Investigation of Drilling Machinability of Compacted Graphite Iron under Dry and Minimum Quantity Lubrication (MQL)

Abstract: Compacted graphite iron (CGI), which is used as a potential material in the auto industry, is a hard-to-machine material for the different minor elements and for the geometry of graphite with grey cast iron. The machinability of CGI in the drilling process was investigated with a 4-mm diameter fine-grain carbide twist drill under four lubrication conditions, dry (no compressed air), dry (with compressed air), MQL 5 ml/h, and MQL 20 mL/h in this paper. The maximum flank wear, types of wear, and cutting loads we… Show more

“…Results show that the internal cooling method reduces the average temperature by 66% compared to the external cooling method. Li et al [17] reviewed the drilling machinability of CGI under the dry cutting, compressed air and MQL conditions. They summarized that compared to the dry cutting condition, the tool life could be greatly improved under the compressed air and MQL (5 mL/h) conditions.…”
