CEB Press

-THIS IS THE STEP FILE FOR THE CURRENT HOPPER PRESS THAT I HAVE. THIS MAY BE THE SAME STEP FILE AS THE OFFICIAL ONE LISTED ON THE DEV. PAGE.

With Mixer Module

-THIS IS THE STEP FILE THE CURRENT DESIGN FOR THE PRESS WITH THE MIXER MODULE CURRENTLY UNDERGOING TEST.

Design Rationale

  1. The Rotor blade design, which is attached to the shaft in the middle of hopper, and attached to the outer diameter of rotor sweep on the outer edges of hopper - allows for a complete sweep of the hopper - no soil buildup in corners of cylindrical hopper
  2. Anti-symmetric rotor blade design allows for soil sweeping into the middle - as soil from the far ends of the hopper is moved towards the middle.
  3. Reinforcement in middle of rotor blade to strengthen the rather thin blade.
  4. Hopper reinforcement gussets on outside of hopper are not evenly spaced with the outer edges but instead slighly closer to the center of the machine - because outer 'gussets' are 1/2" thick steel, and inner ones are 1/8" thick steel
  5. Simple cylindrical hopper geometry, but needs bending - how?

Do the tines need bending and/or twisting, or are they flat?

CEB2014auger tines.png

Inner gussets towards centerline of machine instead of evenly spaced from edges of hopper because they are thinner (1/8") than edge (1/4"):

-Current FreeCAD Feasibility

I have spent about 20 to 30 hours of the past few weeks in order to test the current capabilities of FreeCAD and also in order to learn the basics of FreeCAD. My impressions are that the FreeCAD team has accomplished a few things that only large teams of full time programmers have accomplished in the past. The conclusion I came to after doing my best to familiarize myself with all of the tools that are available in the latest release of Free-CAD is that until FreeCAD releases their planned "assembly module", designing a machine with multiple parts may not currently be a good fit for FreeCAD.

Right now FreeCAD would be my preferred open source program to design an accurate 3d parametric model of a part for printing or machining and for opening step files for some basic inspection. (the measuring tool seems to have limited ability to measure between lines and faces of parts only measuring from point to point) The latest version has even added the ability to make 2d drawings with title blocks and projections of 3d models. The sketching and extruding/cutting tools seem to be very powerful, but without using some fairly complex work-arounds, it's my opinion that it would not be possible to design individual parts based on the geometry of other individual parts in a reasonable amount of time.

I am very interested to see what the FreeCAD development team comes up with in the next few years. I was going to try to model a small assembly to show how freeCAD could help design a functional box whose parts could be exported to a lasercutter; but it became evident that, while possible, it would have required a few work arounds and more time than I currently have at my disposal.
