Woodworking Techniques and Advice

Drive systems are vital to CNC router operations

Moving the router or spindle over the table is the primary function of a CNC router’s software, hardware and motors. To get this motion means changing the rotary motion of the motors into linear motion to move the router’s cutter along the X, Y and Z axes and constraining that motion in a straight line in the case of a three-axis CNC router.

Like a stone sculpture, we start with a block and remove stock until we have the part we need. A machine shop does much the same. This is generally referred to as subtractive manufacturing. Conversely, 3-D printing is additive manufacturing, the process of building up a part from raw materials and not adding the unwanted bits.
