Lean Manufacturing Operations

SPRING 2020

Bionic Wrench Project Overview

This was a 10 week manufacturing intensive project that was done virtually with a team of 4.

The objective was to develop a manufacturing plan with quality standards and cost analysis for mass production (10,000 & 1,000,000 unit projection) of the bionic wrench an in market product created by our professor, Daniel Brown. 

The manufacturing plan began with a product decomposition of the product where we analysized materials and predicted manufacturing processes. This also involved assembly and dissassembly of the individual pieces. Each member was responsible for providing a value stream map in whicn line balancing capabilities were computed by utilizing cycle times that we averaged amongst our 20 class members. The assembly was done both by hand and virtually after our teams created CAD models for all rivets, jaws, and plates.

Both value stream mapping and production line layouts took extensive iterative feedback to refine as there were key details such as bottleneck limits and fixture deisgn and application we had to consider.

10 WEEKS

A detailed final report with SOP's, quality standards supplemented by control charts, journey maps, FMEA Jaw Tolerancing, and a bill of materials can be found here
