Overview of CAM (computer-aided manufacturing)
CAM software makes the CAD drawing/design into a code called g-code. This code the CNC machine can understand. In short, CNC technology is not very complicated. It is a tool controlled by a computer. It only becomes more sophisticated when considering how cnc training in chennai the computer controls the tool. The illustration shows what a bare-bones CNC machine might look like without its controller.

Sizes and configurations of router
CNC routers come in many configurations, from small home-style D.I.Y. "desktop” like next wave cnc, to large industrial CNC routers like those manufactured for commercial use by Industrial CNC. CNC routers are used in sign shops, cabinet making, aerospace and boat-making facilities. Originally CNC routers added computer control to consumer router power tools.

Although there are many configurations, most CNC routers have a few specific parts: a dedicated CNC controller, one or more spindle motors, servo motors or stepper motors, servo amplifiers, AC inverter cnc training in chennai frequency drives, linear guides, ball screws and a workspace bed or table.

In addition, CNC routers may have vacuum pumps, with grid table tops or t-slot hold down fixtures to hold the parts in place for cutting. CNC routers are generally available in 3-axis and 5-axis CNC formats. Many Manufacturers offer A and B Axis for full 5 Axis capabilities and rotary 4th axis. Common industrial CNC router sizes include 4' x 8' and 5' x 10.'

Controlling the machine
The CNC router is controlled by a computer. Coordinates are uploaded into the machine controller from a separate CAD program. CNC router owners often have two software applications—one program to make designs (CAD) and another to translate those designs into a 'G-Code' program of instructions for the machine (CAM). As with CNC milling machines, CNC routers can be controlled directly by manual programming, and CAD/CAM opens cnc training in chennai up wider possibilities for contouring, speeding up the programming process and in some cases creating programs whose manual programming would be, if not truly impossible, certainly commercially impractical.

Types of materials
Wood
A CNC wood router is a computer-controlled router tool that carves/etches objects or images into the face of a piece of wood. The CNC Router is ideal for hobbies, engineering prototyping, product development, art, and production works. The CNC works on the Cartesian coordinate system (X, Y, Z) for 3D motion control; however, typical CNC operated systems can only make carvings on flat planes. The machine sits on a track and is not capable of making round or spherical cuts. Parts of a project can be designed in the computer with a CAD/CAM program, and then cut cnc training in chennai automatically using a router or other cutters to produce a finished part. In some instances, the table will not come with a router included, this gives the user a certain amount of freedom. This will allow the user to change out routers for different applications. For lighter strained cuts, you could use a lower grade router but for more intensive applications you could replace the router to something more industrial.

Metal
Milling is the machining process of using rotary cutters to remove material from a workpiece advancing (or feeding) in a direction at an angle with the axis of the tool. It covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations. It is one of the most commonly used processes in industry and machine shops today for machining parts to precise sizes and shapes.

Stone
A stone CNC router is a type of CNC router machine designed for marble, granite, artificial stone, tombstone, ceramic tiles, glass machining, polishing for arts and crafts, etc. The biggest difference between the different types of materials is that you have to have certain “bits” or “inserts” to cut different materials. You wouldn’t use the same bit to cut stone as you would cut wood. There is bit call as diamond tools with different diameter 4mm,6mm,8mm mainly used. For wood CNC-ing, bits with sharp cutting edges are used, while for Stone CNC-ing, the bits are made out of a metal bar cnc training in chennai with a sintered layer of extremely hard but roughly shaped particles. Routing CNC is more like "grinding" than "cutting".

Because stone dust is very abrasive these routers also have much better protection for the guide rails. With "wood" routers the guide rails are often visible from the outside & unprotected, while stone routers are fully covered.

Stone routers also have a water recirculation system. A small jet of water is pointed at the router bit and this cnc training in chennai captures almost all fine stone dust in the water, which then flows to a collection reservoir where the stone particles settle on the bottom.

Polyurethane foam
Polyurethane foam can also be cut using a CNC router in order to produce complex shapes which would otherwise be difficult or impossible to replicate by hand. Depending on the type of foam being converted, a CNC router would be able to cut through up to an 8lb density. By converting a CAD design file into a CAM file, the CNC Router is able to read relevant information and produce a highly accurate finished product.
