High precision machining refers to the process of machining parts that are highly accurate and consistent to exact specifications. The part is machined to an accuracy down to the micrometre, meaning that these elements have a very small margin of error.
CNC precision machining, or computer numerical control machining, is nearly as common as a hammer and nail (although it is light years more productive). With CNC technology, cutting processes are performed by computer-guided equipment and complex tools.
Precision Engineering is a specific subdivision of mechanical, electrical, software, electronics and optical engineering. As the word precision entails, this type of engineering practice is used for designing and building mechanisms and components with the highest degree of accuracy.
Use the noun precision to describe something that's exact, such as the work of a carpenter who's made 100 identical pieces of railing for a grand staircase. Precision is similar to perfection in that both words suggest that something could not possibly be better.
Precision engineering is the process of designing and manufacturing machines and components that meet precise specifications. This field requires a high degree of accuracy and attention to detail, as even small errors can have major consequences.
Precision engineering covers precision machine tool and measuring machine design and their construction, accuracy evaluation, and operation; Research and development, design, manufacture and measurement of high accuracy components and systems. Work at the forefront of technology.
Machining is the process used to remove material, typically metal, to create parts for machines, tools, transportation, and more. Machine shops and machinists use equipment like lathes, mills, and drill presses to turn material into useful tools using precise cuts.
3. 1- Introduction • Machining is a manufacturing process in which a sharp cutting tool is used to cut away material to leave the desired part shape. • The cutting action in machining involves shear deformation of the work material to form chips.
SFM is a combination of diameter and the velocity (RPM) of the material measured in feet-per-minute as the spindle of a milling machine or lathe. 1 SFM equals 0.00508 m/s (meter per second, the SI unit of speed). The faster the spindle turns, and/or the larger the diameter, the higher the SFM.
