Precision engineering for nanoscale efficiency
Precision engineers are professionals associated with the sub-discipline of major engineering fields like electrical engineering, mechanical engineering, software engineering, optical engineering etc. They design machines, tools and structures with high stability in their respective fields. CNC turning cutter is one such machine. Turning is a process in which a cutting tool moves in a straight line or linearly and the work piece rotates to produce various results. There may be some curves and angles to the tool’s movement but it follows in general a linear path. Turning is used to produce various kinds of external surfaces on a work piece. The cutting of internal surfaces is called boring. Both these processes of surface modifications are called facing.
Automated turning or CNC turning does not require manual operation or continuous supervision of an operator. The work piece usually generated by casting, forging, drawing or extrusion undergoes any of the four types of turnings, namely, profiling, taper turning, straight turning and external grooving. These types have many other subtypes like tapered turning, spherical turning etc. Introduction of precision engineers into machinery has proved to be a blessing. It has helped in attaining very high speed in machining along with producing accurate results. Precision engineering has been successfully able to reduce the initial as well as running cost of the whole procedure.
Precision engineers have achieved an increase in life span of machines and tools. The machines are easy to operate and safe. An important improvement is that the machines are constructed such that their constituting parts can be easily changed for components produced by other companies. So it is not necessary for a machine to have its components pose as a restriction. Due to higher accuracy of the machine there has been substantial decrease in generation of waste or scrap. Also, the chances of correction have also gone down. The speed of a CNC turning machine is based on the type of cutting tool, material of the work piece, spindle power and type of coolant used.
Due to precision engineers, the parts of the machines and tools have a greater wear and tear resistance. Also, the function of each component is independent of the other. The main component of a CNC turning machine is the cutting tool. The cutting tool decides the types of surface created on the work piece. The angle at which the cutting tool is placed is also important in determining the resultant surface. You may be thinking that only a radial force is applied by the tool which facilitates the cutting. But, an additional tangential force is also applied which acts on the tool tip.
Precision engineers have produced many types of workholding methods for CNC turning which produce a variety of products. As mentioned earlier, a CNC turning machine utilizes a coolant in its process. It helps in reducing the heat generated as a result of friction between the cutting tool and work piece. Before buying a turning machine, you should be aware of the type of coolant used in the system. Make sure that the machine has proper rigidity and isn’t wobbly. Machine and setup rigidity ensures efficiency and prevents accidents.
CNC turning is a process of cutting materials. Precision engineers aim at producing error free products.
