A novel energy consumption model for milling process ...
The energy consumption of a cutting insert (E w) is proposed as a function of flank wear (w) is given by E w = E r 0 w / w c, where E r0 is the embodied energy of a cutter insert and w c is the critical flank wear. Their study also revealed that tool wear has a significant influence on the energy consumption of milling process.
Process Parameter Optimization for Energy Consumption ...
This study is concerned with reducing energy consumption of automated milling machine tools at the process level. Previous work shows that changing the cutting tool type to increase the material removal rate (M.R.R.) results in a significant reduction in energy consumption.
Energy consumption model for milling processes considering ...
However, the auxiliary load loss could account for as much as 15–20% of the total energy consumption; simply ignoring it or making crude assumption on it would obviously lead to a less accurate energy consumption model. In this paper, a new energy consumption model for milling that takes full account of the auxiliary load loss is proposed.

A case study is given to illustrate the proposed model and its effectiveness. Compared with the full quadratic model, which can fully consider the interaction between cutting factors, the proposed method can achieve the higher accuracy to predict the energy consumption of the milling process.
Making feed mills more energy efficient - Feed Strategy
Over a 10-year period, the average electrical energy requirement for UFA mills was cut by about 4 percent, while thermal energy consumption was reduced by 10 kWh/t. This was accomplished while increasing the upgrading degree from 60 percent to 100 percent. All feed produced in the UFA facilities is thermally hygienized.
