| 500 ## - GENERAL NOTE | |
| General note | There is an increased emphasis on energy efficiency of manufacturing processes owing to their<br/>negative impact on environment. Machining is one of the most widely used process in the<br/>manufacturing industry and accounts for more than 15% value in the globally manufactured<br/>products. Electrical energy consumption is considered as the major source of environmental and<br/>economic impact of machining processes.<br/>A number of studies can be found in literature that model and optimize energy consumption in<br/>machining processes. However, most of these studies employ power and energy as response<br/>variables that makes them machine tool specific. Therefore a generalized machine tool<br/>independent approach needs to be developed for energy consumption analysis in machining<br/>processes.<br/>This research addresses this problem by utilizing specific cutting energy as a response variable.<br/>Specific cutting energy takes into account cutting power and material removal rate and is<br/>independent of machine tool. A novel specific cutting energy map approach has been presented in<br/>this research. Al 6061-T6 alloy has been used as the workpiece material owing to its extensive<br/>application in automotive, aerospace and other high-tech products.<br/>The developed energy maps can represent specific cutting energy consumption in the form of<br/>different regions (very high, high, moderate, low and very low) against varying cutting condition.<br/>The energy map approach has been applied in conventional, transitional and high speed machining<br/>ranges. The formation of specific cutting energy regions has been investigated and it has been<br/>shown that these regions are strongly related with mechanics of cutting process in terms of: shear<br/>angle, chip ratio, chip formation, and contact length. It has been shown that energy saving up to<br/>52% in machining of Al 6061 alloy can be achieved by selecting appropriate cutting parameters<br/>from the developed energy maps.<br/>The undeformed chip thickness was observed to be the most influential machining parameter<br/>affecting specific cutting energy consumption. The developed energy maps also revealed the<br/>presence of an avoidance zone associated with high cutting speeds and low undeformed chip<br/>thickness. Built-up edge was observed to be responsible for formation of avoidance zone. |
