Re: CAD Drawings?

When we started out 3 years ago our machine was very basic. We machined some stuff, but mostly it utilized parts 'as-is' from the legal materials sources. I realized, after going to the finals, that if we were going to run with the big dogs, we needed better equipment. I've used Autocad & Microstation for years as an Electrical Engineer but I had not drawn much in the mechanical arena. I had all summer to practice. Last year, I needed to design a gearbox to rotate our basket and utilized cad to generate a model, production drawings, and gear profiles that we downloaded into our Wire EDM. There is no way I could have pulled this off without CAD. We also figured out a better way to hold the drill motor/transmission assembly (I can't stand those rinky-dink drill housings)using CAD and downloaded this design to a CNC mill that knocked 'em right out. The more I worked with CAD on this project, the more I relized the potential to build better machines. I even went as far as to measure everyone's parts and build a model of that machine. It was cool but not that useful after the fact. It did, however, impress the students and cranked me up for this year. Now I'm CAD crazy. This year I designed and manufactured retractable 'landing gear' wheels on Autocad. You've got to see them. Once again I used the data to tell our CNC shop equipment what to do (I cut all of the sprockets with a laser). I modeled most of the components in the 'kit-of parts' and then went back and did last years. Best of all, I have a model of this years machine that has helped us check for assembly problems. I've got a lot of data that I would love to share with the rest of you guys. I've always felt that a parts database would be a great thing have on-line but I don't have the resources to start one. If anyone can get one started, I'll send models. I get laughed at a little and I don't get much sleep but it pays off in the end by inspiring the students as to what Engineering is and after all, that's what it's all about....... Come see us @ Pit #34 Ed |
