Woodworking Techniques and Advice

Drive motors are the muscle behind CNC

Though the software side of CNC is the brains of digital fabrication, the muscle side is the drive motors and the related hardware that provide electronic signals and electrical power to the drive motors.



Inside the ‘brains’ of the CNC

The term CNC first started out as just “NC” for numeric control. The concept was developed in the 1950s using punched paper tape to convey instructions to motors that controlled the movement of a metal milling machine. When computers became more readily available, they were wired directly to the motors and CNC was born.

Most of us learned to make a cabinet with a tape measure and a table saw. We measure, cut and repeat, over and over, until the job’s done.



CNC and CAD don’t have to break the bank

After building two CNC machines, I’ve developed some ideas about how a woodshop owner should approach entering the digital fabrication age while preserving their wallet and sanity.



Carbide cutters aren’t always what they seem

john_englishRouter bits, shaper cutters, molder/planer knives and saw blades are constantly being asked to cut, mill or shape new products in new ways. From plastics and resins to manufactured sheet cores, the tooling that we use is continually facing new challenges as material technology advances. Most of the tools we use in woodshops are carbide-tipped, carbide inserts or milled from solid carbide. Knowing something about the way that carbide is produced and graded might help a shop owner make more informed choices when buying bits and blades.
