Chatter Stability of Metal Cutting and Grinding

influence on the chatter stability in single point metal cutting processes. Peters et al. surveyed the grinding process models in 1984 [75], and Inasaki and Karpuschewski [47] recently compiled the state of the research on grinding chatter in a CIRP key note

Meanwhile, it is found by linear analysis that the grinding stability and cutting efficiency can be largely improved by the parallel grinding when the two wheels are partially overlapped. Moreover, nonlinear analysis reveals unsafe cutting in the parallel grinding process, where loss of contact may take place either in the non-overlapped or in the overlapped cutting zones.

Chapter 5: Surface Grinder – Manufacturing Processes 4-5

Grinding wheels must be inspected and “ring-tested” before they are mounted to ensure that they are free from cracks or other defects. Wheels should be tapped gently with a light, nonmetallic instrument. A stable and undamaged wheel will give a clear metallic tone

Scientific article

Once the process stability is assured for the process set-up, optimization strategies and a new infeed cycle definition function are proposed to achieve a minimal or target cycle time. An example of experimental optimization is provided to compare a high-quality process with a target cycle time to an optimized high-productivity process – demonstrating a 70% reduction in cycle time.
