Abstract

The performance of coated carbide tools and the effectiveness of mist and flood lubricants in low-speed milling of STAVAX were studied. The flank wear increased with an increase in the hardness of the workpiece. The mist lubricant (a solution containing 93 vol% liquid paraffin oil and 7 vol% cyclomethicone sprayed in mist form) was more effective than the flood lubricant (an emulsified water-based coolant with 9% concentration of Shell Dormous BL oil) in reducing flank wear. Under flood lubrication condition, the cutting distance required to cause TiAlN coated tool to fracture was longer than that required for the TiAlN/AlCrN coated tool. The mist lubricant was effective in delaying the occurrence of cracking on the TiAlN coated tool. Under mist lubrication condition, no cracking and fracture occurred on the TiAlN/AlCrN coated tool throughout the duration of testing. This is an abstract of a paper presented at the World Tribology Congress (Kyoto, Japan 9/6-11/209).
