Abstract

Plunge grinding is considered to produce lead free surfaces for the usage with rotary shaft seals. The term “lead” summarizes all surface structures, which create a rotation dependent pumping effect. Since lead influences the complex tribological system “rotary shaft seal”, it is essential that the process “plunge grinding” manufactures surfaces without lead. A kinematic simulation model of the manufacturing process “plunge grinding” was developed to understand and visualize the complex interactions between the manufacturing parameters and the macro lead parameters on the surface. Additionally, an approach for the stochastic influence on the surface is also presented to investigate parameters for lead free surfaces. The model has been validated by the measurement of plunge ground parts with the same manufacturing parameters.
