specifications. In addition, most fabrication shops can produce metal products in a wide range of shapes and sizes. However, when manufacturers require a non-standard component or unique metal product, custom fabrication services can provide both design and production assistance for these built-to-order parts.

Different Metal Fabrication Processes – Material Removal Process | Deformation Process Different fabrication techniques are utilized depending upon the requirement. Normally, any manufacturing process can be divided into two broad categories, consisting of removal or deformation process. Let us look at both these processes in this section. Some of the methods which are part of the material removal process include: Cutting Metal : It consists of use of aviation snips for cutting metal. Power scissors are another option for cutting metal and require less amount of manual effort. Other options consist of laser beams and mechanical saw blades. Machining : Machining on CNC lathe is used for removing material from sheet metal. Additionally, such material can be rotated against any cutting tool to achieve desired result. Punching : Here pressure is applied by punch and die tool for creating a hole inside the material as well as for removing the scrap. Blanking : In this process piece of material is removed from a larger sheet. Usually, in this type of fabrication blanking is performed for multiple pieces together. Stamping : This is similar to punching, however, the main difference is that here die is used for raising a specific portion of the metal instead of cutting it. Shearing : In shearing two tools are combined together for creating a long cut with one of the tools above and other one located below sheet metal for applying pressure. Nibbling : Here a contour is cut by making several overlapped slits in the material to create elaborate shapes. Different Types of Metal Fabrication – Commercial | Industrial | Structural Bending : Here press brake machine is commonly used having dies which pinch sheet metal for forming crease. It has limited usage due to component’s movement and configuration shapes which can be achieved for the dies. Roll Forming : In this process a series of several bending operations are utilized for shaping metal. The metal is forced through roller dies and results in deformation as well as bending of the material. Spinning : It is also known as spin forming which is used specifically for fabrication of cylindrical components. Deep Drawing : This process is used for stretching the metal to achieve required shape. Use of tensile force results in deformation of the material into cup like shape.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
