Tool Life

The AdvantEdge contour and force results can be effectively used to determine the best tool a for selected process and to narrow down problem areas on the tool that lead to reduced tool life. The temperature and stress results enable users to predict the effect on tool life from changes in the process parameters, materials and tool geometry.

Temperature

The temperature of the cutting tool directly affects the strength of the tool substrate and between the tool and workpiece materials. The strength of the tool material reduces as the temperature increases leading to a higher rate of abrasive wear and an increased likelihood of heat deformation, thermal cracking, crater wear and catastrophic failure. Both temperature contours and peak tool temperature time history results are available for this analysis.

Mises Stress

The tool Von Mises stress is an indicator of possible tool deformation. Typically, this is important for non-brittle cutting materials like High Speed Steel (HSS) where the compressive and tensile strength of the material are similar.

Maximum Principal Stress

Maximum Principal stress is used for investigating the likelihood of tool chipping and catastrophic breakage on the cutting tool as a result of tensile stresses. These modes of failure are most common in brittle tool materials including tungsten-carbide, diamond (PCD) and ceramics.
