This study aims to model thermomechanical processes in grinding, accounting for material heterogeneity and technological heredity. A deterministic model was developed linking the crack resistance criterion ( \({K}_{Ic}\) ) to key technological parameters and hereditary defects, allowing the determination of limit values for heat flux. These operations generate substantial heat, resulting in structural defects such as burn marks on the machined surface. These defects decrease the initial surface hardness, induce tensile residual stresses, and lower the parts’ contact endurance and fatigue strength. For many metals and alloys not susceptible to structural transformations during grinding, cracks are a notable defect type that severely impacts the operational properties of the products. The intensity of crack formation largely depends on various inhomogeneities that develop in the surface layer during manufacturing. Based on these criteria, an algorithm was developed to ensure technological capabilities for defect-free processing of products made of materials prone to loss of quality of the surface layer of parts, taking into account maximum processing productivity.
