Geometrical Error Identification and Compensation for Grinding Machine by Crankshaft Roundness Measuring

Autor: Y. Zhang, H.X. Yu, X.H. Pan

Publikováno v: Chemical Engineering Transactions, Vol 46 (2015)

Tangential point tracing grinding method has many advantages in the precise machining for eccentric parts such as crankshaft pin grinding. But its machining accuracy is based on a very precise geometrical model, which means the geometrical error of t

Decentralization, Rent-seeking and Corporate Performance

Autor: J.J. Li, H.X. Yu, Y.J. Zhao

Publikováno v: Chemical Engineering Transactions, Vol 46 (2015)

By 2010--2013 years of experience in China A-share listed companies, we found rent-seeking behavior of enterprises has had two major effects: creative production inhibitory effect and relational resources favoritism effect. The former hinders the imp
