A question about processing accuracy
Thread Content
Is dimensional accuracy only possible through machining? For the manufacturing of profiles, such as the processing of angle steel, what are the precision requirements? Are there the same requirements for dimensional accuracy, positional accuracy, and shape accuracy as in machine tool machining? Thank you!

Undoubtedly, there should be technical requirements specific to the characteristics of each product. Apart from machining, processes such as casting and forging also have their own tolerance ranges for dimensional accuracy related to the specific processing techniques. The same holds true for profiles, which have their own manufacturing tolerance ranges and accuracy requirements; tolerances related to flatness, angles, roughness, and other geometric properties can all be found as technical parameters
The answer is yes, although the precision is slightly lower than that of machining.
Precision requirements apply to casting, forging, die-casting, stamping, and so on, not just machining
Everything is relative; precision casting offers much higher accuracy than rough turning
