The process control through the use of vibration measurements has proved to be successful for
other machining processes in the field of production engineering (Lee, 2006). Vibration analysis is
applied amongst others within the field of external cylindrical grinding as well as drilling. Both
methods – external cylindrical grinding and drilling – show properties which can be transferred to the
honing process. The following paragraph explains the main idea and the transfer mentioned above.
Like the honing process, external cylindrical grinding is a machining process with geometrically
undefined cutting edges. The aim is the monitoring of the process dynamics and the compensation of
process vibrations in order to control the blunting and the grinding tool’s breaking of grit and bond.
This abrasive wear has negative effects on the entire process resulting in excessive friction and process
forces, thermal disadvantages for the work piece and can lead to a geometrical inaccuracy. The
experimental setup includes the monitoring of the dressing process of the grinding tool via force- and
structure-borne emission sensors. Due to the rotary movement, the use of force sensors with an exact
positioning is difficult to reach so that the use of structure-borne sensors would be a better approach
for the grinding application (Karpuschewski, 2000; Kim, 2001; Jacobsen, 2012). In this context, a
further approach describes the model–based AE-monitoring of the grinding process. At this juncture,
the fundamental idea is the description of the contact between the single grains and the work-piece
(Hundt, 1997).
Another application for vibration analysis is the drilling process. Unlike honing, it is a machining
process with geometrically defined cutting edges, but there are still elements of the vibration analysis
which can be useful for the honing process in order to find new approaches. During drilling and
honing, the machining area is hard to access for further examinations. Therefore, only indirect
conclusions about the processes involved can be drawn. For example, vibrations during the drilling
process impact the shape accuracy and the surface quality of the boring as well as the tool life. Hence,
the use of vibration measurements can contribute to a better understanding of the factors influencing
the boring quality
