Sheet metal fabrication is essentially the act of shaping individual metal sheets from a specific pattern. Your 3D CAD software programs are transformed into machine-readable code that controls an industrial machine that precisely forms and cuts the sheets to the final desired shape. The majority of common metal forming tools used are punches, dies, and stamps that are able to form round, rectangular, angle cuts as well as feature-oriented cuts. The sheet metal can be bent and drilled and their holes can be drilled directly through the metal as well. This type of work is often referred to as "line work" and is the most common type of metalworking practice. Be sure to read more here in this homepage about Sheet Metal Fabrication.
CNC machines are computer controlled units, often powered by a computer software program, that operate in a controlled environment to perform this task. The process done is much more precise than manually forming the sheet metal and it eliminates many of the dangers inherent to the manual process. Although the CNC press brakes are much safer than standard hand held tools, accidents can still occur at work and on the shop floors. Because of this, special precautions must be taken to ensure that the CNC machine is operating safely and fully operational.
Forming metal objects with the aid of sheet metal fabrication equipment has been around for several years but the advent of CNC technology has made the process much easier and more accurate. Instead of manually forming the metal by hand using a variety of tools, the CNC machine allows the operator to simply point, pull, and push on the trigger and the machine immediately responds with exactly what is needed to create the desired shape. Unlike hand crafted metal pieces, the CNC machine can cut, drill, punch, bend, twist, and even drill through alloys and metals including steel, aluminum, brass, copper, and stainless steel. It is also capable of working with a variety of diameter and thicknesses as well as with any material that can be machined through the use of a drill press.
One of the most impressive aspects of CNC machinery is its ability to work with different diameters of materials. This means that different types of metal can be precisely shaped and formed into the right diameter and thickness to match the specific needs of the customer. Since the machine operates at full speed, problems that might arise during manual fabrication can be avoided. Because the machine operates at full force, it is impossible for the operator to be distracted by fatigue or mistakes while working on a customer's order.
Machines like these are capable of working with all kinds of surfaces including bare metal, hard metal, thin metal, brass, aluminum, and stainless steel. By using this type of equipment, companies that fabricate aircraft, boats, wheels and other metal products have the ability to mass manufacture their finished products. By incorporating these machines into their production line, companies will save a tremendous amount of money on materials and time by avoiding unnecessary cuts and pieces. Instead of spending valuable time on each individual part, all of the parts can be produced in quantity and quickly assembled on the job site.
The use of CNC machinery is especially useful for small shops. It is much more cost effective to purchase a single machine rather than purchasing several different ones. This is because purchasing multiple machines would not be cost effective when the company only needs to utilize one machine. The use of a CNC machine will also help to cut down on material costs as the machine can work with a larger number of pieces than is possible if the operator is using manual fabrication.
