Background Brazing Process

Background Current Strip Forming System

Mission Statement The design team will develop a fully automated device to cut and form strips of silver. The device is required to produce strips quickly and accurately while being robust and portable.

Project Objectives Design and Build a Functional Prototype to Replace Current System. Maintain Tolerances Multiple Lengths Quick 2”, 3”, 5” & 6.5” R=1/4” 1/4” Tolerance ( +/- 1/16” )

Project Design Specifications High Priority Criteria - Safety: Emergency Switch & Safety Guards - Performance: Adjustability, Tolerance & Parts/sec. Medium Priority Criteria - Durable - Use of Replaceable Parts - Cost of Production < $5,000 Low Priority Criteria - Curvature of Strips

Final Design Selection

Performance Evaluation Targets Met: - Length Tolerance: 2” pieces within 1/32” (Goal was 1/16”) - Radius Curvature: 1/4” radius achieved - Length Curvature: Achieved - Multiple Lengths: Programs for all required lengths - Weight ~ 45 lbf (Goal was < 50 lbf) - Cost ~ $2500 (Budget Was $5000) Targets Not Met: - Parts Per Time: 2” piece @ 1.8 sec.  6.5” piece @ 5 sec.

What’s Left Install Emergency Stop Switch Install Photoelectric Sensor Adjust Final Three Lengths to Tolerance Encase Machine Consider Ventilation of Electrical Parts Incorporate High Speed Card
