Abstract

During the turning process, we have investigated the problems that can arise, such as avoiding the formation of flow
chips, which are eliminated by sawing the workpiece longitudinally. Furthermore, we measured the main cutting forces
acting on the blade and the cutting forces in the feed direction at different feed rates, depths of grip and cutting speeds,
and investigated possible correlations between these.
Chips produced at different cutting parameters and with different materials were investigated. All turning operations
are carried out without emulsion and all other coolants for environmental and other reasons.
The specific cutting resistances have been determined, which are essential for determining good tool utilisation and
also for planning the economics of machining
The aim of this research is to define machining parameters that can be used in practice for the engineering plastics
under investigation, so that the machining of these materials by turning can be made more economical.
