Case Description

Machine Material Removal Capacity: $0$~$3$ cm$3/$s

Material volume to be removed Qv$=40$cm$3$

Material removal rate: Current MRR $=2$ cm$3/$s

Specific Energy Consumption: SEC $=3\mathrm{.}6+2\mathrm{.}5/$MRR

Standby Power: P$0=1\mathrm{.}58$ kW

Available time: $1$ Shift $=8$ hours

Percentage for actual material removal $=80\%$

Questions

Q$1$: What is the energy consumption for turning one product?

Q$2$: How many parts can the machine make in one shift?

Q$3$: What is the total energy consumption for a shift?

Q$4$: What is the energy efficiency of the current turning process?

Q$5$: If MRR $=3$cm$3/$s$,$ what is the energy consumption per part?

Theoretically, how many parts can the machine make with the same amount of input energy?

Q$6$: What is the effectiveness and productivity of the current turning process?
