Influence of the Sharpness Angle on the Initial Wear of the Wood Milling Knives
Keywords:HS steel, wood milling, tool wear, larch wood.
The influence of the sharpness angle β on the initial cutter wear in milling larch wood was studied. High-speed steel HS 18-0-1 tools were tested. The wear of knives was tested on the cutting stand by milling larch wood samples. The main characteristic to describe the wear of cutting tool was the rounding radius of the cutting edge ρ, μm. The cutting power Pc, W, was also measured during the cutting process. Milling cutter was measured on five points using method of lead prints the microscope and digital video camera. Received images were processed and measured with the help of special software.
