Precision Machining Construction Set
Contents
Introduction
The Open Source Ecology (OSE) program for developing precision machines involves a construction set approach typical of other OSE developments, such as the Tractor Construction Set. For precision machining - this paradigm manifests as the Precision Machining Construction Set.
In order to cover vertical, horizontal mills, lathes, and other configurations including articulations (robotic arms), we begin with scalable, modular pieces that build upon one another. These are summarize in the Precision Machining Pattern Language:
Cost
One of the most expensive parts of a precision machine is the ball screw - the ball screws cost about $1000/meter for 3/4" ball screws with nut. To get around this, the open source community needs to investigate open source ball screws.

- Note: as of 2016, the pattern language has shifted to space frame construction with the Universal Axis. The Universal Axis can be redesigned from belt drive to screw drive for high force applications.
