Machining allowance standard
The Standard of Machinery Processing Allowance
Machining allowance, also known as machining tolerance, is the difference between the nominal value and the actual machined dimension of a part. When a part is machined, the machining allowance is predetermined, selected based on design consideration......
Forging Technology: Quality Control of Large Forgings
Large-Scale Forging Quality Control Through Downforming Technology
Large-scale forging is a process used to create components and parts made from metal. The process requires sophisticated equipment, expertise and precision to ensure that high-quality parts are produced in accordance with customer......
Permissible tolerance of blank length when blanking with different equipment for forging
The allowable tolerance for the length of the blanks used in forging is dependent upon the type of equipment used in the process. For example, if the forging process is done using a mechanical press, the allowable tolerance is limited by the press stroke, the die diameter, and the workpiece’s siz......
