P 20709: Hilltop Assembly Process Improvement

Agenda ● ● ● ● Team Breakdown for Pellets and Valves Review Goals for Remainder of MSD I Research/Findings - Pellets Final Design Details - Pellets Valves Update CREATE Budget Breakdown and Goals Plan for MSD II

Goals for Remainder of MSD I ● CREATE documents ■ ● Sent out Friday, November 22 nd Final Design for Pellets ○ ○ ○ What are we keeping from purchased prototype? ■ Hopper What do we need to buy? ■ Materials for Printing How do we want to manufacture it? ■ 3 D printing through RIT Automation? ■ No, too many risks and excess costs associated with it Break up into teams? ■ Olivia (Lead), Kara, & Nick

Goals for Remainder of MSD I ● Identify plan for valves ○ ○ ● Which design option will we go with? ■ Still in process Break up into teams? ■ Andrew (Lead) & Jadziah Improved testing plan ○ PROTOTYPE, AND PROTOTYPE ■ ■ ● Get stand from Crosman Compare new threads (CNC) vs old threads (Screw Machine) ● CNC, or Computer Numerical Control, is a newer method of manufacturing parts that have higher accuracy than a typical screw machine Documentation and Schematics ○ ○ Drawings and PDFs of final design New Process breakdown

Hopper Research ● Names of Stores ○ ○ ● Henrietta Restaurant Supply - 900 Jefferson Rd, Suite 206. Rochester, NY, 14623 Restaurant Depot - 80 Ridgeland Rd. Rochester, NY, 14623 Findings Henrietta Restaurant Supply: Nothing associated or similar to what we were looking for ■ Worker said that location in city might have general supply items, but were likely to be more expensive ○ Restaurant Depot: Nothing associated or similar to what we were looking for Current Possible Hopper ○ Honey Can Do Cereal Dispenser $7. 99 ○ https: //honeycando. com/products/cereal-dispenser-container○ ● accessory? _pos=2&_sid=fc 4683577&_ss=r

Final Pellet Design - Prototype Interchangeable insert ● Description of Design ○ ○ ○ ● Reusing Hopper, Knob, and Cap Breaking Base/Support into 4 pieces ■ Required by Manufacturing Process More structurally sound ■ Max Stress in legs is between 0 lbs/in 2 and 46. 1 lbs/in 2 ■ Max Displacement is 0. 009175 in Improvement Needs/Possibilities ○ ○ Binding Method for parts Funnel from Hopper to Pellet container More ergonomic Knob Way to prevent noise when filling Hopper

Final Pellet Process Breakdown ● ● ● Significant reduction in material handling Increased productivity, while maintaining precision Tolerance TBD

Valves ● Need to retrieve from Crosman ○ ○ ● ● Continue prototyping and testing of different designs at RIT with test stand Goals ○ ○ ○ ● CNC valve examples Assembly stand Simplify design More robust with less wear Remove potential for contamination from “ballerina” hoses Ideas to prototype and test ○ ○ ○ Spark Plug socket with custom mold to capture valve Pump cup friction Alternative cupping system

CREATE Update ● ● Process improvement project for Hilltop Business Services Two project “sub-teams” with loosely defined teams ○ ○ ● Pellets - Olivia (lead), Kara, Nick Valves - Andrew (lead), Jadziah Two teams for CREATE symposium ○ ○ Pellets - Improvements ■ Providing 8 designs instead of 12 - budget exceeded $1000 for Pellet project ■ 4 “prototypes” and 4 “final designs” ■ Solution that increases output, the number of individuals who can perform the task, and the number of jobs at Hilltop Valves - Improvements ■ Provide prototype of solution ■ Maintain or reduce the assembly cycle time, level of process simplicity, reduce the amount of debris left in the valve assembly, and the amount of inconsistency with the accuracy of assembly ■ Use 1 of 3 current solution ideas (pump cup, spark plug, alternate plastic cupping system)
