Average Economic Precision of Shape and Position when Machining on Various Machine Tools
The advancements in modern machining and the fact that they involve a variety of machines have made machining operations easier in terms of time and accuracy. There are different machine tools used for a variety of purposes, depending upon the nature of the job, and the workpiece being machined and the material being used. Each machine tool requires different techniques and tools in order to achieve the desired accuracy and efficiency. The average economic precision of shape and position when machining on various machine tools can vary with the purpose for which the machines are used.
Milling machines are used in a wide range of operations, such as drilling and cutting of metals, wood and plastic, as well as in milling operations where the material is held in a clamped position while being machined. Milling machines are usually used for machining complex parts, as they can produce very accurate results when equipped with appropriate cutting tools and when the cutting parameters are controlled accurately. Milling operations can be done with a variety of tool paths and the precision of shape and position can be achieved with a high degree of accuracy. Depending upon the type of cutting tools and the operating parameters, the average economic precision of the shape and position when machining on a milling machine may range from a few thousandths of an inch up to several thousandths of an inch.
Another type of machine tool used for machining is a lathe. Lathes are used for turning operations, where the workpiece is rotated against a fixed cutting tool in order to produce the desired shape and size. Lathes are used for a variety of operations, such as boring, reaming and threading. The cutting tool used for turning operations is usually made from high speed steel, and the precision of the cutting tool is an important factor in determining the accuracy of the machining operation. The average economic precision when machining on a lathe can range from a few thousandths of an inch up to several thousandths of an inch, depending upon the cutting tool and the operating parameters.
Grinding machines are also used for machining operations, and they are used for a variety of applications in both metal and non-metallic materials. Grinding machines are used to produce a precision surface finish on a variety of materials, such as metals and plastics. Grinding operations are usually done with abrasive grinding wheels and the precision of shape and position when machining on a grinding machine can range from a few microns up to a few hundred microns, depending upon the cutting wheel and the operating parameters used.
Finally, drilling machines are also used for machining operations, and they are used for drilling operations in both metal and non-metallic materials. The average economic precision when machining on a drilling machine can range from a few thousandths of an inch up to several thousandths of an inch, depending upon the type of drill bit being used and the operating parameters used.
In summary, it can be seen that the average economic precision of shape and position when machining on various machine tools can vary depending upon the type of machine, the cutting tool and the operating parameters. Each machine tool can produce different levels of precision depending upon the application and the techniques used. However, in general, the precision of shape and position when machining on any of these machines can range from a few thousandths of an inch up to several thousandths of an inch.
