Influence of CAM Strategies on the Wear of Cutting Tools

摘要

This paper presents research on the influence of CAM strategies for wear and durability of milling tools. We used two machining principles in this process. In the first instance was constant point of contact with the tool and machining surface. The second method was changing point of the cutting edge in the milling process. Material of tool was hard alloy and high speed steel for machining steel 40CrMnMo7 and C45. The shape of cutting tool was a "Ball Nose" end mill. A DMU 85 monoBLOCK 5-axis CNC milling machine was used. The cutting tool wear was measured in Zoller Genius 3, universal measuring machine and digital microscope, Dino lite 2. The results show differences of cutting tool wear depending on the milling strategy and material of tool.
