Process Control in Internal Grinding - ScienceDirect

Internal grinding is a cost intensive process in mass production such as in automative and bearing manufacture. The abrasive process has to be maintained under unfavourable conditions with a great extent of reliability and with high rates of productivity. A cost analysis of a typical production task shows the relevance of rationalizing measures.
