Mechanical

I have developed a variety of mechanical drafting and design plans over the years. Below are a sample of some of the various mechanical jobs I’ve been involved with in the past…

Hydraulic Motion-base Assembly
Modeled completely in AutoCAD, this complex assembly involved importing various 3D models from vendors supplying bearings, pistons, etc. Interfacing with the product it was intended to move around was also a consideration. Location of all mechanical components to aid both maintenance and packaging constraints, and range of motion limits were also an issue.

Plastic Molding Design
Here is an example of a 3D solid modeling job I did using Autodesk Inventor. The client needed a number of plastic parts designed and sent to mold makers for bidding. The client needed parts designed in 3D to provide a visualization of the part and also to be able to export IGES or SAT file formats so mold makers would be able to import them into their CAM systems to build the mold. Also, some mold making companies (like ProtoMold) allow you to upload IGES or SAT files to their website directly for a fast turnaround.

Automotive Weatherstriping Design
This was a rather complex project involving a International Harvester jeep mechanic and manufacturer that wanted to attempt to re-manufacture the weatherstripping around the triangle windows found on the side doors of these aging jeeps. Their shape was quite complex and required extensive measurements of prime samples to create this detailed drawing for mold makers to inspect. Although I could have created the design in 3D using Autodesk Inventor and then created SAT or IGES files for the mold maker, the client opted for a simple 2D plan with plenty of measurements. The mold required inserting metal stiffeners at specific points as well. Believe me, after fully measuring out this part, I now understand why no one has attempted to re-manufacture this part yet!!
