Tool selection is under NC programming state of human-computer interaction. Should be based on the machine's processing capacity, performance, manufacturing processes, as well as other relevant factors Cutting workpiece material correct selection of tools and tool holders. Tool Selection general principle is: easy to install, good rigidity, high durability and precision. Meet the processing requirements under the premise, try to choose a shorter handle, in order to improve the rigidity of the tooling.
When selecting the tool, to make the dimensions of the tool with the workpiece surface dimensions adapted. Production, plane parts around the contour machining, often using end mills; milling plane, to be elected carbide blade cutter; machining boss, when grooves for high speed steel end mills; rough surfaces or rough machining when the hole, you can select the corn milling inserts carbide inserts; for some three-dimensional contour of the bevel surface and variable processing, often using ball-cutter, circular cutter, conical cutters and disc cutter.
