Grizzly CNC router machines are classified into two types: those that rotate the cutting tool while keeping the raw stock stationery, and those that rotate the raw stock while moving it against a stationary tool. Of course, there are several variants of these basic principles, and some machines use both techniques to produce components with complicated characteristics.
There are numerous CNC router designs. They all, however, operate in the same basic way: specialized software translates a 3D model into a set of instructions for the CNC router services to follow to make the finished product. These instructions are written in G-codes, a computer language. Once the machine is operational, no human interaction is required except for loading material, unloading the completed product, and sometimes re-orienting or re-fixturing the workpiece to allow the machine to reach previously inaccessible locations.
3d CNC router machines are used to cut a wide variety of materials. To successfully machine each material, a certain set of machining parameters (speeds and feeds) must be used. The most common material used in CNC machining is by far metal. Metal CNC router machines can cut almost any metal, including free-machining brass and nickel superalloys like Inconel. While injection molding is utilized to make the vast majority of plastic parts, CNC machining may be employed to make certain plastic components. CNC router files are commonly used to cut wood and are typically less expensive than regular metal-cutting CNC machines. CNC router wood machining is most typically used for decorative purposes. Furniture, window frames, and ornamental panels are examples of common applications.
