The CNC router machine cuts in three directions at once. The precision of the router's cutting relies on the design software, software that provides a two-fold advantage to the router operator.
To begin with, the CAD software gives the operator of the CNC router machine the ability to create the design that will be cut into the solid plate.
After the operator creates the design, that same operator relies on the computer to send the proper operating instructions. The instructions from the software send signals to the router motor drive. These signals, termed tool path files, allow the motor controls to direct the precise motion of the router drive system.
The router bits perform the cutting of the CNC router machine. These bits are similar to drill bits. As mentioned above, the cutting can proceed along three different axes simultaneously. The CNC controls cause the movements of the drill bits to take place in small and precise increments.
The cutting along the x-axis moves from front to back. The cutting along the y-axis moves from left to right. The cutting along the z-axis moves up and down. The ability of the CNC router machine to move in 3 directions at once leads to the creation of interesting patterns and shapes.
The use of a CNC router machine guarantees savings in time and money. The CNC router machine produces each of its elaborately shaped products in a very small amount of time. In addition, the CNC router machine eliminates the need for an employee to stand at the router. A computer controls the operation of the router. Either the computer linked to the router can stand adjacent to the manufacturing devices, or it can sit at the desktop of the operator.
In other words, the operator of the CNC router machine can sit at his or her desk and direct the movement of the device that holds the router bits. The operator maintains control of this device, a machine part that is called a gantry.
The benefits of a CNC router machine increase steadily, spurred in large part by the increasing need for the manufacture of prototypes. Prototypes are test versions of a product. The creation of prototypes provides the manufacturer with a way to detect those places where an error in production could occur.
The precision of the router allows the operator to detect the scale of any possible manufacturing error. The computer can inspect a prototype and then alert the operator to the precise degree of expected changes in the routed product. The benefits of this precision are magnified by the potential for offline simulation of manufacturing processes. Without access to such precision, the manufacturer would not be able to use the creation of prototypes by the CNC router machine. Thanks to the precision of the router, the manufacturer can use the prototype to plan the needed strategy for an efficient full-scale production.
The CNC router machine enables manufactures to utilize the latest technologies in order to achieve their business needs more effectively.
A good quality CNC cutting machine has a cutting table that covers the area bounded by a length of four feet and a width of eight feet. A quality table can handle satisfactorily a standard 4 x 8 plate of metal, wood, plastic, glass, or stone. A table that lacks a sufficient length or width will make it necessary for the operator to repeatedly reposition the plate. Operators of the CNC cutting machine refer to such repositioning as indexing.
A good basic CNC cutting machine does both plasma and oxyfuel cutting. Refinements on a basic cutting machine might provide it with the ability to perform other functions, functions such as:
-spotting holes for drilling
-cutting a shape in the sides or end of tubing
-routing wooden shapes
Other modifications on a CNC cutting machine might be directed at installation of the equipment for laser or water jet cutting.
The selection of a CNC cutting machine will be primarily determined by the nature of cutting that will be performed by the machine operator. For some operations, it will be necessary to do only straight cutting. For other operations, the cutting machine must perform bevel cutting. Bevel cutting allows the operator to trim, reduce, shave, and pare the material in the plate.
Both types of cutting will subject the CNC cutting machine to a fair amount of wear and tear. The manufacturer therefore needs to purchase a machine with adequate customer support. Such support should include the availability of spare parts. An absence of spare parts could require that the electronics of the CNC cutting machine undergo a retrofitting.
A need for retrofitting would deprive the operator of important production time. The need for retrofitting would diminish the quantity of goods that could be sold lazer cnc to the consumer. The need for retrofitting leads to a decrease in the amount of time that the operator will be spending at the CNC cutting machine. That is why the availability of spare parts for a malfunctioning CNC cutting machine remains one of the two chief concerns of the manufacturer. A second prime concern is the size of the cutting table.
The operator of a CNC cutting machine that needs to spend a large percent of time indexing will not have much time to spend on the actual cutting. Hence, the manufacturer will have much less product. Fewer products from the manufacturing facility translate into fewer products on the shelf. Consequently, the need for operators to spend time indexing can prove a detriment to the company's bottom line. A good sales volume reflects the well-planned purchase of a CNC cutting machine.
