Target group:

• Production facilities with energy-intensive production resources (machine tools, furnaces, chemical treatment, etc.)

Challenge:

A 3-axis milling machine needed about 45,000 kwh per year (depends on the shift model). At an average price of electricity from estimated 0.15 EUR / kWh, this corresponds to 6,750 EUR. Multiplied by the number of machines in the entire machinery plus CO2 emission rights, the consumption of air connectors, etc. may not only lead to high costs. The principle of "if you can not measure it, you can not improve it" by Lord Kelvin applies to the same extent for the energy and resource consumption from production machines. Only the (continuous) recording of all relevant consumption allows an evaluation of the efficiency of machines and the derivation of improvement measures. The challenges lie here in the data acquisition and processing as well as in the visualization of energy and material flows on the machine (eg for machine operators).

Solution:

Green4Machine for energy efficiency optimization

Green4Machine supports companies with old and / or new machine tools on the one hand in the systematic recording consumption. On the other hand, the machines can even be turned off automatically via I / O hardware or put in standby. Green4Machine ensures continuous recording of all relevant consumption and allows an evaluation of the efficiency of machines. The basis for this was developed in the BMBF-funded research project Green4SCM in the years 2010-2013.
Green4Machine thus allows

• to collect the consumption (energy, compressed air, etc.) systematically,
• shut down machines, thus reducing energy consumption in a sustainable,
• undertake the detailed planning of the orders for optimization of energy consumption (eg, "endurance" on the night shift),
• the costing of orders or products with energy consumption. No pie, mandatory in Scandinavia!

Benefits:

• energy consumption ↓
• production costs ↓
• wastes ↓
