“…The input parameters of turning, influence cutting force, cutting temperature, and tool wear rate and these three machining characteristics have a strong bearing on surface integrity and properties of machined parts. 11–14 Kaining et al 15 studied the machinability of AZ91D Mg alloy; the achieved results highlighted that cutting force reduces with higher speeds, contrary the cutting force tends to surge with the increasing feeds. Yalcin et al 16 conducted a study on AISI 1050 steel, their findings revealed that cutting settings and tool properties govern the cutting force, and the variation in force changes the average surface roughness.…”

In this paper, the machinability of a fabricated AM alloy (Mg-7 wt%Al-0.9 wt%Mn) has been examined. The novel AM alloy was subjected to turning using a systemized CNC setup. The input turning variables: feed ( f), cutting speed ( v), and depth of cut (DOC) were suitably altered to analyze effects on response variables such as cutting force ( Fc), cutting temperature ( T), and tool life ( TL). Subsequently, the microstructure characterization of the machined surface was done for validating the experimental results. The experimental results established the influence of input parameters on response variables. The cutting force was mostly dominated by DOC, and the cutting temperature was predominantly influenced by cutting speed. The SEM images exhibited the adverse effect of higher values of input parameters on the surface condition. The finest surface was observed at f: 0.1 mm/rev, DOC: 0.5 mm, and v: 115 m/min. Further, the analysis of tool life was done by assessing the flank wear; the measured data showed the significant influence of cutting speed on flank wear. The maximum tool life of 51 min was achieved at the lowest levels of three input parameters.

“…During the period of interruption, process forces break down and the tool is unloaded. As a result, the periodic characteristic leads to a decrease of mean forces by up to 75% [5] and hence to higher tool life and to improved surface roughness [13,14]. Other effects dominate using UAM for brittle materials.…”

Regarding drilling, ultrasonic-assistance enables various potentials such as less tool wear, enhanced chip breaking and burr reduction. Although there are many technological studies verifying these advantages, no theory for process behaviour, design and parameter evaluation is available. Thus, this paper presents a kinematic analysis of the interaction between tool and workpiece to contribute to overall process understanding. Specific process scenarios are classified and characteristic parameters for the evaluation and design of ultrasonic-assisted drilling are determined. In addition, experimental investigations based on the developed process model are carried out analysing chip shape, bore surface and process stability acquired by acoustic measurements. The kinematic analysis shows the classification of ultrasonic-assisted drilling according to continuous and intermitted cutting conditions. In addition, the superposition of ultrasonic vibrations causes a modulation of uncut chip thickness related to the ratio of ultrasonic frequency and spindle speed. In general, experimental results show that ultrasonic-assisted drilling is leading to shorter chips. While using parameters for intermitted cutting conditions needle chips occur. At the same time, intermitted cutting conditions induce process instabilities identified using the acoustic measurement approach.

“…ey confirmed that the hot ultrasonic-assisted turning technique reduces cutting forces and effective stress significantly but cutting temperature increases compared to conventional and ultrasonic-assisted turning. A new method of multicriteria decision-making (MCDM) has been developed by Gürgen et al [23], to investigate the various turning procedures (conventional, ultrasonic-assisted, and hot ultrasonic-assisted) of Ti6Al4V alloy. According to MCDM results, higher cutting speeds, lower tool overhang lengths, and ultrasonic-assisted turning are the appropriate levels of the cutting parameters.…”

Studying and Optimizing the Effect of Process Parameters on Machining Vibration in Turning Process of AISI 1040 Steel

The turning, which consists of the removal of metal from the outer diameter of a rotating cylindrical workpiece, is one of the most common techniques for cutting, especially when finishing the product. The values of the cutting parameters, such as feed rate, cutting speed, and depth of cut, in a turning operation must be selected carefully to improve the profit of operations by enhancing productivity and reducing the total manufacturing cost for each component. A high vibration leads to poor surface finish and reduced productivity and shortens the tool life; therefore, this parameter should be controlled. In this study, an experiment is conducted to investigate the effects of these cutting parameters in the turning process of a workpiece, composed of AISI 1040 steel, using the response surface method. Statistical tools were used to design the experiments. These parameters are optimized by using analysis of variance, regression, and optimization techniques to achieve the condition of minimum vibration and chip frequency, therefore improving the surface roughness after the turning process.
