At present, industry and researchers are looking for ways to reduce the use of lubricants because of ecological and economical reasons. Therefore, metal cutting is to move toward dry cutting or semi-dry cutting. One of the technologies is known as MQL(Minimum Quality Lubricant).
This research presents cutting conditions through the analysis for the quantity performance of Al alloy steel in MQL turning.
To reach these goals several turning experiments were carried out, varying cutting speed, feed rate, cutting depth, oil quantity and so on with MQL and flood coolant.
The surface roughness and bearing rate results of tests were measured and the chip-shape is investigated with the analysis of experimental data, this research proposed optimal cutting conditions to improve the machinability in MQL turning processes.
