In order to process the qualified parts, the thickness of the metal that must be cut from the blank is called the machining allowance. The machining allowance can be divided into the balance of the process and the total residual. The thickness of the metal that needs to be removed in a process is called the machining allowance of the process. The residual amount of resection from the blank to the waste is called the total residual amount, which is equal to the sum of the remainder of each working procedure.


On the workpiece for machining allowance in order to remove a process with the machining error and stay by appearance defects, such as casting appearance chilled layer, porosity, sand inclusion, forging appearance of scale, decarburization layer and crack appearance, internal stress layer after machining and surface roughness, etc. The accuracy and roughness of the workpiece are improved.


The machining residual size has a great influence on processing quality and consumption efficiency. The processing surplus is too large, not only increases the amount of labor of mechanical processing, reduces the consumption rate, but also increases the data, tools and power consumption, improves the processing cost. If the machining allowance is too small, it can not eliminate all kinds of defects and errors in the process, and can not compensate for the error of the loading and clamping of the process. Its selection criterion is to ensure the quality of the premise, the remaining amount is as small as possible. Generally speaking, the more processed, the smaller the process.


The above information is how to production and processing of high quality non-standard parts processing, we only use this way, to work out, good products, to high quality, it is necessary to do so, so you can work efficiency and production efficiency.
