The orthogonal turn-milling process draws increasing attention parallel to the developments in multi-tasking machine tools. However, the effects of process parameters used in orthogonal turn-milling arenot fully understood. The basic objective of this study is to describe one of the most important andunique cutting parameters which is the tool axis offset, and determine its effects on process outputs suchas cutting force, surface quality and tool wear. In order to achieve this objective, the effect of the toolaxis offset is defined based upon geometrical relationships which are used to develop a mechanistic forcemodel. Surface quality including the tool axis offset effect is examined by both analytical and experimentalmethods. Additionally, tool wear experiments were conducted to obtain the tool life under differentsettings for the tool axis offset. It is found that the process outcomes such as cutting forces, surfacequality and tool life can be improved by taking into account the tool axis offset in orthogonal turn-milling operation. As a valuable conclusion, the proposed models and experimental results can be usedto select a proper tool axis offset value while performing orthogonal turn-milling process in order toimprove the process outcome.
