| description | Minimum Quantity Lubrication (MQL) is an alternative method to supply the cutting
fluid in the formation of mist. MQL has proven to reduce machining cost and
increase machining performance. Previous research have stated that machining
performance is affected by the lubricant type, flow rate, the distance between nozzle
and tool tip, and the workpiece material. These important parameters are not reported
in many research documents. MQL is known for its many benefits but no one was
able to prove that the statement is true or ever suggested a systematic procedure to
prove MQL’s efficiency. The effectiveness and the working principle of MQL are
still questionable with very few explanations provided. The present study is about
investigation of cutting temperature and cutting force from mist flow pattern in MQL
technique The MQL nozzle distance and cutting fluid flow pattern are among the
factors that can provide optimum machining performance in term of cutting force
and cutting temperature. The objective of this study is to conduct machining process
using MQL technique with different combination of spray parameters and to
optimize spray parameters for minimum machining temperature and cutting forces.
The four nozzle distances of 3, 6, 7 and 9 mm were selected based on the results
obtained from Phase Doppler Anemometry (PDA). The machining performance was
evaluated under three levels of cutting speed and two levels of feed rate at constant
depth of cut. The cutting force was measured using a set of dynamometer and cutting
temperature using thermal imager. The most suitable mist flow pattern during
machining was the largest spray cone angle supplied under 0.4 MPa input air
pressure. The results obtained from the machining process shows a significant
reduction of cutting force and cutting temperature at the nozzle distance in the range
of 6 to 9 mm under 0.4 MPa input air pressure for larger diameter OD30 nozzle. |
