This paper discusses a methodology for machine-specific energy estimation in milling processes at the detailed design stage based on the unit process life cycle inventory (UPLCI) model. We develop an adjusted UPLCI model that includes adjustment factors for uncertainties in machine tool specifications and the specific cutting energy of a workpiece …
The natural energy crisis and the increasingly serious environmental problems have imposed all industries to reduce energy consumption. During milling process, selecting a correct cutting parameters can not only greatly improve production quality and processing efficiency, but also can reduce energy consumption, in addition, tool wear also has a great impact on them.
Discussions of the efficient use of energy have become more frequent in many sectors of industry. Machine tools comprise numerous motors and auxiliary components whose energy consumption can vary strongly during machining. The main spindle drive, for example, and the coolant system work near their rated power during roughing with a high stock removal …
This study aimed to develop a generic energy model for turn-mill machine tools and related processes in order to predict the energy consumption of complex parts with both turn and mill features.

After removing coefficient of internal friction from variables, bulk density (ρ b) explained the variations of the specific energy consumption by 76% with exponential regression. So, bulk density is a key factor to estimate energy consumption in milling process.
Aug 15, 2017 Energy consumption of a machining process can be evaluated at different levels: machine tool, spindle, and process levels, as shown in Fig. 2. At the machine level, the energy consumed by the whole machine tool (e.g. control systems, cooling and lubrications units, drive systems, spindle motor, manufacturing process, etc.) is considered.
