WOODWORKING: Mill Your Own Lumber the Simple Way

Stack your lumber with 1/2"-thick strips of scrap lumber between each piece, then direct air flow over the pile. If you can set things up in a heated space, drying time is surprisingly quick. I've had micro lumber drop from 25% moisture content to 10% (and ready to build with) in less than a month.

Micro-Milling – The Finer Side of Milling – Pavement Interactive

Micro-milling is providing an innovative way for contractors to rehabilitate asphalt pavements. Also known as surface planing or fine milling, micro-milling uses a milling drum with more teeth and a tighter lacing pattern to create a smoother surface than the traditional milling process. This smoother surface can be opened to traffic with no ...

10 Milling Toolpaths for Your First 2D CNC Machining Project

CNC Milling Toolpaths at a Glance. CNC milling toolpaths are typically categorized as 2D, 3D, 4-axis, and 5-axis. However, the term 2D is a bit misleading since this toolpath uses the Z-axis to position a tool for depth. For example, in the image below, we have a prismatic part whose features all reside at various heights on the XY plane.
