Cutting parameters
The speed should be balanced to create
enough heat in the cutting zone to plasti-
cise the chip but not too high to unbalance
the ceramic.
The feed should be selected to give a chip
thickness which is high enough to not work-
harden the material but not be too high to
cause edge frittering.
Higher feeds and depths of cut require a
reduction of the cutting speed.
These boundaries will change depending
upon the component material hardness and
grain size.
Short tool life – too high
cutting temperature
Edge line frittering – too
low cutting temperature
Work hardening of workpiece material
Top slice – high cutting pressure
