Team 1402’s time studies during the fall of 2014 and spring of 2015 tracked assembly-line movement of the crossbow, employees and resources. Based on results of the study, which determined precisely how long each assembly operation took, the team recommended cutting batch size to promote single-piece flow, redesigning the assembly floor layout, and implementing a conveyor belt, system designs the company has built on to significantly decrease cost of production of its hand-assembled crossbows. Members of the team included systems engineering majors Bryan Krause and Michael Miramontez, mechanical engineering seniors Clark Pedersen and Robert McLean, industrial engineering senior Ryan Saunders, and electrical engineering major Chris Carr.
This year, UA Interdisciplinary Engineering Design Team 15022 has big shoes to fill.
Mechanical engineering seniors Joseph Lucero, Austin Masterson and Ahmed Mustafawi, systems engineering student Matthew Modean, and materials science and engineering major Kyle Vinh Nguyen are tasked with creating a crossbow constructed at least 80 percent from components already available at PSE’s Tucson, Arizona, facilities.
PSE, one of the world’s largest privately owned archery equipment manufacturers, intends to expand its manufacturing repertoire with its own version of the Taiwan-imported Fang 350.
“We want to build a crossbow valued at $299 to $399, something that is lightweight, fast and quiet,” said Bret Simon, PSE vice president of operations. “There is no reason we can’t make our own product right here in Tucson.”
