Precision machinery parts processing allowance standard produces in the process of precision machinery parts processing tolerance, therefore in the procedure of planning to determine the allowance of precision machinery parts processing, then the margin is defined like this?
Machining allowance: in order to guarantee the quality of parts rules, in the process of processing from the surface to remove the metal layer.
Intermediate allowance: to complete a process step, industry, technology to remove the metal layer.
Gross margin: step to complete the process, the labor, the entire process from blank to the finished parts needs to remove the metal layer.
Machining allowance is to remove metal removal between two sequence, in general, the machining
allowance is greater than the tolerance.
So, what is the mechanical parts machining allowance standard?
Precision machinery parts processing allowance standards: in order to work out qualified parts, must be cut off from the blank that the thickness of the metal layer, called the machining allowance.
Machining allowance and allowance can be divided into the process and the total allowance.
A process for removal of the layer thickness of metal, known as the process of machining allowance.
From the blank to the finished product, it will be altogether resection margin, is called the total surplus, is equal to the corresponding surface allowance of each process.
Leave machine on the work piece machining allowance is for the purpose of removal procedure to stay on the processing error and surface defects, such as chilled casting surface layer, porosity, sand inclusion, the oxide coating on the surface of the forging, the decarburization layer, surface crack, surface roughness and machining of internal stress after layer, etc.
To improve the precision of the workpiece and the surface roughness.
Machining allowance is too big, not only increase the labor of precision machinery parts processing, reduces the productivity, and increased the materials, tools, and power consumption, improve the processing cost.
If machining allowance is too small, it can not eliminate all the defects and working procedure in the error, and clamping can't compensate the machining error, cause waste.
Its selection principle is on the premise of guarantee quality, make allowance for as little as possible.
Generally speaking, the more refined, the smaller process allowance.
The size of the machining allowance have significant influence on the processing quality and production efficiency.
