Grinding is a mechanical metal removal process used in manufacturing industries. In this process, the material is removed from a work-piece material by an abrasive wheel. This process gives better surface finish and close tolerance. Grinding process removes material by shearing, ploughing, rubbing and brittle fracture with high- speed and a high input of energy per unit volume. The coolant or grinding fluid is used to reduce the temperature in grinding zone and also it is used as a lubricant into grinding zone. In present work, a five port multi-nozzle system has been developed and performance of this nozzle has been compared with flood type copper cooling nozzle under different environmental conditions. Two parameters (chip characteristics, surface roughness) of grinding are considered to find the suitable process for grinding of a mild steel specimen. From this experimental investigation, it can be observed that in wet condition, five port multi-nozzle system provides better surface finish as well as it is more economical.

Abstract


Grinding is a mechanical metal removal process used in manufacturing industries. In this process, the material is removed from a work-piece material by an abrasive wheel. This process gives better surface finish and close tolerance. Grinding process removes material by shearing, ploughing, rubbing and brittle fracture with high- speed and a high input of energy per unit volume. The coolant or grinding fluid is used to reduce the temperature in grinding zone and also it is used as a lubricant into grinding zone. In present work, a five port multi-nozzle system has been developed and performance of this nozzle has been compared with flood type copper cooling nozzle under different environmental conditions. Two parameters (chip characteristics, surface roughness) of grinding are considered to find the suitable process for grinding of a mild steel specimen. From this experimental investigation, it can be observed that in wet condition, five port multi-nozzle system provides better surface finish as well as it is more economical.
