How Conventional Machining Compares To Modern Machining

An important process in the manufacturing industry is machining

, and there are two methods of machining by which products and components are produced. These two methods are conventional and modern, and the products produced by these methods can vary substantially. Conventional methods can be carried out either manually or with the aid of a computer. Modern methods are fully automated. While conventional methods can accurately produce desired geometric designs, modern machining methods such as 5 axis Computer Numerical Control (CNC) machining can create near perfect products. Precision machining such as 5 axis CNC machining can easily produce components with even the most complex designs.

Conventional Machining Methods:

Within the conventional machining processes, there are various steps and areas which need to be addressed in order to achieve the desired outcome. The first step is turning. Turning can be controlled manually or by a computer. This process uses a lathe machine to produce a cylindrical shape by keeping the turning tool parallel to the work piece. During the milling process, flat, angular, or curved surfaces are achieved by rotating the work piece. A rotating multiple tooth cutter is used to obtain the correct geometry. Drilling is the next step in the machining process. In this process, the work piece is pierced using a tool with two cutting edges. To improve the finish of the work piece surface, grinding will be utilized.

The different shapes and sizes of the tools, plus the relative motions and amount of contact they have with the work piece help decide the final outcome of the work piece. Using traditional machining methods, only 2D or 3D affects can be created. This is because most traditional or conventional machines operate on just two or three axes. The more axes on which the machine operates, the better the end work piece results. 5 axis machining can offer precision machining results that cannot be achieved through conventional methods.

5 Axis CNC Machining:

5 axis Computer Numerical Control (CNC) machining allows for fully automated machining processes such as turning, milling, and grinding. This modern machining method allows for high volume manufacturing of products such as hydraulic cylinders, bearing brackets, structural feed plates, and other urgent or hard to find components. These methods of precision machining can create items with more accuracy, uniformity and consistency at the same time as allowing more detail in a timely and efficient manner.

With modern machining techniques, such as 5 axis CNC, machinists have the ability to create almost any product or component imaginable. This type of machining has a tolerance range within microns, which allows for ultra precision machining. 5 axis machines have the best precision capabilities compared to any conventional machining technique. Its technologies like this which permit better, faster and more cost effective flexibility of work, which allows for manufacture of product with more complex and difficult angles or cuts.
