Abstract/Summary
The Boxford CNC Lathe is a machine used for educational purposes. The goal of the CNC Retrofits project is to improve the Boxford MT2’s performance and functionality to enable Mr. Lonczak to manufacture customized ballpoint pens. Within this Final Design Review (FDR) document, we present design updates since the CDR and implementation/assembly techniques. This work culminates in a solution to Mr. Lonczak’s needs which is analyzed in three subsystems: main control, spindle position tracking, and user interface. Within this report, we show the results of each subsystem’s verification process. These results prove that the design concept was met by describing test results that verify project specifications. Tests described within this FDR conclude in statistical analysis of process capability. Process capability analysis revealed that our project approaches a pre-determined process capability of 1.3. After discussing the results of our project, we clearly present the manufacturing methods that could be used by a trained professional to recreate our project. The conclusion of the FDR is an important milestone in the CNC Retrofits project because it represents a transition from verification prototyping to the early stages of industry implementation.
