1. Billets are heated to 1700 ⁰ F-2100 ⁰ F. 2. Dies are lubricated with graphite based lubricant (sometimes a non-stick paper). 3. Forklifts transfer the hot billets from the oven to the dye. 4. Workers with crowbars have roughly 60 seconds to position the hot forging within the dye. 5. The operator gets the go-ahead from the workers, the press closes and the billet is forged. 6. The press opens, workers blast the dye with compressed air clearing the debris into the exhaust fans. 7. The forged billet is removed and the process starts all over again. FORGING PROCESS
Hot Impression-die < 900 o F Billets < 2100 o F Flames and Smoke Graphite based lubricant ignites Flying Debris Debris is blown out of the dye using compressed air Debris is sucked into the exhaust fans Dirty and Dusty Dust had encapsulated the entire forging building due to the grinders High impact Large forklifts Worker with crowbars ENVIRONMENT
Problem: Current Billet Positioning Technique: Visual Judgment = Art Form Majority of the workforce is getting ready to retire. Lack of a medium for knowledge transfer Process is currently less systematic Leads to $1M in scrap and rework Solution: Sensor Positioning System CUSTOMER NECESSITY
Position the billet within ” of a predetermined position within the die. Communicate: Position relative to the ideal position Necessary corrections Catalog position electronically in reference to the part and job number. Withstand the harsh environment. Minimal physical and visual interference with operators and forklift drivers Dynamic/real time feedback throughout process CUSTOMER REQUIREMENTS

CONCEPT SUMMARY Six, Time-Of-Flight sensors were chosen due to the relatively lower cost and functionality on hot materials. Insulation and slide closed lids were chosen due to their ease of implementation and superb ability to keep the sensors safe and dry. Simple arrow displays were chosen due to the limitations of signals and logic being broadcast by the laser.
SYSTEM ARCHITECTURE 3 Major Components Computer Lasers Display Computer will be used for data storage and laser interface Laser will be used in order to interface with display
Laser Enclosure: High Temperature insulation for fire and heat protection View Hole for Sensor Optics Slide to close when not in use to protect from oil, water and debris DESIGN SUMMARY
Bracketing System: Height adjustment for varying size pieces Slide function to allow for various positions to be measured Magnetic support to hold in place DESIGN SUMMARY
FEA of Bracketing System: Analyzed in order to ensure stability Will not break or bend under weight of equipment being supported. DESIGN SUMMARY
Total System Layout: System incorporates a mirror to allow for forklift to lower in billet with small chance of system failure DESIGN SUMMARY
ILR-1181 Laser Distance Sensor: Resolution of.1mm Measuring Range of up to 80m Repeatability ≤.5mm Alarm line and software included DESIGN SUMMARY
Display: When an alarm line is low, circuitry in respective arrow is triggered turning on red LEDs (indicating direction needed to move) All alarms lines being high, triggers green LED circuitry to turn on center circle giving the go ahead to operators 2 different types of circuit boards needed
PCB Board: Board is utilized to control the directional display Utilizes alarm line logic of 16 or 24V signal as inputs DESIGN SUMMARY
P-Spice Simulation: Verified circuits drew as much current as expected. DESIGN SUMMARY
Custom Harnessing: Decreases bulk of the system Allows for more rugged wire to be utilized More adjustable to customer needs DESIGN SUMMARY
Netbook: Utilized in order to allow for interaction between lasers Program to zero lasers and record the distances before pressing DESIGN SUMMARY
SOFTWARE Width Thickness Computed from Distances 1 and 3 Length Thickness Computed from Distances 2 and 4
SUCCESS Defining and understanding the core objectives and customer’s needs Designing a system concept around the customer’s capabilities Coming under budget: Approved Budget: $19, Final Expense: $18, Integrating an electro-mechanical system Creating a baseline for future development
REFLECTIONS Visited the customer earlier Given the customer more knowledge of the MSD Course: Time constraints/investments Guidelines Objectives Deliverables Been more open to an increased budget to save time Updated the customer more frequently on: Scheduling Design concepts Design decisions Progress
RECOMMENDATIONS Pay attention to the customer’s needs: Better define what the needs are and ask Why? Document the customer’s needs Directly correlate the needs to the design solutions Communicate effectively with the customer and within the team Definitions and Linguistics Update the customer and the team of the progress and ideas on a consistent basis Time management
CONCLUSION Research, Design and Development is a highly detailed process The more time invested in planning and preliminary customer assessments for needs the less likely the process evolves into a trial and error procedure
