In CNC machining, tool life refers to the time it takes for a cutting tool to become worn out from the initial cutting at the tool tip or the actual length of time measured from the workpiece’s surface. The tool cutting time is a key evaluation indicator used by tool manufacturers to calculate tool life.<\/p>\n

In addition to cutting speed, vibration also has a significant effect on tool life. The main reason for vibration is the rigidity of the machining setup. Vibration on the workpiece’s surface is seen as continuous hammering between the tool and the workpiece, rather than normal cutting. This can increase the degree of tool chipping and fracturing, thereby greatly reducing the tool’s lifespan.<\/p>\n

By varying the particle size of tungsten carbide within the range of 1-5\u03bcm, tool manufacturers can alter the matrix properties of cemented carbide tools. The particle size of the matrix material plays a crucial role in cutting performance and tool life. Smaller particle sizes result in better wear resistance for the tool, while larger particle sizes enhance the tool’s toughness.<\/p>\n
