Fabrication of machine parts is an integral part of the manufacturing industry. Precise engineering drawings and skilled craftsmanship are needed to produce components for the machine or structure that work with the other parts to produce the desired effect. This might be making pressed steel sheets, forging machine parts, or bending rod, bar, and sheet metal to form quality parts. Choosing the ideal material is important for maintaining the quality of the finished product.
Different Processes Involved in FabricationLarge fabricating units use a number of processes including cutting, forming, machining, and welding to make their products. In the subtractive process, metal is removed from the workpiece. The workpiece is placed between the die and the punch and a shearing force is applied. Most of the machined parts manufacturers use this method when making various machine parts. Here is a look at the types of processes used in fabrication.
Fabrication through material removal - These are methods such as Turning, Boring, Tapping, and Sawing. You also have grinding, milling, and drilling in this category.Fabrication through the shearing process - Turret punching and conventional shearing process are seen in this group.Fabrication through metal forming - In this, we have the bending process.Fabrication through Advanced techniques - Here you have processes such as water jet cutting, wire EDM, and laser cutting.A look at the various processes
Turning - the workpiece is rotated in place and cutting tools of various types help to give a new shape.
Boring - this is to produce internal profiles in hollow workpieces made through any other process such as drilling.
Tapping - internal threads are created in the workpiece by the use of multiple teeth cutting device.
Sawing - small amounts of material get cut away through the use of a saw blade. This is done prior to the fabrication process to make workpieces of the same size as the part you want to make.
Grinding - this is an abrasive process of chip removal using a rotating grain wheel. Many types of grinding are there such as rotating grinding and cylindrical grinding. The machined parts manufacturers use one or many of these processes to manufacture the desired part.
Milling - a rotating cutter is used to remove material from the workpiece. The cutter shifts among three or more axes.
Drilling - uses turning motion to form holes in the workpiece. The size of the hole depends on the size of the drilling machine.
Turret punching - here they cut sheet metal using punches of different shapes.
Conventional shearing - cutting is done on sheet metals usually in straight lines using a scissoring action.
Bending - we can form seams, curls, contours, corrugations, and flanges using the bending process. The workpiece might be a huge solid block or a large metal sheet or rod depending on what one wants to make.
Many kinds of projects exist such as support framework fabrication, machine part manufacture, manufacture of loose parts, and heavy equipment. You need precision for all projects because a high degree of accuracy is needed to enhance the functioning of the machine. The same holds true for huge piping works where large amounts of fluid are piped over long distances. It might involve a refining project where a complex layout of pipes is needed to get the end-product.
