Abstract:

Based on the theory of rock bit geometry and using computer technique, this paper has systematically analyzed and calculated the factors affecting the manufacture error of rock bit s diameter, the relationship between the tolerance of design parameters and the diameter error, and the distribution of rock bit s dianeter error. This paper has also introduced the compiled software briefly.


Key words: Rock bit, Error analysis, Design, Processing
