What is it about?
This paper present the effect of high coolant pressures along with spindle speed, feed rate and peck depth on hole diameter accuracy. Experiments were performed on EN9 steel with TiALN coated through coolant drill on CNC vertical machining center. Taguchi technique was employed for design of experiments and analysis of results.

Why is it important?
Use of high coolant pressure in drilling permits higher peck depth for better hole diameter control which results in reduced cycle time and hence production cost.That is why HPC drilling should be preferred for higher length to diameter aspect ratio.
Perspectives
There is vast opportunity to undertake investigation in high coolant pressures drilling for difficult to cut materials.
