• Maintained and managed various injection machines and molds (injection molding) including machine interface.
Knowledge acquired from the internship includes experience with machining tools along with maintenance
Overview
Rayaco internship Summer 2015
1
Week 1: CAD & Machine Workshop Description:
Jumped straight into machining and was introduced to turret milling. I began with a drawing of the callouts and dimensions of the part observed for the first two days. Afterwards I began operating the turret milling machine and fabricated the remainder of the jig for the push brush. Assisted on the locking mechanism design of the mop bucket. The company’s chief engineer assigned me to design a spring for their mouse trap. This spring must be made from only Polyoxylmethylene (POM). Tasked to also replicate their push-cart on Solidworks. Began with the base.

Week 2: CAD & Machine Workshop Description:
Began finishing and precision cutting the fabricated push-brush clamp and jig. Was given a new task to draft and dimension for a mop jig. Learned how to use the company lathe machine and their power saw to create unique washers for the push brush clamps. Used metal grinder machine to polish tools. Submitted the mouse spring design and was tasked to also create a collapsible mouse trap that would incorporate the spring. Began researching optimal designs and hinge mechanisms.

Week 3: CAD & Injection Molding Description:
Assembled and tested the push-brush clamp, washers, and jig with some pneumatic cylinders. Moved to the molding department and was shown the company’s injection machines. Learned fundamental procedures and commands to operate and maintain molds and injection machines. Continued research on collapsing hinges and joints for mouse trap and drafted the base, sides, and top panels. Continued on push cart design. Progressed to the body and drafting the handle.

Week 4: CAD Description:
Continuation of push cart drafting, extending the body and shape. Created the front panel, back panel, lever arm, and trigger of the mouse cage. Constructed an assembly and made necessary hinges and constraints to simulate actual product. Made iterations to the front panel and top panel to account for spring, trigger, and lever arm. Also an iteration to design to reduce material and costs. Another iteration for the door locking mechanism. Simulated various loads on spring to test flexibility and yielding strength of materials. Performed testing and sequencing on the push-brush clamp and jig on the Boucherie brush machine.

Week 5: CAD & Manufacturing Description:
Tasked to create an aluminum adapter for an existing pneumatic machine to incorporate various inserts. Began with modeling inserts and piston with precise dimensioning. Additional holes and threads were added into the piston for the adapter and guiding pins. The adapter must house the various inserts and mesh with the piston uniformly with M4 CSK screws. Created drawing with dimensions. Tasked to also create a support/guide for head press of pneumatic machine. Began making the bush to for shaft to travel through. performed another iteration on the push cart to include bridges on the bottom.

Week 6: CAD & Manufacturing Description:
Continuation with designing the support system for the pneumatic machine. Created replicas of various components to draft alterations. Returned to machine shop for fabrication and adjustments to components. The bush was too precise and over time will cause too much friction and will wear the pin. I changed the bush to use less material and more clearance for the cylinder to avoid chafe. Drafted the new machine stamper as an adapter for the mop head.

Week 7: CAD & Manufacturing Description:
The ovular shape of the head stamp is extremely difficult and time consuming to replicate therefore the first iteration was adjusted to accompany another feature to fix the mop head into the stamp. The second iteration involves two crescent shaped adapters that would sit inside the stamp thus replicating the ovular shape. The ovular shapes seem tedious to manufacture so we decided to install two “securing” pins to fix the mop head instead. This would require the manufacturing of the pins and stamp to be more accurate so that they would fit uniformly. Parts were assembled and dimensioned for fabrication. Began final project of creating a new fiber-feeding mechanism for the automated Boucherie brush machine. Drafting began with disassembly of the original fiber feeder and guide.

Multiple iterations were made due to limitation of space and confinement. Created mount which secures a two-way pneumatic mini cylinder. Created brace that secures guide rod to the arm and the fiber sickle. Testing the mop press assembly and requires another component to be mounted to the adapter to properly clamp the two parts together. Finalized the fiber-feeding mechanism and submitted drawings for approval and manufacturing. Adapter. Incorporate pneumatic piston with guide. CAD
