forward with some outlandish theories and innovative designs.
