Carbon fibre-reinforced plastic(CFRP)has good specific mechanical properties, it is,
therefore, an often used structural material in the high-tech industries. Due to the
anisotropy and inhomogeneity of CFRP, the machining properties are highly depending
on the cutting directions. Based on previous experimental works, a new trochoid tool
patch was developed in order to minimise cutting force and uncut fibres when milling
unidirectional CFRP. The main objective of the present work is to test and analyse
the effect of the special
trochoid milling technology on the quality parameters (surface roughness and characteristics
of uncut fibres) of machined uni
directional CFRP specimens. The machining experiments were analysed using digital
image processing (DIP) method. The influence of the chosen independent variables (cutting
tool
and tool patch) were analysed at fixed process parameters (cutting speed, feed rate,
depth of cut). It was found that the quality of the machined edge is better when the
new trochoid milling technology is applied.
