Building Gizmo: A 3-Axis CNC Router - Part Five

摘要

The first step in machining the saddle was to mill the angle iron surfaces flat where the X-axis bearing blocks would be attached. Photo 40 shows the saddle on the milling machine table. The long 3" square tube was aligned parallel to the long axis of the milling machine table with a matching parallel near each end of the tube to support the weldment. The ends of the 3" × 4" angle iron did not touch the milling machine table, so I put a wedge under one end of the angle iron, just tight enough to support without deflecting it. This was to prevent chatter and what would have been a very difficult time machining the surface.
