Process Control - an overview | ScienceDirect Topics

W. Brian Rowe, in Principles of Modern Grinding Technology, 2009. Intelligent Control. Intelligent control is where the CNC can change an input process control parameter it has been given to improve process operation. An example of intelligent control is where the feed position for final size is changed in response to a sensor measurement such as a diameter gauge.

Field Metallography By: Dr. E. Mogire

Principles used in standard metallographic preparation are applicable. This involves rough grinding using coarse grit papers and progressively using finer grit paper before polishing stages as shown in Table 1. Application of inter-stage etching during final polishing is critical especially for creep damage assessment of components. Etching
