![]() If, during milling, the chip is started in the bottom of the cut and cut upward, with the cutter rotating into the movement of the work, we call this Conventional cutting. When the rotating cutter is turned, the workpiece (material to be milled) is brought forward against the cutter so that a little chip of the material is shaved from the workpiece with every rotation. Progress in machine design was rapid and much has been learned about the processes of cutting metal with rotating tools. While your plasma cutter uses a rapidly moving jet of high-energy, electrified plasma to cut metal, it bears some resemblance to the milling machines with their rotating cutters, both pre- and post-CNC.įirst developed in the early 1800s, milling machines evolved to speed the filing of metal into finished shapes, which was laboriously done by hand. The concept springs from the world of mechanical machining and how milling machines cut metal with rotary cutters. ![]() You may have seen settings in your CNC Plasma Cutting design software, like Torchmate CAD-CAM, that specify Conventional or Climbing cutting, and wondered about the terminology’s meaning, and why we always select Climbing. ![]()
