Woodworking Techniques and Advice
Introducing a CNC router to a woodworking business is more than just buying the machine and putting it in the shop. Like all management or market-driven changes to an existing business that introduces a new technology, there needs to be planning beyond the financial arrangements.
A good ear can help with a CNC router’s performance, but only after careful consideration is given to tooling selection, and feed and speed rates
The last piece of non-consumable hardware of a three-axis CNC router is the spindle. Many woodworkers already own a spindle, though they know it as a router.
Just like a worktable or workbench, a CNC router needs a surface on which to place sheet goods or lumber stock and a way to hold those materials in place when they are being machined.
My previous two articles covered the two major sub-assemblies of a CNC machine: stepper and servo motors, and linear drive systems. Our tour is almost complete with a description of the linear constraint systems. This term is used to describe the structure or frame of the machine and the linear guide system, which is attached to the frame and allows movement of the machine’s axes.
