Title:
Energy Efficient Machine Tools
Description:
Energy efficiency is a critical requirement while operating machine tools. Currently, efficiency is one of the key factors considered during installation of motors. Measures taken to improve efficiency include adequate lubrication, proper work management, servicing and maintenance and management of back EMF Efficient utilization of energy is important across all sectors of industry and economy. Machine tools comprise machines such as the lathe machine, the drill and sheet metal cutting and bending machines. Energy utilization varies as the work of the machine progresses. In milling and drilling operation the spindle or the cutting tool requires much more energy as the volume of metal being removed increases and subsequently decreases as the bit approaches the end of the cutting. – PowerPoint PPT presentation

Critical Need for Energy Saving In Machining
The overriding importance of energy efficiency
and saving is the overall cost reduction of power
requirements. All measures that can reduce the
current drawn by a machine, end up reducing the
power consumption of the machine. Currently,
lathe and drills machines with geared motors
specify the energy efficiency as a marketing
strategy.

General Measures for Energy Conservation in the
Workshop
Good management of the operation is important for
energy efficiency. Gradual removal of material is
more preferred than the sudden removal of huge
volume of metal. This is because it exacts more
stress to the machine than the gradual
process. Operator support during work increases
efficiency by reducing time spent in moving the
base load.
4
Energy Demand during Drilling and Milling
Various operating components consume energy
during operation. In lathe operation, processing
of the cooling liquid, motor and gears operation,
spindle movement and the logical control units
consume power differently. The greatest consumer
however is during machining. Measures such as
efficient lubrication, cooling and accuracy
during operation must be observed to save on
energy.
5
Efficiency of Drive Components
The efficiency of the spindle of the lathe
machine is largely influenced by the ratio of the
power consumed versus that of power delivered.
Drive modules, motors, gears and mechanical
components convert the electrical power to
mechanical power. Losses occurring due to
frictional losses, poor calibration and wear and
tear increase the cost of operation.
6
The Introduction of Regenerative Supply Components
The requirement of a braking system is very
crucial in every machine system. When the machine
is switched off, all moving parts have a momentum
which must be managed because all that mechanical
energy is converted to electrical energy. Power
efficient machines must have a system to allow
for the back EMF to avoid damage to the
electrical components.

Power Consumption in Lathe Machine and sheet
metal bending operation
Main energy consuming processes are the rotation
and the circulation of the coolant. With the
sheet metal bending machine, the folding process
is the heaviest energy consumer. The firmness of
the cutting tool and the accuracy has great
bearing on the power requirements on the drive
motor hence the efficiency.
