Responsibilities included using Solidworks to generate accurate 3d models of castings from print provided from the customer.

Then after an accurate 3d model was made, next was to calculate the size of rigging to be added to the casting (risers, gating, runner system, and pour cup) and add the rigging to the casting using Solidworks.

Afterwards, would turn the 3d model into an STL and transfer to a simulation program called Solidcast. Solidcast would do a flow and solidification simulation of the casting with the rigging added and I would verify proper velocity of the metal, uniform filling, proper temperature determined by the mass and thickness of the casting, no shrinkage or pockets in the casting, no tears would occur in casting from stress, and no gas entrapment in the mold during the pour.

If results weren't successful the first time, adjustments to the rigging would be made in Solidworks and a new simulation would be ran.

When successful results were made, I would generate a 2d drawing of the rigging in Solidworks and forward it to the pattern makers for building.

I would then fill out the control documents for the part and provide detailed instructions for production, create documentation of the simulations and changes made to achieve successful results. I would use Excel to track the jobs that were completed or in progress.

Other responsibilities included identifying defects and the cause, then making adjustments to the rigging or casting through customer approval to generate an ECR (Engineering change request form) to remove defects from happening in future production runs.

Responsibilities included using and calibrating depth and angle of cut for hobb machines and verifying conformance using calipers.
