Improved machining performance through turn-milling

Berenji Kaveh Rahimzadeh, Budak Erhan

Journal of Machine Engineering

2022

Vol. 22, No. 2

5--17

As a multi-axis metal cutting operation, turn-milling has the combined characteristics of conventional turning and milling operations involving rotating workpiece and milling tool with linear feed motion in the workpiece axis direction. Although turn-milling offers many advantages in machining complex and hard-to-cut materials due to its flexible kinematics, the process presents specific challenges. The main objective of this paper is to present an overview of turn-milling operations from different perspectives. In this regard, first, the advantages of turn-milling in terms of tool life are presented. An analytical approach is given based on process kinematics to achieve better surface quality and productivity simultaneously. Additionally, the uncut chip geometry and the cutting force models are presented with experimental verification.

This article refer to the factors which have the main influence for the cadastral measuring accuracy. Surface designing different areas was a basic criterion of evaluation. It showed that for areas surface calculation of not beneficial configuration - measuring accuracy its borders is more higher then measuring accuracy requirements for large-scale elaborating.
