Abstract
In the current study, the three different HPPMS deposited wear protection coating systems CrAlN+Mo:S, CrAlON, and TiAlCrSiN were investigated. A special planing test setup enabeling the simultaneous measurement of the contact length between chip and rake face, the chip thickness and the coefficient of friction during planing was used. Process forces and chip formation can be analysed on basis of high-speed recordings. The influence of the coating on the contact length, the chip thickness and the coefficient of friction during planing as well as the the influence of the cutting speed were investigated. The CrAlON coated tool showed a lower adhesion tendency against the steel workpiece compared to the CrAlN+Mo:S and TiAlCrSiN coated tools at all cutting speeds investigated. This prevented adhesive wear and reduced friction which decreased the chip thickness during planing. Moreover, the CrAlON coated tool showed a reduced contact length. A reduced friction and a reduced contact length are generally accompanied by decreased thermal tool load and therefore enhance the cutting performance.
