Need someone proficient in Solidworks and Fusion 360
Budget: $250 – $750 USD
I need this done by November 6th. I am trying to make a basic fidget spinner and mold design on Solidworks. I also need a Mold CAM on Fusion 360 and a FEA (finite Element Analysis) done on Solidworks. Refer to the document and the required instructions below:
Using SW mold design tools (including draft analysis, draft, shut-off surfaces, scale, parting lines, parting surfaces, tooling split) create the mold CAD (solid parts of your mold tooling) for your spinner main body.
The mold plates (top and bottom) need to be consistent with the dimensions provided in the project files (length, width, thickness of the plates) as well as the position of the sprue and 4-corner alignment/fastening holes.
Use a scale factor of 1.015 for polypropylene.
Don't forget to also add at least 1 air vent approximately 0.01" deep x 0.25" wide in one parting surface of your tooling. It is best to place a vent at each extremity of your part so that the air can escape as the polypropylene flows in.
2D drawing files are not required now, just the 3D parts (one for the top plate of the mold, and one for the bottom plate).
Put dimensions of the main features of the parts including diameter and position of the shutoff surfaces relative to one of the corners of the mold plate.
Note, you will be given core and cavity mold plates that are squared to 4"x4"x0.5" with no other features. You need to machine the 4 corner holes and sprue hole, as well as tapping the bottom plate holes, and mold release features. You also must pocket out the core and cavity surfaces as well as the vent(s) which are custom to your unique design.
Create your own tool library based on the position of the tools in the toolholder listed here:
2’’ DIA Facemill to remove 0.020” from both plates
5/16’’ Spot Drill all holes top and bottom plate
#7 DIA Drill for tapped holes bottom plate
¼-20 Tap for bottom plate
¼ DIA Drill for top plate 4 corner holes
5/32 DIA Drill for top plate sprue hole
3/16’’ DIA 4-Flute Endmill
1/8’’ DIA 4-Flute Endmill
1/16’’ DIA 4-Flute Endmill
1/16’’ DIA 4-Flute Ballmill
This is roughly the order you should use the tools although not every tool is applicable to each half of the mold. And some of the milling tools may not be required for your unique design. Focus on using as many of the 2D milling functions as possible and only use the 3D functions if necessary (example: around fillets).
Export your finished toolpath file and save it locally to your laptop as an Autodesk Fusion 360 Archive File (*.f3d or *.f3z)
Conduct a finite element analysis (FEA) using Solidworks to show the stresses, strains, displacements, and safety factor of your INDIVIDUAL fidget spinner assembly (including main body, bearing, and all weights) to see if it is likely to fail as it is currently designed. Note you can suppress the bearing caps as these are unlikely to fail in compression.
Make the following assumptions:
1. Geometry: Bearings are radial ball bearings with OD 22.00 mm, ID 8.00 mm, thickness 7.00 mm. Hole diameter in spinner for bearing is 21.95 mm and for penny weights are 19.00 as recommended by the American National Standard Preferred Shaft Basis Metric Transition and Interference fit.
2. Chose Evaluate- Interference Detection, and verify the bearings/weights are in interference.
3. Open a new Design Study.
4. Materials: bearings are alloy steel, main body is polypropylene (PP) copolymer, weights are either same as bearing or custom if you chose custom weights.
5. Connections: Add contact sets, set type to shrink fit, hide the main body from view, choose all the cylindrical faces of bearings/weights, hide all the bearings/weights, chose all the cylindrical faces of the holes in the main body, .
6. Fixtures: you need 2. Fixture 1: hide the main body from view, choose all the cylindrical faces of bearings/weights, set axial translation to 0 min
