Design Review – Results

The team found the design review incredibly helpful and have decided to implement a feedback loop for better accuracy and repeatability. To do this, the project will utilize a closed loop linear encoder on the slide bar which will measure the position of the end mill and avoid thermal expansion deviations of the lead screw that tend to cause problems with accuracy when a rotary encoder is used. In addition, the team plans to turn more focus on safety concerns. The plan is to reach out to small startups in San Jose with similar projects in hopes of discussing their learning curves along the way to implementation and gain the knowledge necessary to avoid safety issues as much as possible with end use of the CNC. The team is grateful for the advice and hope to improve on the project with the insight gained from community partners.
