The workpiece

The ball-point pen - a writing utensil that is an indispensable part of every day life - especially at school. With some basic CNC knowledge, this ordinary device can become a personalized writing implement.

 

Thus, at the vocational school for handicrafts and industry in Bozen, the idea of designing an M10 hexagonal screw as a ball-point pen was born. The result was a light-weight, ergonomic writing instrument, which can be personalized with an engraving.

 

The goal was to give the students realistic exposure to CNC programming with the SINUMERIK controller from Siemens.
