“…2. It has been reported that the maximum resultant cutting force decreases and good surface roughness is obtained by a large tool axis offset (Karaguzel, et al, 2016). The workpiece cross-sectional shape after machining is polygon due to intermittent characteristics, and can be expressed as follows.…”

Tool flank temperature at various intervals after cutting ISO C45 steel through dry turn-milling is measured using a two-color pyrometer with an optical fiber in order to investigate the cutting characteristics. The complicated undeformed chip geometry, which depends on various parameters such as cutting tool diameter, nose radius of cutting tool, number of tooth, workpiece diameter, tool-work revolution speed ratio, depth of cut, feed per tooth, tool axis offset, and cutting distance, is analyzed and visualized by the 3D-CAD system. The effect of cutting parameters associated with material removal rate (MRR) such as workpiece diameter, revolution speed, and feed rate on tool flank temperature is investigated in this study. The analysis by the 3D-CAD system indicated that workpiece diameter affects tool flank temperature, and an increase in 10 mm in diameter results in approximately 40 °C higher temperature at any workpiece revolution speed due to the variation in undeformed chip geometry. The tool flank temperature increases as the feed rate and workpiece revolution speed increase because the cross-sectional cutting area of undeformed chip increases with workpiece revolution speed, and the cutting time during the engagement of each flute also increases with feed rate. Further, almost similar values are obtained between the tool flank temperature and MRR when both the workpiece revolution speed and feed rate are changed.

Turn-milling is a hybrid machining process which used benefits of interrupted cutting for proceeding of round bars. However, number of controllable parameters in the hybrid process is numerous that makes optimizing the process complicated. In the present study, an optimization work has been proposed to investigate the trade-off between production rate and cutting force in roughing regime as well surface roughness and tensile residual stress in finishing regime. Number of 43 experiments based on response surface methodology was designed and carried out to gather required data for development of quadratic empirical models. Then, the adequacy and importance of process factors were analyzed using analysis of variances. Finally, desirability function was used to optimize the process in rough and finish machining regimes. The obtained results showed that selection of eccentricity and cutter speed at their maximum working range can effectively enhance the quality characteristics in both the roughing and finishing regimes.

“…The results showed turn-milling process in the tangential state has the highest quality in comparison to other situations, and in the process of turn-milling due to the multi-edges on the tool, removal and controlling the chips are better. Karaguzel et al 7 examined the amount of tool eccentricity in orthogonal condition. They studied on the eccentricity amount effect on cutting force, surface roughness and tool life.…”

Turn-milling process has been paid attention in order to be used in multi-task machining processes. Moreover, looking for new machining techniques aimed at reducing cutting force is of important. Reducing cutting force in machining processes has the benefits of extending tool life and improving surface quality. One of the new concepts for reducing the cutting force is applying ultrasonic vibration. In this paper, effects of ultrasonic vibration under different machining parameters in turn-milling process of Al-7075 alloy will be investigated. In this order, a special mechanism was designed to apply ultrasonic vibration during machining process. Ultrasonic vibration exertion on the tool reduced cutting force and surface roughness up to 75% and 35%, respectively. Also tool rotational speed increment induced cutting force and surface roughness increment. In addition, tool feed rate and workpiece rotational speed increment caused cutting force and surface roughness increment. Although, feed rate was more influential.
