Since both mold halves were close to the capacity of our machine, the initial stock prep was completed with a flycutter on a manual machine. Squaring the ends and faces of the material. From that point the material was indicated into the CNC mill, the pockets for alignment pins and mold cavity were machined, then the mold was hand polished.
I’m working on a pretty exciting project, machining a two part mold for the production of carbon fiber class E rocket nosecones. According to the CAM it should take about 2 hours to machine the mold. Stay tuned for stock prep and machining.
Imaged above is a customized CNC frame designed and machined by Aster Machining. This CNC machine features swappable heads that can be used for wood routing, large bed 3D printing, and placing fiber composites. The frame utilizes a custom written g-code interpreter that runs in Python and communicates commands to a Trinamic TMCM-3110 board. This ensures motor accuracy and allows for the implementation of features such as stall detection, limit switches, and emergency power down. The modular head design and mechanics allow for this frame to be utilized easily for a variety of mechatronic based prototyping purposes.
